Background and Purpose: Sodium glucose cotransporter 2 inhibitors (SGLT2i) have emerged as a potent therapy for heart failure with preserved ejection fraction (HFpEF). Hydrogen sulphide (H 2 S), a well-studied cardioprotective agent, could be beneficial in HFpEF. SGLT2i monotherapy and combination therapy involving an SGLT2i and H 2 S donor in two preclinical models of cardiometabolic HFpEF was investigated., Experimental Approach: Nine-week-old C57BL/6N mice received L-NAME and a 60% high fat diet for five weeks. Mice were then randomized to either control, SGLT2i monotherapy or SGLT2i and H 2 S donor, SG1002, for five additional weeks. Ten-week-old ZSF1 obese rats were randomized to control, SGLT2i or SGLT2i and SG1002 for 8 weeks. SG1002 monotherapy was investigated in additional animals. Cardiac function (echocardiography and haemodynamics), exercise capacity, glucose handling and multiorgan pathology were monitored during experimental protocols., Key Results: SGLT2i treatment improved E/e' ratio and treadmill exercise in both models. Combination therapy afforded increases in cardiovascular sulphur bioavailability that coincided with improved left end-diastolic function (E/e' ratio), exercise capacity, metabolic state, cardiorenal fibrosis, and hepatic steatosis. Follow-up studies with SG1002 monotherapy revealed improvements in diastolic function, exercise capacity and multiorgan histopathology., Conclusions and Implications: SGLT2i monotherapy remediated pathological complications exhibited by two well-established HFpEF models. Adjunctive H 2 S therapy resulted in further improvements of cardiometabolic perturbations beyond SGLT2i monotherapy. Follow-up SG1002 monotherapy studies inferred an improved phenotype with combination therapy beyond either monotherapy. These data demonstrate the differing effects of SGLT2i and H 2 S therapy while also revealing the superior efficacy of the combination therapy in cardiometabolic HFpEF., (© 2024 The Author(s).

Background: Steroidal mineralocorticoid receptor antagonists reduce morbidity and mortality among patients with heart failure and reduced ejection fraction, but their efficacy in those with heart failure and mildly reduced or preserved ejection fraction has not been established. Data regarding the efficacy and safety of the nonsteroidal mineralocorticoid receptor antagonist finerenone in patients with heart failure and mildly reduced or preserved ejection fraction are needed., Methods: In this international, double-blind trial, we randomly assigned patients with heart failure and a left ventricular ejection fraction of 40% or greater, in a 1:1 ratio, to receive finerenone (at a maximum dose of 20 mg or 40 mg once daily) or matching placebo, in addition to usual therapy. The primary outcome was a composite of total worsening heart failure events (with an event defined as a first or recurrent unplanned hospitalization or urgent visit for heart failure) and death from cardiovascular causes. The components of the primary outcome and safety were also assessed., Results: Over a median follow-up of 32 months, 1083 primary-outcome events occurred in 624 of 3003 patients in the finerenone group, and 1283 primary-outcome events occurred in 719 of 2998 patients in the placebo group (rate ratio, 0.84; 95% confidence interval [CI], 0.74 to 0.95; P = 0.007). The total number of worsening heart failure events was 842 in the finerenone group and 1024 in the placebo group (rate ratio, 0.82; 95% CI, 0.71 to 0.94; P = 0.006). The percentage of patients who died from cardiovascular causes was 8.1% and 8.7%, respectively (hazard ratio, 0.93; 95% CI, 0.78 to 1.11). Finerenone was associated with an increased risk of hyperkalemia and a reduced risk of hypokalemia., Conclusions: In patients with heart failure and mildly reduced or preserved ejection fraction, finerenone resulted in a significantly lower rate of a composite of total worsening heart failure events and death from cardiovascular causes than placebo.

Background: Inflammation is thought to be an important mechanism for the development and progression of obesity-related heart failure with preserved ejection fraction (HFpEF). In the STEP-HFpEF Program, once-weekly 2.4 mg semaglutide improved heart failure-related symptoms, physical limitations, and exercise function, reduced the levels of C-reactive protein (CRP), a biomarker of inflammation, and reduced body weight in participants with obesity-related HFpEF. However, neither the prevalence nor the clinical characteristics of patients who have various magnitudes of inflammation in the context of obesity-related HFpEF have been well described. Furthermore, whether the beneficial effects of semaglutide on the various HF efficacy endpoints in the STEP-HFpEF Program are modified by the baseline levels of inflammation has not been fully established. Finally, the relationship between weight reduction and changes in CRP across the STEP-HFpEF Program have not been fully defined., Objectives: This study sought to: 1) evaluate baseline characteristics and clinical features of patients with obesity-related HFpEF that have various levels of inflammation in the STEP-HFpEF Program; 2) determine if the effects of weekly semaglutide 2.4 mg vs placebo across all key outcomes are influenced by baseline levels of inflammation assessed by CRP levels; and 3) determine the relationship between change in CRP and weight loss in the STEP-HFpEF Program., Methods: This was a secondary analysis of pooled data from 2 international, double-blind, placebo-controlled, randomized trials (STEP-HFpEF and STEP-HFpEF DM). The outcomes were change in the dual primary endpoints (health status [measured by the Kansas City Cardiomyopathy Questionnaire-Clinical Summary Score (KCCQ-CSS)] and body weight) from baseline to 52 weeks according to baseline CRP levels. Additional efficacy endpoints included change in 6-minute walk distance (6MWD), a hierarchical composite endpoint that included death, heart failure events, and differences in the change in the KCCQ-CSS and 6MWD, and levels of CRP in semaglutide- vs placebo-treated patients. Patients were stratified into 3 categories based on baseline CRP levels (<2, ≥2 to <10, and ≥10 mg/L)., Results: In total, 1,145 patients were randomized, of which 71% of patients had evidence of inflammation (CRP ≥2 mg/L). At baseline, those with higher levels of inflammation were younger, were more likely to be female, and had higher body mass index, worse health status (KCCQ-CSS), and shorter 6MWD. Semaglutide vs placebo led to reductions in HF-related symptoms and physical limitations as well as body weight, and to improvements in 6MWD and the hierarchical composite endpoint that were consistent across baseline CRP categories (all P interaction nonsignificant). Semaglutide also reduced CRP to a greater extent than placebo regardless of baseline CRP levels (P interaction = 0.32). Change in CRP from baseline to 52 weeks was similar regardless of the magnitude of weight loss (P interaction = 0.91)., Conclusions: Inflammation is highly prevalent in obesity-related HFpEF. Semaglutide consistently improved HF-related symptoms, physical limitations, and exercise function, and reduced body weight across the categories of baseline CRP. Semaglutide also reduced inflammation, regardless of either baseline CRP or magnitude of weight loss during the trials.

Background: Obesity is associated with adverse cardiac remodeling and is a key driver for the development and progression of heart failure (HF). Once-weekly semaglutide (2.4 mg) has been shown to improve HF-related symptoms and physical limitations, body weight, and exercise function in patients with obesity-related heart failure with preserved ejection fraction (HFpEF), but the effects of semaglutide on cardiac structure and function in this population remain unknown., Objectives: In this echocardiography substudy of the STEP-HFpEF Program, we evaluated treatment effects of once-weekly semaglutide (2.4 mg) vs placebo on cardiac structure and function., Methods: Echocardiography at randomization and 52 weeks was performed in 491 of 1,145 participants (43%) in the STEP-HFpEF Program (pooled STEP-HFpEF [Semaglutide Treatment Effect in People with Obesity and HFpEF] and STEP-HFpEF DM [Semaglutide Treatment Effect in People with Obesity, HFpEF, and Type 2 Diabetes] trials). The prespecified primary outcome was change in left atrial (LA) volume, with changes in other echocardiography parameters evaluated as secondary outcomes. Treatment effects of semaglutide vs placebo were assessed using analysis of covariance stratified by trial and body mass index, with adjustment for baseline parameter values., Results: Overall, baseline clinical and echocardiographic characteristics were balanced among those receiving semaglutide (n = 253) and placebo (n = 238). Between baseline and 52 weeks, semaglutide attenuated progression of LA remodeling (estimated mean difference [EMD] in LA volume, -6.13 mL; 95% CI: -9.85 to -2.41 mL; P = 0.0013) and right ventricular (RV) enlargement (EMD in RV end-diastolic area: -1.99 cm 2 ; 95% CI: -3.60 to -0.38 cm 2 ; P = 0.016; EMD in RV end-systolic area: -1.41 cm 2 ; 95% CI: -2.42 to -0.40] cm 2 ; P = 0.0064) compared with placebo. Semaglutide additionally improved E-wave velocity (EMD: -5.63 cm/s; 95% CI: -9.42 to -1.84 cm/s; P = 0.0037), E/A (early/late mitral inflow velocity) ratio (EMD: -0.14; 95% CI: -0.24 to -0.04; P = 0.0075), and E/e' (early mitral inflow velocity/early diastolic mitral annular velocity) average (EMD: -0.79; 95% CI: -1.60 to 0.01; P = 0.05). These associations were not modified by diabetes or atrial fibrillation status. Semaglutide did not significantly affect left ventricular dimensions, mass, or systolic function. Greater weight loss with semaglutide was associated with greater reduction in LA volume (P interaction  = 0.033) but not with changes in E-wave velocity, E/e' average, or RV end-diastolic area., Conclusions: In the STEP-HFpEF Program echocardiography substudy, semaglutide appeared to improve adverse cardiac remodeling compared with placebo, further suggesting that treatment with semaglutide may be disease modifying among patients with obesity-related HFpEF.

Background: Obesity is a key factor in the development and progression of both heart failure with preserved ejection fraction (HFpEF) and atrial fibrillation (AF). In the STEP-HFpEF Program (comprising the STEP-HFpEF [Research Study to Investigate How Well Semaglutide Works in People Living With Heart Failure and Obesity] and STEP-HFpEF DM [Research Study to Look at How Well Semaglutide Works in People Living With Heart Failure, Obesity and Type 2 Diabetes] trials), once-weekly semaglutide 2.4 mg improved HF-related symptoms, physical limitations, and exercise function and reduced body weight in patients with obesity-related HFpEF. Whether the effects of semaglutide in this patient group differ in participants with and without AF (and across various AF types) has not been fully examined., Objectives: The goals of this study were: 1) to evaluate baseline characteristics and clinical features of patients with obesity-related HFpEF with and without a history of AF; and 2) to determine if the efficacy of semaglutide across all key trial outcomes are influenced by baseline history of AF (and AF types) in the STEP-HFpEF Program., Methods: This was a secondary analysis of pooled data from the STEP-HFpEF and STEP-HFpEF DM trials. Patients with heart failure, left ventricular ejection fraction ≥45%, body mass index ≥30 kg/m 2 , and Kansas City Cardiomyopathy Questionnaire-Clinical Summary Score (KCCQ-CSS) <90 points were randomized 1:1 to receive once-weekly semaglutide 2.4 mg or matching placebo for 52 weeks. Dual primary endpoints (change in KCCQ-CSS and percent change in body weight), confirmatory secondary endpoints (change in 6-minute walk distance; hierarchical composite endpoint comprising all-cause death, HF events, thresholds of change in KCCQ-CSS, and 6-minute walk distance; and C-reactive protein [CRP]), and exploratory endpoint (change in N-terminal pro-B-type natriuretic peptide [NT-proBNP]) were examined according to investigator-reported history of AF (yes/no). Responder analyses examined the proportions of patients who experienced a ≥5-, ≥10, ≥15, and ≥20-point improvement in KCCQ-CSS per history of AF., Results: Of the 1,145 participants, 518 (45%) had a history of AF (40% paroxysmal, 24% persistent AF, and 35% permanent AF) and 627 (55%) did not. Participants with (vs without) AF were older, more often male, had higher NT-proBNP levels, included a higher proportion of those with NYHA functional class III symptoms, and used more antithrombotic therapies, beta-blockers, and diuretics. Semaglutide led to larger improvements in KCCQ-CSS (11.5 points [95% CI: 8.3-14.8] vs 4.3 points [95% CI: 1.3-7.2]; P interaction = 0.001) and the hierarchal composite endpoint (win ratio of 2.25 [95% CI: 1.79-2.83] vs 1.30 [95% CI: 1.06-1.59]; P interaction < 0.001) in participants with AF vs without AF, respectively. The proportions of patients receiving semaglutide vs those receiving placebo experiencing ≥5-, ≥10-, ≥15-, and ≥20-point improvement in KCCQ-CSS were also higher in those with (vs without) AF (all P interaction values <0.05). Semaglutide consistently reduced CRP, NT-proBNP, and body weight regardless of AF status (all P interaction values not significant). There were fewer serious adverse events and serious cardiac disorders in participants treated with semaglutide vs placebo irrespective of AF history., Conclusions: In the STEP-HFpEF Program, AF was observed in nearly one-half of patients with obesity-related HFpEF and was associated with several features of more advanced HF. Treatment with semaglutide led to significant improvements in HF-related symptoms, physical limitations, and exercise function, as well as reductions in weight, CRP, and NT-proBNP in people with and without AF and across AF types. The magnitude of semaglutide-mediated improvements in HF-related symptoms and physical limitations was more pronounced in those with AF vs without AF at baseline.

