Objectives: We describe the development of 3D-printed stents using our digital workflow and their effects on patients enrolled in the lead-in phase of a multi-center, randomized Phase-II trial., Materials and Methods: Digital dental models were created for patients using intraoral scanning. Digital processes were implemented to develop the mouth-opening, tongue-depressing, and tongue-lateralizing stents using stereolithography. Time spent and material 3D-printing costs were measured. Physicians assessed mucositis using the Oral Mucositis Assessment Scale (OMAS) and collected MD Anderson Symptom Inventory (MDASI) reports and adverse events (AEs) from patients at various time points (TPs). OMAS and MDASI results were evaluated using paired t-test analysis., Results: 18 patients enrolled into the lead-in phase across 6 independent clinical sites in the USA. 15 patients received stents (average design and fabrication time, 8 h; average material 3D-printing cost, 11 USD). 10 eligible patients with complete OMAS and MDASI reports across all TPs were assessed. OMAS increased significantly from baseline to week 3 of treatment (mean difference = 0.34; 95 % CI, 0.09-0.60; p = 0.01). MDASI increased significantly from baseline to week 3 of treatment (mean difference = 1.02; 95 % CI, 0.40-1.70; p = 0.005), and week 3 of treatment to end of treatment (mean difference = 1.90; 95 % CI, 0.90-2.92; p = 0.002). AEs (grades 1-3) were reported by patients across TPs. Mucositis and radiation dermatitis were primarily attributed to chemoradiation., Conclusions: 3D-printed stents were successfully fabricated and well tolerated by patients. As patients enroll in the randomized phase of this trial, data herein will establish a baseline for comparative analysis., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Published by Elsevier Ltd.)

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.

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.

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).

Background: Considering the high prevalence of mitral regurgitation (MR) and the highly subjective, variable MR severity reporting, an automated tool that could screen patients for clinically significant MR (≥ moderate) would streamline the diagnostic/therapeutic pathways and ultimately improve patient outcomes., Objectives: The authors aimed to develop and validate a fully automated machine learning (ML)-based echocardiography workflow for grading MR severity., Methods: ML algorithms were trained on echocardiograms from 2 observational cohorts and validated in patients from 2 additional independent studies. Multiparametric echocardiography core laboratory MR assessment served as ground truth. The machine was trained to measure 16 MR-related parameters. Multiple ML models were developed to find the optimal parameters and preferred ML model for MR severity grading., Results: The preferred ML model used 9 parameters. Image analysis was feasible in 99.3% of cases and took 80 ± 5 seconds per case. The accuracy for grading MR severity (none to severe) was 0.80, and for significant (moderate or severe) vs nonsignificant MR was 0.97 with a sensitivity of 0.96 and specificity of 0.98. The model performed similarly in cases of eccentric and central MR. Patients graded as having severe MR had higher 1-year mortality (adjusted HR: 5.20 [95% CI: 1.24-21.9]; P = 0.025 compared with mild)., Conclusions: An automated multiparametric ML model for grading MR severity is feasible, fast, highly accurate, and predicts 1-year mortality. Its implementation in clinical practice could improve patient care by facilitating referral to specialized clinics and access to evidence-based therapies while improving quality and efficiency in the echocardiography laboratory., Competing Interests: Funding Support and Author Disclosures Mr Jiang is an employee of Us2.ai.