Background: Wearable accelerometers can quantify the frequency and intensity of physical activity during everyday life and may provide complementary data to established functional outcome measures on the effect of heart failure therapies on functional limitations., Methods: In a voluntary substudy of the DETERMINE trials (Dapagliflozin Effect on Exercise Capacity Using a 6-Minute Walk Test in Patients With Heart Failure), patients wore a waist-worn triaxial accelerometer for as long as possible (ideally for 24 h/d for 7 days) at 3 points during the trial, between the screening visit and randomization (baseline data), and during weeks 8 and 14 to 16. Accelerometer outcomes included the change from baseline to week 16 in the total number of steps, time spent in light-to-vigorous physical activity, time spent in moderate-to-vigorous physical activity, movement intensity during walking, number of vector magnitude units' and total activity counts., Results: Adequate baseline and week 16 accelerometer data were available for 211 of 817 (26%) randomized patients (defined as ≥10 hours of wear time for ≥3 days). Dapagliflozin had a favorable effect on the mean change from baseline at 16 weeks in the number of steps (between-group difference, 778 [95% CI, 240-1315]), time spent in moderate-to-vigorous physical activity (0.16 [95% CI, 0.03-0.29] hours), and in the mean vector magnitude units (25 [95% CI, 0.1-49] counts per minute). There were no between-group differences in the other accelerometer outcomes of interest., Conclusions: In this exploratory analysis of the DETERMINE trials, dapagliflozin had a beneficial effect on selected accelerometer-based measures of physical activity in patients with heart failure across the entire left ventricular ejection fraction spectrum, yet did not improve 6-minute walk distance, as previously reported. These data suggest that accelerometer-based measurements of everyday activity may provide complementary information to 6-minute walk distance and identify beneficial effects of treatment not detected by 6-minute walk distance., Registration: URL: https://www.clinicaltrials.gov; Unique identifiers: NCT03877237 and NCT03877224., Competing Interests: Dr Docherty’s employer, the University of Glasgow, has been remunerated by AstraZeneca for his work on clinical trials; he has received speaker fees from AstraZeneca, Boehringer Ingelheim, Pharmacosmos, Translational Medical Academy, and Radcliffe Cardiology; has served on Advisory Boards for Us2.ai and holds stock in the company; has served on an advisory board and served on a clinical end point committee for Bayer AG; has performed consultancy for FIRE-1; and has received research grant support (paid to his institution) from AstraZeneca, Roche, Novartis, and Boehringer Ingelheim.

Importance: Elevated serum uric acid (SUA) level may contribute to endothelial dysfunction; therefore, SUA is an attractive target for heart failure with preserved ejection fraction (HFpEF). However, to the authors' knowledge, no prior randomized clinical trials have evaluated SUA lowering in HFpEF., Objective: To investigate the efficacy and safety of the novel urate transporter-1 inhibitor, verinurad, in patients with HFpEF and elevated SUA level., Design, Setting, and Participants: This was a phase 2, double-blind, randomized clinical trial (32-week duration) conducted from May 2020 to April 2022. The study took place at 59 centers in 12 countries and included patients 40 years and older with HFpEF and SUA level greater than 6 mg/dL. Data were analyzed from August 2022 to May 2024., Interventions: Eligible patients were randomized 1:1:1 to once-daily, oral verinurad, 12 mg, plus allopurinol, 300 mg; allopurinol, 300 mg, monotherapy; or placebo for 24 weeks after an 8-week titration period. Allopurinol was combined with verinurad to prevent verinurad-induced urate nephropathy, and the allopurinol monotherapy group was included to account for allopurinol effects in the combination therapy group. All patients received oral colchicine, 0.5 to 0.6 mg, daily for the first 12 weeks after randomization., Main Outcomes and Measures: Key end points included changes from baseline to week 32 in peak oxygen uptake (VO2), Kansas City Cardiomyopathy Questionnaire total symptom score (KCCQ-TSS), and SUA level; and safety/tolerability (including adjudicated cardiovascular events)., Results: Among 159 randomized patients (53 per treatment group; median [IQR] age, 71 [40-86] years; 103 male [65%]) with median (IQR) N-terminal pro-brain natriuretic peptide level of 527 (239-1044) pg/mL and SUA level of 7.5 (6.6-8.4) mg/dL, verinurad plus allopurinol (mean change, -59.6%; 95% CI, -64.4% to -54.2%) lowered SUA level to a greater extent than allopurinol (mean change, -37.6%; 95% CI, -45.3% to -28.9%) or placebo (mean change, 0.8%; 95% CI, -11.8% to 15.2%; P < .001). Changes in peak VO2 (verinurad plus allopurinol, 0.27 mL/kg/min; 95% CI, -0.56 to 1.10 mL/kg/min; allopurinol, -0.17 mL/kg/min; 95% CI, -1.03 to 0.69 mL/kg/min; placebo, 0.37 mL/kg/min; 95% CI, -0.45 to 1.19 mL/kg/min) and KCCQ-TSS (verinurad plus allopurinol, 4.3; 95% CI, 0.3-8.3; allopurinol, 4.5; 95% CI, 0.3-8.6; placebo, 1.2; 95% CI, -3.0 to 5.3) were similar across groups. There were no adverse safety signals. Deaths or cardiovascular events occurred in 3 patients (5.7%) in the verinurad plus allopurinol group, 8 patients (15.1%) in the allopurinol monotherapy group, and 6 patients (11.3%) in the placebo group., Conclusions and Relevance: Results of this randomized clinical trial show that despite substantial SUA lowering, verinurad plus allopurinol did not result in a significant improvement in peak VO2 or symptoms compared with allopurinol monotherapy or placebo in HFpEF., Trial Registration: ClinicalTrials.gov Identifier: NCT04327024.

Background: Mineralocorticoid receptor antagonists (MRAs) reduce hospitalisations and death in patients with heart failure and reduced ejection fraction (HFrEF), but the benefit in patients with heart failure and mildly reduced ejection fraction (HFmrEF) or heart failure and preserved ejection fraction (HFpEF) is unclear. We evaluated the effect of MRAs in four trials that enrolled patients with heart failure across the range of ejection fraction., Methods: This is a prespecified, individual patient level meta-analysis of the RALES (spironolactone) and EMPHASIS-HF (eplerenone) trials, which enrolled patients with HFrEF, and of the TOPCAT (spironolactone) and FINEARTS-HF (finerenone) trials, which enrolled patients with HFmrEF or HFpEF. The primary outcome of this meta-analysis was a composite of time to first hospitalisation for heart failure or cardiovascular death. We also estimated the effect of MRAs on components of this composite, total (first or repeat) heart failure hospitalisations (with and without cardiovascular deaths), and all-cause death. Safety outcomes were also assessed, including serum creatinine, estimated glomerular filtration rate, serum potassium, and systolic blood pressure. An interaction between trials and treatment was tested to examine the heterogeneity of effect in these populations. This study is registered with PROSPERO, CRD42024541487., Findings: 13 846 patients were included in the four trials. MRAs reduced the risk of cardiovascular death or heart failure hospitalisation (hazard ratio 0·77 [95% CI 0·72-0·83]). There was a statistically significant interaction by trials and treatment (p for interaction=0·0012) due to the greater efficacy in HFrEF (0·66 [0·59-0·73]) compared with HFmrEF or HFpEF (0·87 [0·79-0·95]). We observed significant reductions in heart failure hospitalisation in the HFrEF trials (0·63 [0·55-0·72]) and the HFmrEF or HFpEF trials (0·82 [0·74-0·91]). The same pattern was observed for total heart failure hospitalisations with or without cardiovascular death. Cardiovascular death was reduced in the HFrEF trials (0·72 [0·63-0·82]) but not in the HFmrEF or HFpEF trials (0·92 [0·80-1·05]). All-cause death was also reduced in the HFrEF trials (0·73 [0·65-0·83]) but not in the HFmrEF or HFpEF trials (0·94 [0·85-1·03]). With an MRA, the risk of hyperkalaemia was doubled compared with placebo (odds ratio 2·27 [95% CI 2·02-2·56]), but the incidence of serious hyperkalaemia (serum potassium >6·0 mmol/L) was low (2·9% vs 1·4%); the risk of hypokalaemia (potassium <3·5 mmol/L) was halved (0·51 [0·45-0·57]; 7% vs 14%)., Interpretation: Steroidal MRAs reduce the risk of cardiovascular death or heart failure hospitalisation in patients with HFrEF and non-steroidal MRAs reduce this risk in patients with HFmrEF or HFpEF., Funding: None., Competing Interests: Declaration of interests PSJ reports speakers fees from AstraZeneca, Novartis, Alkem Metabolics, ProAdWise Communications, and Sun Pharmaceuticals; advisory board fees from AstraZeneca, Boehringer Ingelheim, and Novartis; and research funding from AstraZeneca, Boehringer Ingelheim, Analog Devices, and Roche Diagnostics; and is a director of Global Clinical Trial Partners.

Given expanding studies in epidemiology and disease-oriented human studies offering hundreds of associations between the human "ome" and disease, prioritizing molecules relevant to disease mechanisms among this growing breadth is important. Here, we link the circulating proteome to human heart failure (HF) propensity (via echocardiographic phenotyping and clinical outcomes) across the lifespan, demonstrating key pathways of fibrosis, inflammation, metabolism, and hypertrophy. We observe a broad array of genes encoding proteins linked to HF phenotypes and outcomes in clinical populations dynamically expressed at a transcriptional level in human myocardium during HF and cardiac recovery (several in a cell-specific fashion). Many identified targets do not have wide precedent in large-scale genomic discovery or human studies, highlighting the complementary roles for proteomic and tissue transcriptomic discovery to focus epidemiological targets to those relevant in human myocardium for further interrogation., Competing Interests: Declaration of interests S.G.D. is a consultant for Abbott, and S.G.D. and K.J.L. have industry research support from Novartis.

Background and Aims: In the STEP-HFpEF trial programme, treatment with semaglutide resulted in multiple beneficial effects in patients with obesity-related heart failure with preserved ejection fraction (HFpEF). Efficacy may vary according to baseline diuretic use, and semaglutide treatment could modify diuretic dose., Methods: In this pre-specified analysis of pooled data from the STEP-HFpEF and STEP-HFpEF-DM trials (n = 1145), which randomized participants with HFpEF and body mass index ≥ 30 kg/m2 to once weekly semaglutide 2.4 mg or placebo for 52 weeks, we examined whether efficacy and safety endpoints differed by baseline diuretic use, as well as the effect of semaglutide on loop diuretic use and dose changes over the 52-week treatment period., Results: At baseline, across no diuretic (n = 220), non-loop diuretic only (n = 223), and loop diuretic [<40 (n = 219), 40 (n = 309), and >40 (n = 174) mg/day furosemide equivalents] groups, there was progressively higher prevalence of hypertension and atrial fibrillation; and greater severity of obesity and heart failure. Over 52 weeks of treatment, semaglutide had a consistent beneficial effect on change in body weight across diuretic use categories (adjusted mean difference vs. placebo ranged from -8.8% [95% confidence interval (CI) -10.3, -6.3] to -6.9% [95% CI -9.1, -4.7] from no diuretics to the highest loop diuretic dose category; interaction P = .39). Kansas City Cardiomyopathy Questionnaire clinical summary score improvement was greater in patients on loop diuretics compared to those not on loop diuretics (adjusted mean difference vs. placebo: +9.3 [6.5; 12.1] vs. +4.7 points [1.3, 8.2]; P = .042). Semaglutide had consistent beneficial effects on all secondary efficacy endpoints (including 6 min walk distance) across diuretic subgroups (interaction P = .24-.92). Safety also favoured semaglutide vs. placebo across the diuretic subgroups. From baseline to 52 weeks, loop diuretic dose decreased by 17% in the semaglutide group vs. a 2.4% increase in the placebo group (P < .0001). Semaglutide (vs. placebo) was more likely to result in loop diuretic dose reduction (odds ratio [OR] 2.67 [95% CI 1.70, 4.18]) and less likely dose increase (OR 0.35 [95% CI 0.23, 0.53]; P < .001 for both) from baseline to 52 weeks., Conclusions: In patients with obesity-related HFpEF, semaglutide improved heart failure-related symptoms and physical limitations across diuretic use subgroups, with more pronounced benefits among patients receiving loop diuretics at baseline. Reductions in weight and improvements in exercise function with semaglutide vs. placebo were consistent in all diuretic use categories. Semaglutide also led to a reduction in loop diuretic use and dose between baseline and 52 weeks., Clinical Trial Registration: NCT04788511 and NCT04916470., (© The Author(s) 2024.

Background: Heart failure with mildly reduced or preserved ejection fraction (hereafter referred to as HFpEF) is the most common type of heart failure and is associated with a high risk of hospitalisation and death, especially in patients with overweight, obesity, or type 2 diabetes. In the STEP-HFpEF and STEP-HFpEF DM trials, semaglutide improved heart failure-related symptoms and physical limitations in participants with HFpEF. Whether semaglutide also reduces clinical heart failure events in this group remains to be established., Methods: We conducted a post-hoc pooled, participant-level analysis of four randomised, placebo-controlled trials (SELECT, FLOW, STEP-HFpEF, and STEP-HFpEF DM) to examine the effects of once-weekly subcutaneous semaglutide (2·4 mg in SELECT, STEP-HFpEF, and STEP-HFpEF DM; 1·0 mg in FLOW) on heart failure events. The STEP-HFpEF and STEP-HFpF DM trials enrolled participants with obesity-related HFpEF, the SELECT trial enrolled participants with atherosclerotic cardiovascular disease and overweight or obesity, and the FLOW trial enrolled participants with type 2 diabetes and chronic kidney disease. Hence, for this analysis, we include all participants from the STEP-HFpEF trials and those with an investigator-reported history of HFpEF from SELECT and FLOW. The main outcomes for this analysis were the composite endpoint of time to cardiovascular death or first worsening heart failure event (defined as hospitalisation or urgent visit due to heart failure), time to first worsening heart failure event, and time to cardiovascular death. Efficacy and safety endpoints were analysed with the full analysis set (ie, all participants randomly assigned to treatment, according to the intention-to-treat principle). The SELECT, FLOW, STEP-HFpEF, and STEP-HFpEF DM trials are registered at ClinicalTrials.gov, NCT03574597, NCT03819153, NCT04788511, and NCT04916470, respectively, and all are complete., Findings: Across the four trials, 3743 (16·8%) of 22 282 participants had a history of HFpEF (1914 assigned to semaglutide and 1829 assigned to placebo). In this group of participants with HFpEF, semaglutide reduced the risk of the combined endpoint of cardiovascular death or heart failure events (103 [5·4%] of 1914 in the semaglutide group had events vs 138 [7·5%] of 1829 in the placebo group; hazard ratio [HR] 0·69 [95% CI 0·53-0·89]; p=0·0045). Semaglutide also reduced the risk of worsening heart failure events (54 [2·8%] vs 86 [4·7%]; HR 0·59 [0·41-0·82]; p=0·0019). No significant effect on cardiovascular death alone was seen (59 [3·1%] vs 67 [3·7%]; HR 0·82 [0·57-1·16]; p=0·25). A lower proportion of patients treated with semaglutide had serious adverse events than did those who were treated with placebo (572 [29·9%] vs 708 [38·7%])., Interpretation: In patients with HFpEF, semaglutide reduced the risk of the combined endpoint of cardiovascular death or worsening heart failure events, and worsening heart failure events alone, whereas its effect on cardiovascular death alone was not significant. These data support the use of semaglutide as an efficacious therapy to reduce the risk of clinical heart failure events in patients with HFpEF, for whom few treatment options are currently available., Funding: Novo Nordisk., Competing Interests: Declaration of interests MNK has served as a consultant for 35Pharma, Alnylam, Amgen, AstraZeneca, Bayer, Boehringer Ingelheim, Cytokinetics, Corcept Therapeutics, Dexcom, Eli Lilly, Esperion Therapeutics, Imbria Pharmaceuticals, Janssen, Lexicon Pharmaceuticals, Merck (Diabetes and Cardiovascular), Novo Nordisk, Pharmacosmos, Pfizer, Regeneron, scPharmaceuticals, Structure Therapeutics, Vifor Pharma, and Youngene Therapeutics; has served on a data monitoring board for Applied Therapeutics; has served on an advisory board for Alnylam, Amgen, Arrowhead Pharmaceuticals, AstraZeneca, Bayer, Boehringer Ingelheim, Corcept Therapeutics, Eli Lilly, Esperion Therapeutics, Merck (Diabetes and Cardiovascular), Novo Nordisk, and Sanofi; has received research grants from AstraZeneca, Boehringer Ingelheim, and Pfizer; holds stocks in Artera Health and Saghmos Therapeutics; has received honoraria from AstraZeneca, Boehringer Ingelheim, and Novo Nordisk; and has received support for data analyses from AstraZeneca and Vifor.

Metabolic comorbidities, such as obesity and diabetes, are associated with subclinical alterations in both cardiac structure/function and natriuretic peptides prior to the onset of heart failure (HF). Despite this, the exact metabolic pathways of cardiac dysfunction which precede HF are not well-defined. Among older individuals without HF in the Multi-Ethnic Study of Atherosclerosis (MESA), we evaluated the associations of 47 circulating metabolites measured by 1 H-NMR with echocardiographic measures of cardiac structure and function. We then evaluated associations of significant metabolites with circulating N-terminal pro-B-type natriuretic peptide (NT-proBNP). In a separate cohort, we evaluated differences between top metabolites in patients with HF with preserved ejection fraction (HFpEF) and comorbidity-matched controls. Genetic variants associated with top metabolites (mQTLs) were then related to echocardiographic measures and NT-proBNP. Among 3440 individuals with metabolic and echocardiographic data in MESA (62 ± 10 years, 52% female, 38% White), 10 metabolites broadly reflective of glucose and amino acid metabolism were associated with at least 1 measure of cardiac structure or function. Of these 10 metabolites, 4 (myo-inositol, glucose, dimethylsulfone, carnitine) were associated with higher NT-proBNP and 2 (d-mannose, acetone) were associated with lower NT-proBNP. In a separate cohort, patients with HFpEF had higher circulating myo-inositol levels compared with comorbidity-matched controls. Genetic analyses revealed that 1 of 6 known myo-inositol mQTLs conferred risk of higher NT-proBNP. In conclusion, metabolomic profiling identifies several novel metabolites associated with cardiac dysfunction in a cohort at high risk for HF, revealing pathways potentially relevant to future HF risk., (© 2024.

Background: Heart failure with preserved ejection fraction (HFpEF) is a heterogeneous syndrome that may emerge from overlapping systemic processes associated with comorbidities. We assessed whether unique clusters of circulating proteins are associated with specific clinical characteristics and functional status at baseline and follow-up in a well-phenotyped cohort of patients with HFpEF., Methods: We evaluated 368 proteins associated with cardiovascular disease and inflammation in prerandomization blood samples from 763 VITALITY-HFpEF (Vericiguat to Improve Physical Functioning in Daily Living Activities of Patients With HFpEF) participants who had a left ventricular ejection fraction ≥45% and a heart failure decompensation event within 6 months. Proteins were clustered, and their associations with clinical characteristics, baseline, and 24-week functional outcomes (Kansas City Cardiomyopathy Questionnaire Physical Limitation Score, 6-minute walk distance [6MWD], and Fried frailty phenotype) were estimated with linear regression. Elastic net regression was used to derive a proteomic summary composite to predict changes in 24-week functional outcomes., Results: Four unique protein clusters were identified, containing 24, 66, 197, and 81 proteins. At baseline, 2 protein clusters with the hub proteins caspase-3 and Dickkopf-related protein 1 were associated with increased frailty, whereas the cluster with tumor necrosis factor receptor 1 as a hub protein was associated with lower Kansas City Cardiomyopathy Questionnaire Physical Limitation Score and shorter 6MWD. By contrast, the cluster with protein C as a hub protein was associated with less frailty and longer a 6MWD. The 24-week increase in 6MWD was negatively correlated with the protein cluster with caspase-3; the protein C cluster was correlated with less frailty at 24 weeks. The baseline proteomic summary composite predicted observed changes in Kansas City Cardiomyopathy Questionnaire Physical Limitation Score and 6MWD at 24 weeks (r=0.42 and 0.30; P <0.001 for both)., Conclusions: Proteomics differentiate specific baseline functional traits associated with HFpEF and may facilitate phenotyping in a heterogeneous disease. These proteins also provide insights into the diverse pathophysiology of HFpEF and which patients may improve functional status during follow-up., Registration: URL: https://www.clinicaltrials.gov; Unique identifier: NCT03547583., Competing Interests: Dr deFilippi has received research funding to Inova from Abbott Diagnostics, Roche Diagnostics, Siemens Healthineers, and Ortho Diagnostics and consults for FujiRebio, Roche Diagnostics, Siemens Healthineers, and Ortho Diagnostics.

Background: Metabolic dysfunction associated steatotic liver disease (MASLD) has been linked to heart failure with preserved ejection fraction (HFpEF). We sought to understand association between individuals with amounts of liver adiposity greater than would be predicted by their body mass index (BMI) in order to understand whether this disproportionate liver fat (DLF) represents a proxy of metabolic risk shared between liver and heart disease., Methods: We studied 2,932 participants in the Multi-Ethnic Study of Atherosclerosis (MESA) who received computed tomography (CT) measurements of hepatic attenuation. Quartiles of DLF were compared and multivariable linear regression was performed to evaluate the association of DLF with clinical, echocardiographic, and quality of life metrics., Results: Compared to the lowest quartile of DLF, individuals in the highest quartile of DLF were more likely to be male (52.0% vs 47.1%, P < .001), less likely to be Black or African American (14.8 % vs 38.1% P < .001), have higher rates of dysglycemia (31.9% vs 16.6%, P < .001) and triglycerides (140 [98.0, 199.0] vs 99.0 [72.0, 144.0] mg/dL, P > .001). These individuals had lower global longitudinal strain (-0.13 [-0.25, -0.02], P = .02), stroke volumes (-1.05 [-1.76, -0.33], P < .01), lateral e' velocity (-0.10 [-0.18, -0.02], P = .02), and 6-minute walk distances (-4.25 [-7.62 to -0.88], P = .01)., Conclusion: DLF is associated with abnormal metabolic profiles and ventricular functional changes known to be associated with HFpEF and may serve as an early metric to assess for those that may progress to clinical HFpEF., Competing Interests: Declaration of competing interest The authors have no conflicts of interest to declare., (Copyright © 2024 Elsevier Inc.

Background: A common genetic variant of ICAM1 among African-American individuals (rs5491; p.K56M) is associated with heart failure (HF) hospitalization, but whether this risk is specific to heart failure with preserved ejection fraction (HFpEF) remains unclear. Older women are at high risk for HFpEF, and the relationship between rs5491 and HFpEF across the age spectrum is unknown., Objectives: This study assessed risk of HF and its subtypes conferred by ICAM1 p.K56M (rs5491)., Methods: Associations of rs5491 with risk of HF and its subtypes were estimated among African American individuals in WHI (Women's Health Initiative). The study evaluated whether the association between rs5491 and HF hospitalizations was modified by baseline age. Subsequently, African-American women in WHI and MESA (Multi-Ethnic Study of Atherosclerosis) were pooled and analyses were repeated., Results: Among 8,401 women in WHI, the minor allele frequency of rs5491 was 20.7%, and 731 HF hospitalizations occurred over 19.2 years. The rs5491 variant was not associated with HF or its subtypes across WHI. Interaction analyses suggested that age as a continuous variable modified the association of rs5491 with HFpEF hospitalization (interaction P = 0.04). Upon categorizing women into age decades, rs5491 conferred increased risk of HFpEF among women ≥70 years (HR per additional rs5491 allele: 1.82 [95% CI: 1.25-2.65]; P = 0.002) but was not associated with HFpEF risk among women <70 years. Pooling African-American women in WHI (n = 8,401) and MESA (n = 856) demonstrated that the effect modification by age on the association of rs5491 with HFpEF became more significant (interaction P = 0.009), with consistent HFpEF risk effect estimates among women ≥70 years., Conclusions: ICAM1 p.K56M (rs5491) is associated with HFpEF among African-American women ≥70 years., Competing Interests: Funding Support and Author Disclosures This work was supported by grants KL2TR001424 from the National Center for Advancing Translational Sciences, U.S. NIH (National Institutes of Health).

Aims: Compared with those without obesity, patients with obesity-related heart failure with preserved ejection fraction (HFpEF) have worse symptoms, haemodynamics, and outcomes. Current weight loss strategies (diet, drug, and surgical) work through decreased energy intake rather than increased expenditure and cause significant loss of skeletal muscle mass in addition to adipose tissue. This may have adverse implications for patients with HFpEF, who already have reduced skeletal muscle mass and function and high rates of physical frailty. Mitochondrial uncoupling agents may have unique beneficial effects by producing weight loss via increased catabolism rather than reduced caloric intake, thereby causing loss of adipose tissue while sparing skeletal muscle. HU6 is a controlled metabolic accelerator that is metabolized to the mitochondrial uncoupling agent 2,4-dinotrophenol. HU6 selectively increases carbon oxidation from fat and glucose while also decreasing toxic reactive oxygen species (ROS) production. In addition to sparing skeletal muscle loss, HU6 may have other benefits relevant to obesity-related HFpEF, including reduced specific tissue depots contributing to HFpEF; improved glucose utilization; and reduction in systemic inflammation via both decreased ROS production from mitochondria and decreased cytokine elaboration from excess, dysfunctional adipose., Methods: We describe the rationale and design of HuMAIN-HFpEF, a Phase 2a randomized, double-blind, placebo-controlled, dose-titration, parallel-group trial in patients with obesity-related HFpEF to evaluate the effects of HU6 on weight loss, body composition, exercise capacity, cardiac structure and function, metabolism, and inflammation, and identify optimal dosage for future Phase 3 trials., Conclusions: HuMAIN will test a promising novel agent for obesity-related HFpEF., (© 2024 The Author(s).