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: 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: 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: Obesity and insulin resistance are prevalent in heart failure with preserved ejection fraction (HFpEF) and are associated with adverse cardiovascular outcomes. Measuring insulin resistance is difficult outside of research settings, and its correlation to parameters of myocardial dysfunction and functional status is unknown., Methods: A total of 92 HFpEF patients with New York Heart Association class II to IV symptoms underwent clinical assessment, 2D echocardiography, and 6-min walk (6 MW) test. Insulin resistance was defined by estimated glucose disposal rate (eGDR) using the formula: eGDR = 19.02 - [0.22 × body mass index (BMI), kg/m 2 ] - (3.26 × hypertension, presence) - (0.61 × glycated hemoglobin, %). Lower eGDR indicates increased insulin resistance (unfavorable). Myocardial structure and function were assessed by left ventricular (LV) mass, average E/e' ratio, right ventricular systolic pressure, left atrial volume, LV ejection fraction, LV longitudinal strain (LVLS), and tricuspid annular plane systolic excursion. Associations between eGDR and adverse myocardial function were evaluated in unadjusted and multivariable-adjusted analyses using analysis of variance testing and multivariable linear regression., Results: Mean age (SD) was 65 (11) years, 64 % were women, and 95 % had hypertension. Mean (SD) BMI was 39 (9.6) kg/m 2 , glycated hemoglobin 6.7 (1.6) %, and eGDR 3.3 (2.6) mg × kg -1  min -1 . Increased insulin resistance was associated with worse LVLS in a graded fashion [mean (SD) -13.8 % (4.9 %), -14.4 % (5.8 %), -17.5 % (4.4 %) for first, second, and third eGDR tertiles, respectively, p = 0.047]. This association persisted after multivariable adjustment, p = 0.040. There was also a significant association between worse insulin resistance and decreased 6 MW distance on univariate analysis, but not on multivariable adjusted analysis., Conclusion: Our findings may inform treatment strategies focused on the use of tools to estimate insulin resistance and selection of insulin sensitizing drugs which may improve cardiac function and exercise capacity., Competing Interests: Disclosures SJS has received research grants from Actelion, AstraZeneca, Corvia, Novartis, and Pfizer; and has received consulting fees from Abbott, Actelion, AstraZeneca, Amgen, Aria CV, Axon Therapies, Bayer, Boehringer-Ingelheim, Boston Scientific, Bristol-Myers Squibb, Cardiora, Coridea, CVRx, Cyclerion, Cytokinetics, Edwards Lifesciences, Eidos, Eisai, Imara, Impulse Dynamics, Intellia, Ionis, Ironwood, Lilly, Merck, MyoKardia, Novartis, Novo Nordisk, Pfizer, Prothena, Regeneron, Rivus, Sanofi, Shifamed, Tenax, Tenaya, and United Therapeutics.

Introduction: The ICAM1 variant rs5491 ( p.K56M ) is common among Black individuals and has been associated with risk of heart failure with preserved ejection fraction (HFpEF). The pathways by which rs5491 leads to HFpEF are not known., Methods: Among Black individuals within the Multi-Ethnic Study of Atherosclerosis, we evaluated associations of rs5491 with 3 inflammatory biomarkers (high-sensitivity C-reactive protein [hsCRP], interleukin-6 [IL-6], and tumor necrosis factor-α receptor 1 [TNFR-1])., Results: Among 1558 Black participants (mean age 62 ± 10 y, 47 % female), each additional rs5491 allele was associated with higher hsCRP after covariate adjustment (β: 0.15, SE: 0.07, P = 0.02). Each additional rs5491 allele was associated with higher TNFR-1 (β: 0.06, SE: 0.02, P = 0.02), but not IL-6 (β: 0.04, SE: 0.04, P = 0.29). The association between rs5491 and HFpEF remained significant after adjustment for hsCRP., Conclusion: In Black individuals, rs5491 ( p.K56M ) is associated with higher hsCRP and higher TNFR-1, but not IL-6.