Background: There is a little evidence regarding long-term safety and efficacy for atrial shunt devices in heart failure (HF)., Methods: The REDUCE LAP-HF I (n = 44) and II (n = 621) trials (RCT-I and -II) were multicenter, randomized, sham-controlled trials of patients with HF and ejection fraction >40%. Outcome data were analyzed from RCT-I, a mechanistic trial with 5-year follow-up, and RCT-II, a pivotal trial identifying a responder group (n = 313) defined by exercise PVR <1.74 WU and no cardiac rhythm management device with 3-year follow-up., Results: At 5 years in RCT I, there were no differences in cardiovascular (CV) mortality, HF events, embolic stroke, or new-onset atrial fibrillation between groups. After 3 years in RCT II, there was no difference in the primary outcome (hierarchical composite of CV mortality, stroke, HF events, and KCCQ) between shunt and sham in the overall trial. Compared to sham, those with responder characteristics in RCT-II had a better outcome with shunt (win ratio 1.6 [95% CI 1.2-2.2], P = .006; 44% reduction in HF events [shunt 9 vs. control 16 per 100 patient-years], P = .005; and greater improvement in KCCQ overall summary score [+17.9 ± 20.0 vs. +7.6 ± 20.4], P < .001), while nonresponders had significantly more HF events. Shunt treatment at 3 years was associated with a higher rate of ischemic stroke (3.2% vs. 0%, 95% CI 2%-6.1%, P = .032) and lower incidence of worsening kidney dysfunction (10.7% vs. 19.3%, P = .041)., Conclusions: With up to 5 years of follow up, adverse events were low in patients receiving atrial shunts. In the responder group, atrial shunt treatment was associated with a significantly lower HF event rate and improved KCCQ compared to sham through 3 years of follow-up., Gov Registration: NCT02600234, NCT03088033., Competing Interests: Conflict of Interest None., (Published by Elsevier Inc.)

Background: More women than men have heart failure with preserved ejection fraction (HFpEF)., Objectives: The purpose of this study was to assess baseline characteristics and treatment effect of semaglutide by sex across the STEP-HFpEF (Research Study to Investigate How Well Semaglutide Works in People Living With Heart Failure and Obesity) program., Methods: In a prespecified secondary analysis of pooled data from STEP-HFpEF and STEP-HFpEF DM (Research Study to Look at How Well Semaglutide Works in People Living With Heart Failure, Obesity and Type 2 Diabetes), patients with heart failure (HF), left ventricular ejection fraction ≥45%, body mass index ≥30 kg/m 2 , and Kansas City Cardiomyopathy Questionnaire Clinical Summary Score (KCCQ-CSS) <90 points were randomized 1:1 to once-weekly semaglutide 2.4 mg or matched placebo for 52 weeks. Dual primary endpoints (KCCQ-CSS change and percentage change in body weight) and confirmatory secondary endpoints (6-minute walking distance [6MWD] change; hierarchical composite endpoint comprising all-cause death, HF events, changes in KCCQ-CSS, and 6MWD; and C-reactive protein) were compared between sexes., Results: Of 1,145 patients, 570 (49.7%) were women. Women had higher body mass index, left ventricular ejection fraction, C-reactive protein, and worse HF symptoms, and were less likely to have atrial fibrillation or coronary artery disease vs men. Semaglutide improved KCCQ-CSS regardless of sex (mean difference in women +7.6 points [95% CI: 4.5-10.7 points]; men +7.5 points [95% CI: 4.3-10.6 points]; P interaction = 0.94) but reduced body weight more in women (mean difference in women -9.6% [95% CI: -10.9% to -8.4%]; men -7.2% [95% CI: -8.4% to -6.0%]; P interaction = 0.006). Semaglutide improved 6MWD (P interaction = 0.21) and the hierarchical composite endpoint (P interaction = 0.66) in both sexes. Fewer serious adverse events were reported with semaglutide vs placebo., Conclusions: In patients with obesity-related HFpEF, semaglutide 2.4 mg reduced body weight to a greater extent in women, and produced similar improvements in HF-related symptoms, physical limitations, and exercise function, regardless of sex.

Heart failure with preserved ejection fraction (HFpEF) accounts for nearly half of all heart failure cases and has a prevalence that is expected to rise with the growing ageing population. HFpEF is associated with significant morbidity and mortality. Specific HFpEF risk factors include age, diabetes, hypertension, obesity and atrial fibrillation. Haemodynamic contributions to HFpEF include changes in left ventricular structure, diastolic and systolic dysfunction, left atrial myopathy, pulmonary hypertension, right ventricular dysfunction, chronotropic incompetence, and vascular dysfunction. Inflammation, fibrosis, impaired nitric oxide signalling, sarcomere dysfunction, and mitochondrial and metabolic defects contribute to the cellular and molecular changes observed in HFpEF. HFpEF impacts multiple organ systems beyond the heart, including the skeletal muscle, peripheral vasculature, lungs, kidneys and brain. The diagnosis of HFpEF can be made in individuals with signs and symptoms of heart failure with abnormality in natriuretic peptide levels or evidence of cardiopulmonary congestion, facilitated by the use of HFpEF risk scores and additional imaging and testing with the exclusion of HFpEF mimics. Management includes initiation of guideline-directed medical therapy and management of comorbidities. Given the significant impact of HFpEF on quality of life, future research efforts should include a particular focus on how patients can live better with this disease., (© 2024.

Background: Obesity (body mass index ≥ 30 kg/m 2 ) is a major risk factor for heart failure with preserved ejection fraction (HFpEF) and affects most patients with HFpEF. Patients living with obesity may experience delays in HFpEF diagnosis and management. We aimed to understand the clinical journey of patients with obesity and HFpEF and the role of primary care providers (PCPs) in diagnosing and managing patients with both conditions., Methods: An anonymous, US population-based online survey was conducted in September 2020 among 114 patients with self-reported HFpEF and obesity and 200 healthcare providers, 61 of whom were PCPs who treat patients with HFpEF and obesity., Results: Half of patients (51%) with HFpEF reported waiting an average of 11 months to discuss their symptoms with a PCP; 11% then received their diagnosis from a PCP. PCPs initiated treatment and oversaw the management of HFpEF only 35% of the time, and 44% of PCPs discussed obesity treatment medication options with their patients. Only 20% of PCPs indicated they had received formal obesity management training, and 79% of PCPs indicated they would be interested in obesity management training and support., Conclusion: PCPs could play a valuable role in addressing obesity and referring patients with obesity and signs and symptoms of HFpEF to cardiologists. Increased awareness of HFpEF and its link to obesity may help PCPs more quickly identify and diagnose their patients with these conditions., (© 2024. The Author(s).)

Background: The REDUCE LAP-HF II (Reduce Elevated Left Atrial Pressure in Patients With Heart Failure II) trial found that, compared with a sham procedure, the Corvia Atrial Shunt did not improve outcomes in heart failure with preserved or mildly reduced ejection fraction. However, after 12-month follow-up, "responders" (peak-exercise pulmonary vascular resistance <1.74 WU and absence of a cardiac rhythm management device) were identified., Objectives: This study sought to determine: 1) the overall efficacy and safety of the atrial shunt vs sham control after 2 years of follow-up; and 2) whether the benefits of atrial shunting are sustained in responders during longer-term follow-up or are offset by adverse effects of the shunt., Methods: The study analyzed 2-year outcomes in the overall REDUCE LAP-HF II trial, as well as in responder and nonresponder subgroups. The primary endpoint was a hierarchical composite of cardiovascular death or nonfatal ischemic/embolic stroke, total heart failure events, and change in health status., Results: In 621 randomized patients, there was no difference between the shunt (n = 309) and sham (n = 312) groups in the primary endpoint (win ratio: 1.01 [95% CI: 0.82-1.24]) or its individual components at 2 years. Shunt patency at 24 months was 98% in shunt-treated patients. Cardiovascular mortality and nonfatal ischemic stroke were not different between the groups; however, major adverse cardiac events were more common in those patients assigned to the shunt compared with sham (6.9% vs 2.7%; P = 0.018). More patients randomized to the shunt had an increase in right ventricular volume of ≥30% compared with the sham control (39% vs 28%, respectively; P < 0.001), but right ventricular dysfunction was uncommon and not different between the treatment groups. In responders (n = 313), the shunt was superior to sham (win ratio: 1.36 [95% CI: 1.02-1.83]; P = 0.037, with 51% fewer HF events [incidence rate ratio: 0.49 [95% CI: 0.25-0.95]; P = 0.034]). In nonresponders (n = 265), atrial shunting was inferior to sham (win ratio: 0.73 [95% CI: 0.54-0.98])., Conclusions: At 2 years of follow-up in REDUCE LAP-HF II, there was no difference in efficacy between the atrial shunt and sham groups in the overall trial group. The potential clinical benefit identified in the responder group after 1 and 2 years of follow-up is currently being evaluated in the RESPONDER-HF (Re-Evaluation of the Corvia Atrial Shunt Device in a Precision Medicine Trial to Determine Efficacy in Mildly Reduced or Preserved Ejection Fraction Heart Failure) trial.

Background: Although some patients with heart failure (HF) with mildly reduced/preserved ejection fraction have low natriuretic peptide levels, there are no large-scale systematic studies of how common these individuals are or what happens to them., Objectives: The purpose of this study was to examine the proportion of patients in the I-PRESERVE (Irbesartan in Heart Failure with Preserved Ejection Fraction) trial with an N-terminal pro-B-type natriuretic peptide (NT-proBNP) level <125 pg/mL, their clinical characteristics, and outcomes., Methods: I- PRESERVE enrolled patients with symptomatic HF and a LVEF ≥45% but who did not have NT-proBNP or body mass index inclusion/exclusion criteria. Baseline NT-proBNP was measured after enrollment but not reported to investigators. The primary outcome in this analysis was the composite of cardiovascular death or HF hospitalization., Results: Overall, 808 of 3,480 patients (23.2%) had NT-proBNP <125 pg/mL. Patients with a low NT-proBNP were younger (68.6 years vs 72.6 years; P < 0.001), were less often men (36.1% vs 40.9%; P = 0.015), and had a higher body mass index (48.4% vs 38.7% obese; P < 0.001) than those with a higher NT-proBNP level. Patients with a low NT-proBNP had less atrial fibrillation (8.5% vs 35.1%; P < 0.001), myocardial infarction, diabetes, chronic obstructive pulmonary disease, and anemia but better kidney function. Patients with a lower NT-proBNP level had less marked echocardiographic abnormalities and were less likely to experience cardiovascular death or HF hospitalization; adjusted HR: 0.35 (95% CI: 0.27-0.46; P < 0.001). However, health status was similarly impaired in patients with lower and higher NT-proBNP levels (median Minnesota Living with Heart Failure Questionnaire 43 vs 43; P = 0.95)., Conclusions: Almost one-quarter of patients with HF with mildly reduced/preserved ejection fraction had a low NT-proBNP level. Although these patients have a favorable prognosis, compared to those with a high NT-proBNP level, they have similarly impaired health status which should be a target for treatment.

Background: In the Semaglutide Treatment Effect in People with obesity and HFpEF (STEP-HFpEF) program, semaglutide improved heart failure (HF)-related symptoms, physical limitations, and exercise function, and reduced bodyweight in patients with obesity-related heart failure with preserved ejection fraction (HFpEF). Whether semaglutide improves functional status, as assessed by NYHA functional class, is unknown., Objectives: The goal of this study was to examine the effects of semaglutide on change in NYHA functional class over time. We also investigated the effects of semaglutide on HF-related symptoms, physical limitations, and bodyweight and other trial endpoints across baseline NYHA functional class categories., Methods: This was a prespecified analysis of pooled data from 2 international, double-blind, randomized trials (STEP-HFpEF and STEP-HFpEF type 2 diabetes [STEP-HFpEF DM], comprising the STEP-HFpEF program), which collectively randomized 1,145 participants with obesity-related HFpEF to once-weekly semaglutide 2.4 mg or placebo for 52 weeks. The outcome of interest for this analysis was the change in NYHA functional class (baseline to 52 weeks). We also investigated the effects of semaglutide on the dual primary, confirmatory secondary, and selected exploratory endpoints according to baseline NYHA functional class., Results: More semaglutide-treated than placebo-treated patients had an improvement in NYHA functional class (32.6% vs 21.5%, respectively; OR: 2.20 [95% CI: 1.62-2.99; P < 0.001]) and fewer semaglutide-treated patients experienced deterioration in NYHA functional class (2.09% vs 5.24%, respectively; OR: 0.36 [95% CI: 0.19-0.70; P = 0.003]) at 52 weeks. Semaglutide (vs placebo) improved the Kansas City Cardiomyopathy Questionnaire-Clinical Summary Score (KCCQ-CCS) across NYHA functional class categories; this was especially pronounced in those in NYHA functional classes III/IV (10.5 points [95% CI: 6.6-14.4 points]) vs NYHA functional class II (6.0 points [95% CI: 3.4-8.6 points]) (P interaction = 0.06). By contrast, the degree of reduction in bodyweight was similar with semaglutide vs placebo regardless of baseline NYHA functional class category (NYHA functional class II, -8.4% [95% CI: -9.4% to -7.3%]; NYHA functional classes III/IV, -8.3% [95% CI: -9.9% to -6.8%]; P interaction = 0.96). Semaglutide consistently improved 6-minute walking distance (6MWD), the hierarchical composite endpoint (death, HF events, differences in KCCQ-CSS, and 6MWD changes), and reduced C-reactive protein and N-terminal prohormone of brain natriuretic peptide across NYHA functional class categories (all P interactions = NS)., Conclusions: In patients with obesity-related HFpEF, fewer semaglutide-treated than placebo-treated patients had a deterioration, and more had an improvement, in NYHA functional class at 52 weeks. Semaglutide consistently improved HF-related symptoms, physical limitations, and exercise function, and reduced bodyweight and biomarkers of inflammation and congestion in all NYHA functional class categories.

Background: The glucagon-like peptide-1 receptor agonist, semaglutide, improved health status and reduced body weight in patients with obesity-related heart failure (HF) with preserved ejection fraction (HFpEF) in the STEP-HFpEF (Semaglutide Treatment Effect in People with Obesity and HFpEF) program. Whether benefits were due to mechanical unloading or effects on HF pathobiology is uncertain., Objectives: This study sought to determine if semaglutide 2.4 mg reduced N-terminal pro-B-type natriuretic peptide (NT-proBNP) in patients with obesity-related HFpEF and compare treatment responses by baseline NT-proBNP., Methods: This was a prespecified secondary analysis of pooled data from 2 double-blind, placebo-controlled, randomized trials (STEP-HFpEF [Research Study to Investigate How Well Semaglutide Works in People Living With Heart Failure and Obesity] and STEP-HFpEF DM [Research Study to Look at How Well Semaglutide Works in People Living With Heart Failure, Obesity and Type 2 Diabetes]) testing effects of semaglutide in patients with obesity-related HFpEF. The main outcomes were change in NT-proBNP at 52 weeks and change in the dual primary endpoints of Kansas City Cardiomyopathy Questionnaire Clinical Summary Score and body weight by baseline NT-proBNP., Results: In total, 1,145 patients were randomized. Semaglutide compared with placebo reduced NT-proBNP at 52 weeks (estimated treatment ratio: 0.82; 95% CI: 0.74-0.91; P = 0.0002). Improvements in health status were more pronounced in those with higher vs lower baseline NT-proBNP (estimated difference: tertile 1: 4.5 points, 95% CI: 0.8-8.2; tertile 2: 6.2 points, 95% CI: 2.4-10.0; tertile 3: 11.9 points, 95% CI: 8.1-15.7; P interaction = 0.02; baseline NT-proBNP as a continuous variable: P interaction = 0.004). Reductions in body weight were consistent across baseline NT-proBNP levels (P interaction = 0.21)., Conclusions: In patients with obesity-related HFpEF, semaglutide reduced NT-proBNP. Participants with higher baseline NT-proBNP had a similar degree of weight loss but experienced larger reductions in HF-related symptoms and physical limitations with semaglutide than those with lower NT-proBNP., Competing Interests: Funding Support and Author Disclosures The STEP-HFpEF program was funded by Novo Nordisk.

Objective: Splanchnic vasoconstriction augments transfer of blood volume from the abdomen into the thorax, which may increase filling pressures and hemodynamic congestion in patients with noncompliant hearts. Therapeutic interruption of splanchnic nerve activity holds promise to reduce hemodynamic congestion in patients with heart failure with preserved ejection fraction (HFpEF). Here we describe (1) the rationale and design of the first sham-controlled, randomized clinical trial of splanchnic nerve ablation for HFpEF and (2) the 12-month results of the lead-in (open-label) trial's participants., Methods: REBALANCE-HF is a prospective, multicenter, randomized, double-blinded, sham-controlled clinical trial of endovascular, transcatheter, right-sided greater splanchnic nerve ablation for volume management (SAVM) in patients with HFpEF. The primary objectives are to evaluate the safety and efficacy of SAVM and identify responder characteristics to inform future studies. The trial consists of an open-label lead-in phase followed by the randomized, sham-controlled phase. The primary efficacy endpoint is the reduction in pulmonary capillary wedge pressure (PCWP) at 1-month follow-up compared to baseline during passive leg raise and 20W exercise. Secondary and exploratory endpoints include health status (Kansas City Cardiomyopathy Questionnaire), 6-minute walk test distance, New York Heart Association class, and NTproBNP levels at 3, 6 and 12 months. The primary safety endpoint is device- or procedure-related serious adverse events at the 1-month follow-up., Results: The lead-in phase of the study, which enrolled 26 patients with HFpEF who underwent SAVM, demonstrated favorable safety outcomes and reduction in exercise PCWP at 1 month post-procedure and improvements in all secondary endpoints at 6 and 12 months of follow-up. The randomized phase of the trial (n = 44 SAVM; n = 46 sham) has completed enrollment, and follow-up is ongoing., Conclusion: REBALANCE-HF is the first sham-controlled randomized clinical trial of greater splanchnic nerve ablation in HFpEF. Initial 12-month open-label results are promising, and the results of the randomized portion of the trial will inform the design of a future pivotal clinical trial.

Aims: Type 2 diabetes (T2D) and heart failure (HF) frequently coexist, but whether clinical outcomes and treatment effects of sodium-glucose cotransporter 2 inhibitors (SGLT2i) vary in relation to background glucose-lowering therapy (GLT) in this population is uncertain., Methods and Results: DELIVER randomized patients with HF and left ventricular ejection fraction (LVEF) >40% to dapagliflozin or placebo. The primary outcome was a composite of worsening HF (HF hospitalization or urgent HF visit) or cardiovascular death. In this pre-specified analysis of participants with T2D, treatment effects were assessed by number and class of background GLT(s). Of 3150 participants with T2D at baseline, 22.9% were on no GLT, 36.5% were treated with 1 GLT, and 40.6% with ≥2 GLTs. During follow-up (median: 2.3 years), treatment benefits of dapagliflozin (vs. placebo) on the primary outcome were consistent irrespective of the number of background GLTs (0 GLTs: hazard ratio [HR] 0.71, 95% confidence interval [CI] 0.50-1.00; 1 GLT: HR 1.04, 95% CI 0.80-1.34; ≥2 GLTs: HR 0.71, 95% CI 0.56-0.90; p interaction  = 0.59). Similar findings were observed among participants with (HR 0.73, 95% CI 0.59-0.92) and without background metformin use (HR 0.89, 95% CI 0.72-1.11; p interaction  = 0.22) and in participants with (HR 0.89, 95% CI 0.69-1.16) and without background insulin use (HR 0.78, 95% CI 0.65-0.95; p interaction  = 0.45). Dapagliflozin was well-tolerated irrespective of the number of background GLTs., Conclusions: Dapagliflozin safely and consistently improved clinical outcomes among individuals with T2D and HF with LVEF >40% irrespective of the number and class of background GLTs, and the benefits were not influenced by concomitant metformin or insulin use. These data bolster contemporary guidelines supporting first-line SGLT2i among individuals with T2D and HF, irrespective of background GLT., (© 2024 The Authors.

Aim: Steroidal mineralocorticoid receptor antagonists (MRAs), spironolactone and eplerenone, are strongly recommended in the treatment of patients with chronic heart failure (HF) with reduced left ventricular ejection fraction (LVEF), but the balance of efficacy and safety in those with higher LVEF has not been well established. Broad use of steroidal MRAs has further been limited in part due to safety concerns around risks of hyperkalaemia, gynecomastia, and kidney dysfunction. These risks may be mitigated by the unique pharmacological properties of the non-steroidal MRA finerenone. The FINEARTS-HF trial is designed to evaluate the long-term efficacy and safety of the selective non-steroidal MRA finerenone among patients with HF with mildly reduced or preserved ejection fraction., Methods: FINEARTS-HF is a global, multicentre, event-driven randomized trial evaluating oral finerenone versus matching placebo in symptomatic patients with HF with LVEF ≥40%. Adults (≥40 years) with HF with New York Heart Association class II-IV symptoms, LVEF ≥40%, evidence of structural heart disease, and diuretic use for at least the previous 30 days were eligible. All patients required elevated natriuretic peptide levels: for patients in sinus rhythm, N-terminal pro-B-type natriuretic peptide (NT-proBNP) ≥300 pg/ml (or B-type natriuretic peptide [BNP] ≥100 pg/ml) were required, measured within 30 days (in those without a recent worsening HF event) or within 90 days (in those with a recent worsening HF event). Qualifying levels of NT-proBNP or BNP were tripled if a patient was in atrial fibrillation at screening. Estimated glomerular filtration rate <25 ml/min/1.73 m 2 or serum potassium >5.0 mmol/L were key exclusion criteria. Patients were enrolled irrespective of clinical care setting (whether hospitalized, recently hospitalized, or ambulatory). The primary endpoint is the composite of cardiovascular death and total (first and recurrent) HF events. The trial started on 14 September 2020 and has validly randomized 6001 participants across 37 countries. Approximately 2375 total primary composite events are targeted., Conclusions: The FINEARTS-HF trial will determine the efficacy and safety of the non-steroidal MRA finerenone in a broad population of hospitalized and ambulatory patients with HF with mildly reduced or preserved ejection fraction., Clinical Trial Registration: ClinicalTrials.gov NCT04435626 and EudraCT 2020-000306-29., (© 2024 The Authors.

Aims: To describe the baseline characteristics of participants in the FINEARTS-HF trial, contextualized with prior trials including patients with heart failure (HF) with mildly reduced and preserved ejection fraction (HFmrEF/HFpEF). The FINEARTS-HF trial is comparing the effects of the non-steroidal mineralocorticoid receptor antagonist finerenone with placebo in reducing cardiovascular death and total worsening HF events in patients with HFmrEF/HFpEF., Methods and Results: Patients with symptomatic HF, left ventricular ejection fraction (LVEF) ≥40%, estimated glomerular filtration rate ≥ 25 ml/min/1.73 m 2 , elevated natriuretic peptide levels and evidence of structural heart disease were enrolled and randomized to finerenone titrated to a maximum of 40 mg once daily or matching placebo. We validly randomized 6001 patients to finerenone or placebo (mean age 72 ± 10 years, 46% women). The majority were New York Heart Association functional class II (69%). The baseline mean LVEF was 53 ± 8% (range 34-84%); 36% of participants had a LVEF <50% and 64% had a LVEF ≥50%. The median N-terminal pro-B-type natriuretic peptide (NT-proBNP) was 1041 (interquartile range 449-1946) pg/ml. A total of 1219 (20%) patients were enrolled during or within 7 days of a worsening HF event, and 3247 (54%) patients were enrolled within 3 months of a worsening HF event. Compared with prior large-scale HFmrEF/HFpEF trials, FINEARTS-HF participants were more likely to have recent (within 6 months) HF hospitalization and greater symptoms and functional limitations. Further, concomitant medications included a larger percentage of sodium-glucose cotransporter 2 inhibitors and angiotensin receptor-neprilysin inhibitors than previous trials., Conclusions: FINEARTS-HF has enrolled a broad range of high-risk patients with HFmrEF and HFpEF. The trial will determine the safety and efficacy of finerenone in this population., (© 2024 The Authors.

Importance: Although the results of A Study to Evaluate the Corvia Medical Inc IASD System II to Reduce Elevated Left Atrial Pressure in Patients with Heart Failure (REDUCE LAP-HF II) trial were neutral overall, atrial shunt therapy demonstrated potential efficacy in responders (no latent pulmonary vascular disease and no cardiac rhythm management device). Post hoc analyses were conducted to evaluate the effect of shunt vs sham stratified by responder status., Objective: To evaluate the effect of atrial shunt vs sham control on cardiac structure/function in the overall study and stratified by responder status., Design, Setting, and Participants: This was a sham-controlled randomized clinical trial of an atrial shunt device in heart failure with preserved ejection fraction (HFpEF)/HF with mildly reduced EF (HFmrEF). Trial participants with evaluable echocardiography scans were recruited from 89 international medical centers. Data were analyzed from April 2023 to January 2024., Interventions: Atrial shunt device or sham control., Main Outcome Measures: Changes in echocardiographic measures from baseline to 1, 6, 12, and 24 months after index procedure., Results: The modified intention-to-treat analysis of the REDUCE LAP-HF II trial included 621 randomized patients (median [IQR] age, 72.0 [66.0-77.0] years; 382 female [61.5%]; shunt arm, 309 [49.8%]; sham control arm, 312 [50.2%]). Through 24 months, 212 of 217 patients (98%) in the shunt arm with evaluable echocardiograms had patent shunts. In the overall trial population, the shunt reduced left ventricular (LV) end-diastolic volume (mean difference, -5.65 mL; P <.001), left atrial (LA) minimal volume (mean difference, -2.8 mL; P =.01), and improved LV systolic tissue Doppler velocity (mean difference, 0.69 cm/s; P <.001) and LA emptying fraction (mean difference, 1.88 percentage units; P =.02) compared with sham. Shunt treatment also increased right ventricular (RV; mean difference, 9.58 mL; P <.001) and right atrial (RA; mean difference, 9.71 mL; P <.001) volumes but had no effect on RV systolic function, pulmonary artery pressure, or RA pressure compared with sham. In the shunt arm, responders had smaller increases in RV end-diastolic volume (mean difference, 5.71 mL vs 15.18 mL; interaction P =.01), RV end-systolic volume (mean difference, 1.58 mL vs 7.89 mL; interaction P =.002), and RV/LV ratio (mean difference, 0.07 vs 0.20; interaction P <.001) and larger increases in transmitral A wave velocity (mean difference, 5.08 cm/s vs -1.97 cm/s; interaction P =.02) compared with nonresponders randomized to the shunt, suggesting greater ability to accommodate shunted blood through the pulmonary circulation enabling LA unloading., Conclusions and Relevance: In this post hoc analysis of the REDUCE LAP-HF II trial, over 2 years of follow-up, atrial shunting led to reverse remodeling of left-sided chambers and increases in volume of right-sided chambers consistent with the shunt flow but no change in RV systolic function compared with sham. Changes in cardiac structure/function were more favorable in responders compared with nonresponders treated with the shunt, supporting the previously identified responder group hypothesis and mechanism, although further evaluation with longer follow-up is needed., Trial Registration: ClinicalTrials.gov Identifier: NCT03088033.