Background: Cardio-renal-metabolic (CRM) conditions are individually common among patients with heart failure (HF), but the prevalence and influence of overlapping CRM conditions in this population have not been well-studied., Objectives: This study aims to evaluate the impact of overlapping CRM conditions on clinical outcomes and treatment effects of dapagliflozin in HF., Methods: In this post hoc analysis of DELIVER (Dapagliflozin Evaluation to Improve the Lives of Patients With Preserved Ejection Fraction Heart Failure), we evaluated the prevalence of comorbid CRM conditions (atherosclerotic cardiovascular disease, chronic kidney disease, and type 2 diabetes), their impact on the primary outcome (cardiovascular death or worsening HF), and treatment effects of dapagliflozin by CRM status., Results: Among 6,263 participants, 1,952 (31%), 2,245 (36%), and 1,236 (20%) had 1, 2, and 3 additional CRM conditions, respectively. HF alone was uncommon (13%). Greater CRM multimorbidity was associated with older age, higher body mass index, longer-duration HF, worse health status, and lower left ventricular ejection fraction. Risk of the primary outcome increased with higher CRM overlap, with 3 CRM conditions independently associated with highest risk of primary events (adjusted HR: 2.16 [95% CI: 1.72-2.72]; P < 0.001) compared with HF alone. Relative benefits of dapagliflozin on the primary outcome were consistent irrespective of the type of CRM overlap (P interaction  = 0.773) and by the number of CRM conditions (P interaction  = 0.734), with greatest absolute benefits among those with highest CRM multimorbidity. Estimated 2-year numbers needed to treat with dapagliflozin to prevent 1 primary event were approximately 52, 39, 33, and 24 for participants with 0, 1, 2, and 3 additional CRM conditions at baseline, respectively. Adverse events between treatment arms were similar across the CRM spectrum., Conclusions: CRM multimorbidity was common and associated with adverse outcomes among patients with HF and left ventricular ejection fraction >40% in DELIVER. Dapagliflozin was safe and effective across the CRM spectrum, with greater absolute benefits among those with highest CRM overlap (Dapagliflozin Evaluation to Improve the LIVEs of Patients With Preserved Ejection Fraction Heart Failure [DELIVER]; NCT03619213)., Competing Interests: Funding Support and Author Disclosures DELIVER was sponsored by AstraZeneca.

Background: Patients with heart failure (HF) have a high burden of multimorbidity, often necessitating numerous medications. There may be clinical concern about introducing another medication, especially among individuals with polypharmacy., Objectives: This study examined the efficacy and safety of addition of dapagliflozin according to the number of concomitant medications in HF with mildly reduced or preserved ejection fraction., Methods: In this post hoc analysis of the DELIVER (Dapagliflozin Evaluation to Improve the Lives of Patients With Preserved Ejection Fraction Heart Failure) trial, 6,263 participants with symptomatic HF with left ventricular ejection fraction >40% were randomized to dapagliflozin or placebo. Baseline medication use (including vitamins and supplements) was collected. Efficacy and safety outcomes were assessed by medication use categories ("nonpolypharmacy": <5 medications; "polypharmacy": 5 to 9 medications; and "hyperpolypharmacy": ≥10 medications) and continuously. The primary outcome was worsening HF or cardiovascular death., Results: Overall, 3,795 (60.6%) patients met polypharmacy and 1,886 (30.1%) met hyperpolypharmacy criteria. Higher numbers of medications were strongly associated with higher comorbidity burden and increased rates of the primary outcome. Compared with placebo, dapagliflozin similarly reduced the risk of the primary outcome irrespective of polypharmacy status (nonpolypharmacy HR: 0.88 [95% CI: 0.58-1.34]; polypharmacy HR: 0.88 [95% CI: 0.75-1.03]; hyperpolypharmacy HR: 0.73 [95% CI: 0.60-0.88]; P interaction  = 0.30). Similarly, benefits with dapagliflozin were consistent across the spectrum of total medication use (P interaction  = 0.06). Although adverse events increased with higher number of medications, they were not more frequent with dapagliflozin, regardless of polypharmacy status., Conclusions: In the DELIVER trial, dapagliflozin safely reduced worsening HF or cardiovascular death across a broad range of baseline medication use, including among individuals with polypharmacy (Dapagliflozin Evaluation to Improve the Lives of Patients With Preserved Ejection Fraction Heart Failure [DELIVER]; NCT03619213)., Competing Interests: Funding support and author disclosures The DELIVER trial was funded by AstraZeneca.