Background: Although sodium glucose co-transporter 2 inhibitors (SGLT2is) improve heart failure (HF)-related symptoms and outcomes in HF with preserved ejection fraction (HFpEF), underlying mechanisms remain unclear. In HF with reduced EF, dapagliflozin altered ketone and fatty acid metabolites vs placebo; however, metabolite signatures of SGLT2is have not been well elucidated in HFpEF., Objectives: The goal of this study was to assess whether SGLT2i treatment altered systemic metabolic pathways and their relationship to outcomes in HFpEF., Methods: Targeted profiling of 64 metabolites was performed from 293 participants in PRESERVED-HF (Dapagliflozin in PRESERVED Ejection Fraction Heart Failure), a 12-week, placebo-controlled trial of dapagliflozin. Linear regression assessed changes in metabolite factors defined by principal components analysis (PCA) with dapagliflozin vs placebo. The relationship between changes in metabolite factors with changes in study endpoints was also assessed., Results: The mean age was 70 ± 11 years, 58% were female, and 29% were Black. There were no significant differences in 12 PCA-derived metabolite factors between treatment arms, including metabolites reflecting ketone, fatty acid, or branched-chain amino acid (BCAA) pathways. Combining treatment arms, changes in BCAAs and branched-chain ketoacids were negatively associated with changes in N-terminal pro-B-type natriuretic peptide; changes in medium-/long-chain acylcarnitines were positively associated with changes in N-terminal pro-B-type natriuretic peptide and negatively associated with changes in 6-minute walk test distance; and changes in ketones were negatively associated with changes in weight, without treatment interaction., Conclusions: Leveraging targeted metabolomics in a placebo-controlled SGLT2i trial of HFpEF, dapagliflozin did not alter systemic metabolic as reflected by circulating metabolites, in contrast with reported effects in HF with reduced ejection fraction. Metabolite biomarkers reflecting BCAA, ketone, and fatty acid metabolism were associated with markers of disease severity, suggesting a role for potential novel treatment targets.

A hallmark of heart failure (HF), whether it presents itself during rest or periods of physical exertion, is the excessive elevation of intracardiac filling pressures at rest or with exercise. Many mechanisms contribute to the elevated intracardiac filling pressures, and notably, the concept of volume redistribution has gained attention as a cause of the elevated intracardiac filling pressures in patients with HF, particularly HF with preserved ejection fraction, who often present without symptoms at rest, with shortness of breath and fatigue appearing only during exertion. This phenomenon suggests cardiopulmonary system non-compliance and inappropriate volume distribution between the stressed and unstressed blood volume components. A substantial proportion of the intravascular blood volume is in the splanchnic vascular compartment in the abdomen. Preclinical and clinical investigations support the critical role of the sympathetic nervous system in modulating the capacitance and compliance of the splanchnic vascular bed via modulation of the greater splanchnic nerve (GSN). The GSN activation by stressors such as exercise causes excessive splanchnic vasoconstriction, which may contribute to the decompensation of chronic HF via volume redistribution from the splanchnic vascular bed to the central compartment. Accordingly, for example, GSN ablation for volume management has been proposed as a potential therapeutic intervention to increase unstressed blood volume. Here we provide a comprehensive review of the role of splanchnic circulation in the pathogenesis of HF and potential novel treatment options for redistributing blood volume to improve symptoms and prognosis in patients with HF., (Copyright © 2024 Elsevier Ltd.

Background: In the STEP-HFpEF (NCT04788511) and STEP-HFpEF DM (NCT04916470) trials, the GLP-1 receptor agonist semaglutide improved symptoms, physical limitations, bodyweight, and exercise function in people with obesity-related heart failure with preserved ejection fraction. In this prespecified pooled analysis of the STEP-HFpEF and STEP-HFpEF DM trials, we aimed to provide a more definitive assessment of the effects of semaglutide across a range of outcomes and to test whether these effects were consistent across key patient subgroups., Methods: We conducted a prespecified pooled analysis of individual patient data from STEP-HFpEF and STEP-HFpEF DM, randomised, double-blind, placebo-controlled trials at 129 clinical research sites in 18 countries. In both trials, eligible participants were aged 18 years or older, had heart failure with a left ventricular ejection fraction of at least 45%, a BMI of at least 30 kg/m 2 , New York Heart Association class II-IV symptoms, and a Kansas City Cardiomyopathy Questionnaire Clinical Summary Score (KCCQ-CSS; a measure of heart failure-related symptoms and physical limitations) of less than 90 points. In STEP-HFpEF, people with diabetes or glycated haemoglobin A 1c concentrations of at least 6·5% were excluded, whereas for inclusion in STEP-HFpEF DM participants had to have been diagnosed with type 2 diabetes at least 90 days before screening and to have an HbA 1c of 10% or lower. In both trials, participants were randomly assigned to either 2·4 mg semaglutide once weekly or matched placebo for 52 weeks. The dual primary endpoints were change from baseline to week 52 in KCCQ-CSS and bodyweight in all randomly assigned participants. Confirmatory secondary endpoints included change from baseline to week 52 in 6-min walk distance, a hierarchical composite endpoint (all-cause death, heart failure events, and differences in changes in KCCQ-CSS and 6-min walk distance); and C-reactive protein (CRP) concentrations. Heterogeneity in treatment effects was assessed across subgroups of interest. We assessed safety in all participants who received at least one dose of study drug., Findings: Between March 19, 2021 and March 9, 2022, 529 people were randomly assigned in STEP-HFpEF, and between June 27, 2021 and Sept 2, 2022, 616 were randomly assigned in STEP-HFpEF DM. Overall, 1145 were included in our pooled analysis, 573 in the semaglutide group and 572 in the placebo group. Improvements in KCCQ-CSS and reductions in bodyweight between baseline and week 52 were significantly greater in the semaglutide group than in the placebo group (mean between-group difference for the change from baseline to week 52 in KCCQ-CSS 7·5 points [95% CI 5·3 to 9·8]; p<0·0001; mean between-group difference in bodyweight at week 52 -8·4% [-9·2 to -7·5]; p<0·0001). For the confirmatory secondary endpoints, 6-min walk distance (mean between-group difference at week 52 17·1 metres [9·2 to 25·0]) and the hierarchical composite endpoint (win ratio 1·65 [1·42 to 1·91]) were significantly improved, and CRP concentrations (treatment ratio 0·64 [0·56 to 0·72]) were significantly reduced, in the semaglutide group compared with the placebo group (p<0·0001 for all comparisons). For the dual primary endpoints, the efficacy of semaglutide was largely consistent across multiple subgroups, including those defined by age, race, sex, BMI, systolic blood pressure, baseline CRP, and left ventricular ejection fraction. 161 serious adverse events were reported in the semaglutide group compared with 301 in the placebo group., Interpretation: In this prespecified pooled analysis of the STEP-HFpEF and STEP-HFpEF DM trials, semaglutide was superior to placebo in improving heart failure-related symptoms and physical limitations, and reducing bodyweight in participants with obesity-related heart failure with preserved ejection fraction. These effects were largely consistent across patient demographic and clinical characteristics.

Background: Obesity and type 2 diabetes are prevalent in patients with heart failure with preserved ejection fraction and are characterized by a high symptom burden. No approved therapies specifically target obesity-related heart failure with preserved ejection fraction in persons with type 2 diabetes., Methods: We randomly assigned patients who had heart failure with preserved ejection fraction, a body-mass index (the weight in kilograms divided by the square of the height in meters) of 30 or more, and type 2 diabetes to receive once-weekly semaglutide (2.4 mg) or placebo for 52 weeks. The primary end points were the change from baseline in the Kansas City Cardiomyopathy Questionnaire clinical summary score (KCCQ-CSS; scores range from 0 to 100, with higher scores indicating fewer symptoms and physical limitations) and the change in body weight. Confirmatory secondary end points included the change in 6-minute walk distance; a hierarchical composite end point that included death, heart failure events, and differences in the change in the KCCQ-CSS and 6-minute walk distance; and the change in the C-reactive protein (CRP) level., Results: A total of 616 participants underwent randomization. The mean change in the KCCQ-CSS was 13.7 points with semaglutide and 6.4 points with placebo (estimated difference, 7.3 points; 95% confidence interval [CI], 4.1 to 10.4; P<0.001), and the mean percentage change in body weight was -9.8% with semaglutide and -3.4% with placebo (estimated difference, -6.4 percentage points; 95% CI, -7.6 to -5.2; P<0.001). The results for the confirmatory secondary end points favored semaglutide over placebo (estimated between-group difference in change in 6-minute walk distance, 14.3 m [95% CI, 3.7 to 24.9; P = 0.008]; win ratio for hierarchical composite end point, 1.58 [95% CI, 1.29 to 1.94; P<0.001]; and estimated treatment ratio for change in CRP level, 0.67 [95% CI, 0.55 to 0.80; P<0.001]). Serious adverse events were reported in 55 participants (17.7%) in the semaglutide group and 88 (28.8%) in the placebo group., Conclusions: Among patients with obesity-related heart failure with preserved ejection fraction and type 2 diabetes, semaglutide led to larger reductions in heart failure-related symptoms and physical limitations and greater weight loss than placebo at 1 year.

Background: Phosphodiesterases degrade cyclic GMP (cGMP), the second messenger that mediates the cardioprotective effects of natriuretic peptides. High natriuretic peptide/cGMP ratio may reflect, in part, phosphodiesterase activity. Correlates of natriuretic peptide/cGMP in patients with heart failure with preserved ejection fraction are not well understood. Among patients with heart failure with preserved ejection fraction in the RELAX (Phosphodiesterase-5 Inhibition to Improve Clinical Status and Exercise Capacity in Heart Failure With Preserved Ejection Fraction) trial, we examined (1) cross-sectional correlates of circulating NT-proBNP (N-terminal pro-B-type natriuretic peptide)/cGMP ratio, (2) whether selective phosphodiesterase-5 inhibition by sildenafil changed the ratio, and (3) whether the effect of sildenafil on 24-week outcomes varied by baseline ratio., Methods and Results: In 212 subjects, NT-proBNP/cGMP ratio was calculated at randomization and 24 weeks. Correlates of the ratio and its change were examined in multivariable proportional odds models. Whether baseline ratio modified the sildenafil effect on outcomes was examined by interaction terms. Higher NT-proBNP/cGMP ratio was associated with greater left ventricular mass and troponin, the presence of atrial fibrillation, and lower estimated glomerular filtration rate and peak oxygen consumption. Compared with placebo, sildenafil did not alter the ratio from baseline to 24 weeks ( P =0.17). The effect of sildenafil on 24-week change in peak oxygen consumption, left ventricular mass, or clinical composite outcome was not modified by baseline NT-proBNP/cGMP ratio ( P -interaction >0.30 for all)., Conclusions: Among patients with heart failure with preserved ejection fraction, higher NT-proBNP/cGMP ratio associated with an adverse cardiorenal phenotype, which was not improved by selective phosphodiesterase-5 inhibition. Other phosphodiesterases may be greater contributors than phosphodiesterase-5 to the adverse phenotype associated with a high natriuretic peptide/cGMP ratio in HFpEF., Registration Information: clinicaltrials.gov. Identifier: NCT00763867.

Aims: Patients with heart failure (HF) and history of myocardial infarction (MI) face a higher risk of disease progression and clinical events. Whether sodium-glucose cotransporter 2 inhibitors may modify clinical trajectory in such individuals remains incompletely understood., Methods and Results: The DAPA-HF and DELIVER trials compared dapagliflozin with placebo in patients with symptomatic HF with left ventricular ejection fraction (LVEF) ≤40% and > 40%, respectively. In this pooled participant-level analysis, we assessed efficacy and safety outcomes by history of MI. The primary outcome in both trials was the composite of cardiovascular death or worsening HF. Of the total of 11 007 patients, 3731 (34%) had a previous MI and were at higher risk of the primary outcome across the spectrum of LVEF in covariate-adjusted models (hazard ratio [HR] 1.12, 95% confidence interval [CI] 1.02-1.24). Dapagliflozin reduced the risk of the primary outcome to a similar extent in patients with (HR 0.83, 95% CI 0.72-0.96) and without previous MI (HR 0.76, 95% CI 0.68-0.85; p interaction  = 0.36), with consistent benefits on key secondary outcomes as well. Serious adverse events did not occur more frequently with dapagliflozin, irrespective of previous MI., Conclusion: History of MI confers increased risks of adverse cardiovascular outcomes in patients with HF across the LVEF spectrum, even among those with preserved ejection fraction. Dapagliflozin consistently and safely reduces the risk of cardiovascular death or worsening HF, regardless of previous MI., (© 2024 The Authors.

Aims: Left ventricular (LV) subclinical impairment has been described in heart failure with preserved ejection fraction (HFpEF). We assessed the relationship between LV myocardial deformation by strain imaging and recurrent hospitalization for heart failure (HF) or cardiovascular death in a large international HFpEF population., Methods and Results: We assessed two-dimensional speckle-tracking based global longitudinal strain (GLS) in 790 patients (mean age 74 ± 8 years, 54% female) with adequate image quality enrolled in the PARAGON-HF echocardiography study. We examined the relationship of GLS with total HF hospitalizations and cardiovascular death (the primary composite outcome) after accounting for clinical confounders. Approximately 47% of the population had evidence of LV subclinical dysfunction, defined as absolute GLS <16%. Impaired GLS was significantly associated with higher values of circulating baseline N-terminal pro-B-type-natriuretic peptide. After a median follow-up of 3.0 years, there were 407 total HF hospitalizations and cardiovascular deaths. After multivariable adjustment, worse GLS was associated with a greater risk for the primary composite outcome (adjusted hazard ratio per 1% decrease: 1.06; 95% confidence interval 1.02-1.11; p = 0.008). GLS did not modify the treatment effect of sacubitril/valsartan compared with valsartan for the composite outcome (p for interaction >0.1)., Conclusions: In a large HFpEF population, impaired LV function was observed even among patients with preserved ejection fraction, and was associated with an increased risk of total HF hospitalizations or cardiovascular death, accounting for clinical confounders. These findings highlight the key role of subtle LV systolic impairment in the pathophysiology of HFpEF., (© 2024 European Society of Cardiology.)

Background: Although beta-blockers are not recommended for the treatment of heart failure with preserved ejection fraction (HFpEF) according to the latest European Society of Cardiology and American Heart Association/American College of Cardiology/Heart Failure Society of America guidelines, these therapies remain commonly used for comorbidity management. There has been concern that beta-blockers may adversely influence clinical outcomes by limiting chronotropic response in HFpEF., Objectives: This study sought to examine the contemporary use and implications of beta-blockers in patients with heart failure with mildly reduced ejection fraction (HFmrEF) or HFpEF., Methods: In the DELIVER (Dapagliflozin Evaluation to Improve the Lives of Patients With Preserved Ejection Fraction Heart Failure) trial, a total of 6,263 patients with symptomatic heart failure (HF) with a left ventricular ejection fraction (LVEF) >40% were randomized to dapagliflozin or placebo across 20 countries. In this prespecified analysis, efficacy and safety outcomes were examined according to beta-blocker use at randomization. The primary outcome was cardiovascular death or worsening HF., Results: Overall, beta-blockers were used in 5,177 patients (83%), with wide variation by geographic region. Beta-blocker use was associated with a lower risk of the primary outcome in covariate-adjusted models (HR: 0.70; 95% CI: 0.60-0.83). Dapagliflozin consistently reduced the risk of the primary outcome in patients taking beta-blockers (HR: 0.82; 95% CI: 0.72-0.94) and in patients not taking beta-blockers (HR: 0.79; 95% CI: 0.61-1.03; P interaction  = 0.85), with similar findings for key secondary endpoints. Adverse events were balanced between patients randomized to dapagliflozin and placebo, regardless of background beta-blocker use., Conclusions: In patients with HFmrEF or HFpEF who were enrolled in DELIVER, 4 out of 5 participants were treated with a beta-blocker. Beta-blocker use was not associated with a higher risk of worsening HF or cardiovascular death. Dapagliflozin consistently and safely reduced clinical events, irrespective of background beta-blocker use.

Background: Although VCAM-1 (vascular cell adhesion molecule-1) and ICAM-1 (intercellular adhesion molecule-1) have been associated with incident heart failure with preserved ejection fraction (HFpEF) and atrial fibrillation (AF), the associations of VCAM-1 and ICAM-1 with sensitive measures of cardiac structure/function are unclear. The objective of this study is to evaluate associations between VCAM-1, ICAM-1, and measures of cardiac structure and function as potential pathways through which cellular adhesion molecules promote HFpEF and AF risk., Methods and Results: In MESA (Multi-Ethnic Study of Atherosclerosis), we evaluated the associations of circulating VCAM-1 and ICAM-1 at examination 2 (2002-2004) with measures of cardiac structure/function on cardiac magnetic resonance imaging at examination 5 (2010-2011) after multivariable adjustment. Mediation analysis of left atrial (LA) strain on the association between VCAM-1 or ICAM-1 and AF or HFpEF was also performed. Overall, 2304 individuals (63±10 years; 47% men) with VCAM-1 or ICAM-1, cardiac magnetic resonance imaging, and covariate data were included in analysis. Higher VCAM-1 and ICAM-1 were associated with lower LA peak longitudinal strain and worse global circumferential left ventricular strain but were not associated with left ventricular myocardial scar or interstitial fibrosis. Lower LA peak longitudinal strain mediated 8% (95% CI, 2-30) of the relationship between VCAM-1 and HFpEF and 9% (95% CI, 2-21) of the relationship between VCAM-1 and AF., Conclusions: Higher VCAM-1 and ICAM-1 were associated with lower LA function and left ventricular systolic function but were not associated with myocardial scar or interstitial fibrosis. VCAM-1 and ICAM-1 may promote HFpEF and AF risk through impaired LA reservoir function.

Background: Sodium-glucose cotransporter 2 inhibitors reduce the risk of worsening heart failure (HF) and cardiovascular death in patients with HF irrespective of left ventricular ejection fraction. It is important to determine whether therapies for HF improve symptoms and functional capacity., Methods: The DETERMINE (Dapagliflozin Effect on Exercise Capacity Using a 6-Minute Walk Test in Patients With Heart Failure) double-blind, placebo-controlled, multicenter trials assessed the efficacy of the sodium-glucose cotransporter 2 inhibitor dapagliflozin on the Total Symptom Score (TSS) and Physical Limitation Scale (PLS) of the Kansas City Cardiomyopathy Questionnaire (KCCQ) and 6-minute walk distance (6MWD) in 313 patients with HF with reduced ejection fraction (DETERMINE-Reduced) and in 504 patients with HF with preserved ejection fraction (DETERMINE-Preserved) with New York Heart Association class II or III symptoms and elevated natriuretic peptide levels. The primary outcomes were changes in the KCCQ-TSS, KCCQ-PLS, and 6MWD after 16 weeks of treatment., Results: Among the 313 randomized patients with HF with reduced ejection fraction, the median placebo-corrected difference in KCCQ-TSS from baseline at 16 weeks was 4.2 (95% CI, 1.0, 8.2; P =0.022) in favor of dapagliflozin. The median placebo-corrected difference in KCCQ-PLS was 4.2 (95% CI, 0.0, 8.3; P =0.058). The median placebo-corrected difference in 6MWD from baseline at 16 weeks was 3.2 meters (95% CI, -6.5, 13.0; P =0.69). In the 504 patients with HF with preserved ejection fraction, the median placebo-corrected 16-week difference in KCCQ-TSS and KCCQ-PLS was 3.2 (95% CI, 0.4, 6.0; P =0.079) and 3.1 (-0.1, 5.4; P =0.23), respectively. The median 16-week difference in 6MWD was 1.6 meters (95% CI, -5.9, 9.0; P =0.67). In an exploratory post hoc analysis of both trials combined (DETERMINE-Pooled), the median placebo-corrected difference from baseline at 16 weeks was 3.7 (1.5, 5.9; P =0.005) for KCCQ-TSS, 4.0 (0.3, 4.9; P =0.036) for KCCQ-PLS, and 2.5 meters (-3.5, 8.4; P =0.50) for 6MWD., Conclusions: Dapagliflozin improved the KCCQ-TSS in patients with HF with reduced ejection fraction but did not improve KCCQ-PLS or 6MWD. Dapagliflozin did not improve these outcomes in patients with HF with preserved ejection fraction. In a post hoc analysis including all patients across the full spectrum of ejection fraction, there was a beneficial effect of dapagliflozin on KCCQ-TSS and KCCQ-PLS but not 6MWD., Registration: URL: https://www.clinicaltrials.gov; Unique identifiers: NCT03877237 and NCT03877224., Competing Interests: Disclosures Dr McMurray has received payments through Glasgow University for work on clinical trials; consulting fees and other activities from Alnylam, Amgen, AstraZeneca, Bayer, Boehringer Ingelheim, Bristol Myers Squibb, Cardurion, Cytokinetics, Dal-Cor, GlaxoSmithKline, Ionis, KBP Biosciences, Novartis, Pfizer, and Theracos; personal lecture fees from Corpus, Abbott, Hikma, Sun Pharmaceuticals, Medscape/Heart.Org, Radcliffe Cardiology, and Servier; and has served as director of Global Clinical Trial Partners.

Background: The sodium glucose cotransporter-2 inhibitors are guideline-recommended to treat heart failure across the spectrum of left ventricular ejection fraction; however, economic evaluations of adding sodium glucose cotransporter-2 inhibitors to standard of care in chronic heart failure across a broad left ventricular ejection fraction range are lacking., Methods and Results: We conducted a US-based cost-effectiveness analysis of dapagliflozin added to standard of care in a chronic heart failure population using pooled, participant data from the DAPA-HF (Dapagliflozin and Prevention of Adverse Outcomes in Heart Failure) and DELIVER (Dapagliflozin Evaluation to Improve the Lives of Patients With Preserved Ejection Fraction Heart Failure) trials. The 3-state Markov model used estimates of transitional probabilities, effectiveness of dapagliflozin, and utilities from the pooled trials. Costs estimates were obtained from published sources, including published rebates in dapagliflozin cost. Adding dapagliflozin to standard of care was estimated to produce an additional 0.53 quality-adjusted life years (QALYs) compared with standard of care alone. Incremental cost effectiveness ratios were $85 554/QALY when using the publicly reported full (undiscounted) Medicare cost ($515/month) and $40 081/QALY, at a published nearly 50% rebate ($263/month). The addition of dapagliflozin to standard of care would be of at least intermediate value (<$150 000/QALY) at a cost of <$872.58/month, of high value (<$50 000/QALY) at <$317.66/month, and cost saving at <$40.25/month. Dapagliflozin was of at least intermediate value in 92% of simulations when using the full (undiscounted) Medicare list cost in probabilistic sensitivity analyses. Cost effectiveness was most sensitive to the dapagliflozin cost and the effect on cardiovascular death., Conclusions: The addition of dapagliflozin to standard of care in patients with heart failure across the spectrum of ejection fraction was at least of intermediate value at the undiscounted Medicare cost and may be potentially of higher value on the basis of the level of discount, rebates, and price negotiations offered., Registration: URL: https://www.clinicaltrials.gov; Unique identifiers: NCT01035255 & NCT01920711.

Background: Current prevalence estimates of heart failure (HF) are primarily based on self-report or HF hospitalizations. There is an unmet need to define the prevalence and pathogenesis of early symptomatic HF, which may be undiagnosed and precedes HF hospitalization., Methods: The MESA (Multi-Ethnic Study of Atherosclerosis) Early HF study was conducted during MESA exam 6 to determine the prevalence of early HF and investigate the transition from risk factors to early HF in a diverse population-based cohort of older adults. Between 2016 and 2018, 3285 MESA participants from 6 field centers underwent comprehensive speckle-tracking echocardiography with passive leg raise maneuver, Kansas City Cardiomyopathy Questionnaire, 6-minute walk test, arterial stiffness assessment, and proteomics (including NT-proBNP [N-terminal pro-B-type natriuretic peptide])., Results: Median age was 73 (25th-75th percentile 67-81) years, 53.2% were female, 25.6% were Black, 12.8% were Chinese, and 40.0% were White. The prevalence of HF risk factors was high: hypertension, 61.9%; former or current smoking, 53.7%; obesity 34.8%; diabetes; 24.7%; and chronic kidney disease; 22%. Overt cardiovascular disease, which ranged from 2.1% (HF) to 13.6% (atrial fibrillation), was less common. Of the 3285 participants, 96% underwent proteomics, 94% Kansas City Cardiomyopathy Questionnaire, 93% speckle-tracking echocardiography with passive leg raise, 82% arterial stiffness exam, and 77% 6-minute walk test. Feasibility of resting speckle-tracking echocardiography (87%-99% across cardiac chambers) and passive leg raise Doppler/speckle-tracking echocardiography (>84%) measurements was high. A total of 120 unique echocardiographic indices were measured., Conclusions: The MESA Early HF study is a key resource for cardiovascular researchers who are interested in improving the epidemiological and phenotypic characterization of early HF., Registration: URL: https://www.clinicaltrials.gov; Unique identifier: NCT00005487., Competing Interests: Dr Shah has received research grants from AstraZeneca, Corvia Medical, and Pfizer and has received consulting fees from and consulting fees from Abbott, AstraZeneca, Alleviant, Amgen, Aria CV, Axon Therapies, Bayer, Boehringer Ingelheim, Boston Scientific, Bristol Myers Squibb, Cyclerion, Cytokinetics, Edwards Lifesciences, Eidos, Imara, Impulse Dynamics, Intellia, Ionis, Lilly, Merck, Metabolic Flux, MyoKardia, NGM Biopharmaceuticals, Novartis, Novo Nordisk, Pfizer, Prothena, Regeneron, Rivus, Sardocor, Shifamed, Tenax, Tenaya, Ultromics, and United Therapeutics.