Background: Atrial fibrillation (AF) is a common comorbidity in patients with heart failure with preserved ejection fraction (HFpEF) and in heart failure with mildly reduced ejection fraction (HFmrEF)., Objectives: This study sought to describe AF burden and its clinical impact among individuals with HFpEF and HFmrEF who participated in a randomized clinical trial of atrial shunt therapy (REDUCE LAP-HF II [A Study to Evaluate the Corvia Medical, Inc IASD System II to Reduce Elevated Left Atrial Pressure in Patients with Heart Failure]) and to evaluate the effect of atrial shunt therapy on AF burden., Methods: Study investigators characterized AF burden among patients in the REDUCE LAP-HF II trial by using ambulatory cardiac patch monitoring at baseline (median patch wear time, 6 days) and over a 12-month follow-up (median patch wear time, 125 days). The investigators determined the association of baseline AF burden with long-term clinical events and examined the effect of atrial shunt therapy on AF burden over time., Results: Among 367 patients with cardiac monitoring data at baseline and follow-up, 194 (53%) had a history of AF or atrial flutter (AFL), and median baseline AF burden was 0.012% (IQR: 0%-1.3%). After multivariable adjustment, baseline AF burden ≥0.012% was significantly associated with heart failure (HF) events (HR: 2.00; 95% CI: 1.17-3.44; P = 0.01) both with and without a history of AF or AFL (P for interaction = 0.68). Adjustment for left atrial reservoir strain attenuated the baseline AF burden-HF event association (HR: 1.71; 95% CI: 0.93-3.14; P = 0.08). Of the 367 patients, 141 (38%) had patch-detected AF during follow-up without a history of AF or AFL. Atrial shunt therapy did not change AF incidence or burden during follow-up., Conclusions: In HFpEF and HFmrEF, nearly 40% of patients have subclinical AF by 1 year. Baseline AF burden, even at low levels, is associated with HF events. Atrial shunt therapy does not affect AF incidence or burden.

Artificial intelligence (AI) promises to revolutionize many fields, but its clinical implementation in cardiovascular imaging is still rare despite increasing research. We sought to facilitate discussion across several fields and across the lifecycle of research, development, validation, and implementation to identify challenges and opportunities to further translation of AI in cardiovascular imaging. Furthermore, it seemed apparent that a multidisciplinary effort across institutions would be essential to overcome these challenges. This paper summarizes the proceedings of the National Heart, Lung, and Blood Institute-led workshop, creating consensus around needs and opportunities for institutions at several levels to support and advance research in this field and support future translation., Competing Interests: Funding Support and Author Disclosures The content of this manuscript is solely the responsibility of the authors and does not necessarily reflect the official views of the National Heart, Lung, and Blood Institute, National Institutes of Health, or the United States Department of Health and Human Services.

Background: The majority of patients with heart failure with preserved ejection fraction (HFpEF) have the obesity phenotype, but no therapies specifically targeting obesity in HFpEF exist., Objectives: The aim of this study was to describe the design and baseline characteristics of 2 trials of semaglutide, a glucagon-like peptide-1 receptor agonist, in patients with the obesity HFpEF phenotype: STEP-HFpEF (Semaglutide Treatment Effect in People with obesity and HFpEF; NCT04788511) and STEP-HFpEF DM (Semaglutide Treatment Effect in People with obesity and HFpEF and type 2 diabetes; NCT04916470)., Methods: Both STEP-HFpEF and STEP-HFpEF DM are international multicenter, double-blind, placebo-controlled trials that randomized adults with HFpEF and a body mass index ≥30 kg/m 2 to once-weekly semaglutide at a dose of 2.4 mg or placebo. Participants were eligible if they had a left ventricular ejection fraction (LVEF) ≥45%; NYHA functional class II to IV; a Kansas City Cardiomyopathy Questionnaire (KCCQ)-Clinical Summary Score (CSS) <90 points; and ≥1 of the following: elevated filling pressures, elevated natriuretic peptides plus structural echocardiographic abnormalities, recent heart failure hospitalization plus ongoing diuretic use, and/or structural abnormalities. The dual primary endpoints are the 52-week change in the KCCQ-CSS and body weight., Results: In STEP-HFpEF and STEP-HFpEF DM (N = 529 and N = 617, respectively), nearly half were women, and most had severe obesity (median body mass index of 37 kg/m 2 ) with typical features of HFpEF (median LVEF of 57%, frequent comorbidities, and elevated natriuretic peptides). Most participants received diuretic agents and renin-angiotensin blockers at baseline, and approximately one-third were on mineralocorticoid receptor antagonists. Sodium-glucose cotransporter-2 inhibitor use was rare in STEP-HFpEF but not in STEP HFpEF DM (32%). Patients in both trials had marked symptomatic and functional impairments (KCCQ-CSS ∼59 points, 6-minute walking distance ∼300 m)., Conclusions: In total, STEP-HFpEF program randomized 1,146 participants with the obesity phenotype of HFpEF and will determine whether semaglutide improves symptoms, physical limitations, and exercise function in addition to weight loss in this vulnerable group., Competing Interests: Funding Support and Author Disclosures The STEP-HFpEF and STEP-HFpEF DM trials were funded by Novo Nordisk.