Importance: Heart failure with improved ejection fraction (HFimpEF), defined as prior left ventricular ejection fraction (LVEF) 40% or lower that has increased to greater than 40%, is understudied., Objective: To examine mode of death and the association of dapagliflozin with reductions in cause-specific death in patients with HFimpEF., Design, Setting, and Participants: This was a post hoc analysis from the Dapagliflozin Evaluation to Improve the Lives of Patients With Preserved Ejection Fraction Heart Failure (DELIVER) randomized clinical trial, conducted from August 2018 to December 2020. The trial randomly assigned patients with HF with LVEF greater than 40%, New York Heart Association class II to IV symptoms, and elevated natriuretic peptides to treatment with dapagliflozin (10 mg, once daily) or placebo. The presence of HFimpEF was captured through study case report forms. The primary outcome was a composite of worsening HF events (hospitalization or urgent HF visits) or cardiovascular death. Clinical outcomes were adjudicated by a blinded clinical end points committee. Data were analyzed from May 2022 to August 2023., Intervention: Dapagliflozin vs placebo., Main Outcomes and Measures: The mode of death in relation to HFimpEF status was examined, as well as the association of randomized treatment with cause-specific death in Cox regression models., Results: Of 1151 patients with HFimpEF in DELIVER, 190 (16.5%) died, compared with 833 patients (16.3%) of 5112 with LVEF consistently greater than 40%. The overall distribution of mode of death was similar in those with HFimpEF compared with those with LVEF consistently greater than 40% (noncardiovascular death: 103 of 190 [54%] vs 428 of 833 [51%]; cardiovascular death: 87 of 190 [46%] vs 405 of 833 [49%], respectively). Most deaths in individuals with HFimpEF were noncardiovascular (103 of 180 [54%]). For cardiovascular deaths, sudden deaths were most common (36 of 190 events [19%]), followed by HF-related (29 of 190 events [15%]). Among patients with HFimpEF, treatment with dapagliflozin was associated with lower rates of cardiovascular death relative to placebo, a difference primarily due to lower rates of sudden death (hazard ratio, 0.38; 95% CI, 0.18-0.79; P for interaction = .01)., Conclusions and Relevance: The findings in this study support current guideline recommendations for use of sodium-glucose transport protein 2 inhibitor therapy, and further suggest that the addition of a sodium-glucose transport protein 2 inhibitor therapy to other guideline-directed medical therapies may help reduce cardiovascular mortality in patients with HFimpEF., Trial Registration: ClinicalTrials.gov Identifier: NCT03619213.

Background: Atrial fibrillation (AF) is common in patients with heart failure with preserved ejection fraction (HFpEF) and is associated with poorer clinical outcomes. The prevalence of subclinical AF in patients with HFpEF remains unknown., Objectives: The aim of this study was to determine whether subclinical AF was more prevalent in individuals with HFpEF than in individuals without histories of heart failure (HF)., Methods: Patients with HFpEF with no prior diagnoses of AF were screened for subclinical AF, and the prevalence of subclinical AF was compared with that among control subjects without HF drawn from MESA (Multi-Ethnic Study of Atherosclerosis) who underwent the same electrocardiographic monitoring. Multivariable logistic regression was used to adjust for demographic and clinical comorbidities., Results: Ninety patients with HFpEF and 1,230 MESA participants were included. Patients with HFpEF were younger (median age 69 years [Q1-Q3: 63-76 years] vs 72 years [Q1-Q3: 66-80 years]; P = 0.02), more obese (median body mass index 36 kg/m 2 [Q1-Q3: 30-45 kg/m 2 ] vs 27 kg/m 2 [Q1-Q3: 24-30 kg/m 2 ]; P < 0.001), and more likely to have diabetes (34% vs 21%; P = 0.01). The prevalence of subclinical AF was 8.9% in patients with HFpEF and 4.1% in non-HF participants. After multivariable adjustment for age, sex, race, body mass index, diabetes, smoking, and total analyzable time on electrocardiographic monitor, there was a significantly higher odds of subclinical AF in patients with HFpEF compared with MESA (OR: 3.01; 95% CI: 1.13-7.99; P = 0.03)., Conclusions: Patients with HFpEF had a higher prevalence of subclinical AF than participants without HF from a community-based study. Screening for atrial arrhythmias may be appropriate among patients with HFpEF for timely initiation of thromboembolic prophylaxis and may identify individuals at greater risk for clinical decompensation., Competing Interests: Funding Support and Author Disclosures This research was supported by contracts 75N92020D00001, HHSN268201500003I, N01-HC-95159, 75N92020D00005, N01-HC-95160, 75N92020D00002, N01-HC-95161, 75N92020D00003, N01-HC-95162, 75N92020D00006, N01-HC-95163, 75N92020D00004, N01-HC-95164, 75N92020D00007, N01-HC-95165, N01-HC-95166, N01-HC-95167, N01-HC-95168, and N01-HC-95169 and grants R01HL127659 and R01HL127028 from the National Heart, Lung, and Blood Institute and by grants UL1-TR-000040, UL1-TR-001079, and UL1-TR-001420 from the National Center for Advancing Translational Sciences.

Background: Sleep apnea is more common in patients with heart failure (HF) than in the general population, but little is known about its association with clinical outcomes in various HF phenotypes or how it might modify the effect of HF therapy., Objectives: To examine the prevalence of sleep apnea, its association with outcomes and the effects of dapagliflozin in patients with HF with and without sleep apnea in a pooled analysis of 2 trials comparing dapagliflozin to placebo in HFrEF (DAPA-HF trial) and HFmrEF/HFpEF (DELIVER trial)., Methods: A history of sleep apnea was investigator-reported. The primary outcome was a composite of worsening HF or cardiovascular death., Results: The prevalence of sleep apnea was 5.7% and 7.8% in patients with HFrEF and HFmrEF/HFpEF, respectively. The primary outcome occurred at a rate of 16.0 in participants with sleep apnea compared to 10.6 per 100 person-years in those without (adjusted HR 1.29 [95%CI, 1.10-1.52]). Compared with placebo, dapagliflozin reduced the risk of the primary endpoint to the same extent in patients with (HR 0.78 [95% CI, 0.59-1.03]) and without sleep apnea (HR 0.79 [0.72-0.87]) [P interaction  = 0.93]. The beneficial effects of dapagliflozin on other clinical outcomes and symptom burden, physical function, and quality of life were consistent in participants with and without sleep apnea., Conclusions: In DAPA-HF and DELIVER, the true prevalence of sleep apnea was likely underestimated. An investigator-reported history of sleep apnea was associated with higher rates of worsening HF events. The benefits of dapagliflozin on clinical outcomes were consistent in patients with and without sleep apnea., Clinical Trial Registration: Unique identifiers: NCT01920711 CONDENSED ABSTRACT: In a pooled analysis of the DAPA-HF and DELIVER trials of more than 11,000 patients with heart failure (HF) across the range of ejection fractions, an investigator-reported history of sleep apnea was associated with higher rates of worsening HF events but not mortality. The beneficial effects of dapagliflozin on clinical outcomes were consistent in patients with and without sleep apnea. These findings provide further evidence for dapagliflozin as a new treatment option for patients with heart failure across the range of ejection fractions., Competing Interests: Disclosures JHB reports advisory board honoraria from AstraZeneca and Bayer, consultant honoraria from Novartis and AstraZeneca and travel grants from AstraZeneca.

Background: The renal sympathetic nervous system modulates systemic blood pressure, cardiac performance, and renal function. Pathological increases in renal sympathetic nerve activity contribute to the pathogenesis of heart failure with preserved ejection fraction (HFpEF). We investigated the effects of renal sympathetic denervation performed at early or late stages of HFpEF progression., Methods and Results: Male ZSF1 obese rats were subjected to radiofrequency renal denervation (RF-RDN) or sham procedure at either 8 weeks or 20 weeks of age and assessed for cardiovascular function, exercise capacity, and cardiorenal fibrosis. Renal norepinephrine and renal nerve tyrosine hydroxylase staining were performed to quantify denervation following RF-RDN. In addition, renal injury, oxidative stress, inflammation, and profibrotic biomarkers were evaluated to determine pathways associated with RDN. RF-RDN significantly reduced renal norepinephrine and tyrosine hydroxylase content in both study cohorts. RF-RDN therapy performed at 8 weeks of age attenuated cardiac dysfunction, reduced cardiorenal fibrosis, and improved endothelial-dependent vascular reactivity. These improvements were associated with reductions in renal injury markers, expression of renal NLR family pyrin domain containing 3/interleukin 1β, and expression of profibrotic mediators. RF-RDN failed to exert beneficial effects when administered in the 20-week-old HFpEF cohort., Conclusions: Our data demonstrate that early RF-RDN therapy protects against HFpEF disease progression in part due to the attenuation of renal fibrosis and inflammation. In contrast, the renoprotective and left ventricular functional improvements were lost when RF-RDN was performed in later HFpEF progression. These results suggest that RDN may be a viable treatment option for HFpEF during the early stages of this systemic inflammatory disease.

Importance: An initial decline in estimated glomerular filtration rate (eGFR) is expected after initiating a sodium-glucose cotransporter-2 inhibitor (SGLT2i) and has been observed across patients with diabetes, chronic kidney disease, and heart failure., Objective: To examine the implications of initial changes in eGFR among patients with heart failure with mildly reduced ejection fraction (HFmrEF) or preserved ejection fraction (HFpEF) enrolled in the Dapagliflozin Evaluation to Improve the Lives of Patients With Preserved Ejection Fraction Heart Failure (DELIVER) trial., Design, Setting, and Participants: This was a prespecified analysis of the results of the DELIVER randomized clinical trial, which was an international multicenter study of patients with EF greater than 40% and eGFR greater than or equal to 25. The DELIVER trial took place from August 2018 to March 2022. Data for the current prespecified study were analyzed from February to October 2023., Intervention: Dapagliflozin, 10 mg per day, or placebo., Main Outcomes and Measures: In this prespecified analysis, the frequency of an initial eGFR decline (baseline to month 1) was compared between dapagliflozin and placebo. Cox models adjusted for baseline eGFR and established prognostic factors were fit to estimate the association of an initial eGFR decline with cardiovascular (cardiovascular death or heart failure event) and kidney (≥50% eGFR decline, eGFR<15 or dialysis, death from kidney causes) outcomes, landmarked at month 1, stratified by diabetes., Results: Study data from 5788 participants (mean [SD] age, 72 [10] years; 3253 male [56%]) were analyzed. The median (IQR) change in eGFR level from baseline to month 1 was -1 (-6 to 5) with placebo and -4 (-9 to 1) with dapagliflozin (difference, -3; P < .001). A higher proportion of patients assigned to dapagliflozin developed an initial eGFR decline greater than 10% vs placebo (1144 of 2892 [40%] vs 737 of 2896 [25%]; odds ratio, 1.9; 95% CI, 1.7-2.1; P difference <.001). An initial eGFR decline of greater than 10% (vs ≤10%) was associated with a higher risk of the primary cardiovascular outcome among those randomized to placebo (adjusted hazard ratio [aHR], 1.33; 95% CI, 1.10-1.62) but not among those randomized to dapagliflozin (aHR, 0.90; 95% CI, 0.74-1.09; P for interaction = .01). Similar associations were observed when alternative thresholds of initial eGFR decline were considered and when analyzed as a continuous measure. An initial eGFR decline of greater than 10% was not associated with adverse subsequent kidney composite outcomes in dapagliflozin-treated patients (aHR, 0.94; 95% CI, 0.49-1.82)., Conclusions and Relevance: Among patients with HFmrEF or HFpEF treated with dapagliflozin, an initial eGFR decline was frequent but not associated with subsequent risk of cardiovascular or kidney events. These data reinforce clinical guidance that SGLT2is should not be interrupted or discontinued in response to an initial eGFR decline., Trial Registration: ClinicalTrials.gov Identifier: NCT03619213.