Background: Many patients with heart failure and preserved ejection fraction have no overt volume overload and normal resting left atrial (LA) pressure., Objectives: This study sought to characterize patients with normal resting LA pressure (pulmonary capillary wedge pressure [PCWP] <15 mm Hg) but exercise-induced left atrial hypertension (EILAH)., Methods: The REDUCE LAP-HF II (A Study to Evaluate the Corvia Medical, Inc. IASD System II to Reduce Elevated Left Atrial Pressure in Patients With Heart Failure) trial randomized 626 patients with ejection fraction ≥40% and exercise PCWP ≥25 mm Hg to atrial shunt or sham procedure. The primary trial outcome, a hierarchical composite of death, heart failure hospitalization, intensification of diuretics, and change in health status was compared between patients with EILAH and those with heart failure and resting left atrial hypertension (RELAH)., Results: Patients with EILAH (29%) had similar symptom severity, but lower natriuretic peptide levels, higher 6-minute walk distance, less atrial fibrillation, lower left ventricular mass, smaller LA volumes, lower E/e', and better LA strain. PCWP was lower at rest, but had a larger increase with exercise in EILAH. Neither group as a whole had a significant effect from shunt therapy vs sham. Patients with EILAH were more likely to have characteristics associated with atrial shunt responsiveness (peak exercise pulmonary vascular resistance <1.74 WU) and no pacemaker (63% vs 46%; P < 0.001). The win ratio for the primary outcome was 1.56 (P = 0.08) in patients with EILAH and 1.51 (P = 0.04) in those with RELAH when responder characteristics were present., Conclusions: Patients with EILAH had similar symptom severity but less advanced myocardial and pulmonary vascular disease. This important subgroup may be difficult to diagnose without invasive exercise hemodynamics, but it has characteristics associated with favorable response to atrial shunt therapy.

Background: Systemic microvascular dysfunction and inflammation are postulated to play a pathophysiologic role in heart failure with preserved ejection fraction (HFpEF)., Objectives: This study aimed to identify biomarker profiles associated with clinical outcomes in HFpEF and investigate how inhibition of the neutrophil-derived reactive oxygen species-producing enzyme, myeloperoxidase, affects these biomarkers., Methods: Using supervised principal component analyses, the investigators assessed the associations between baseline plasma proteomic Olink biomarkers and clinical outcomes in 3 independent observational HFpEF cohorts (n = 86, n = 216, and n = 242). These profiles were then compared with the biomarker profiles discriminating patients treated with active drug vs placebo in SATELLITE (Safety and Tolerability Study of AZD4831 in Patients With Heart Failure), a double-blind randomized 3-month trial evaluating safety and tolerability of the myeloperoxidase inhibitor AZD4831 in HFpEF (n = 41). Pathophysiological pathways were inferred from the biomarker profiles by interrogation of the Ingenuity Knowledge Database., Results: TNF-R1, TRAIL-R2, GDF15, U-PAR, and ADM were the top individual biomarkers associated with heart failure hospitalization or death, and FABP4, HGF, RARRES2, CSTB, and FGF23 were associated with lower functional capacity and poorer quality of life. AZD4831 downregulated many markers (most significantly CDCP1, PRELP, CX3CL1, LIFR, VSIG2). There was remarkable consistency among pathways associated with clinical outcomes in the observational HFpEF cohorts, the top canonical pathways being associated with tumor microenvironments, wound healing signaling, and cardiac hypertrophy signaling. These pathways were predicted to be downregulated in AZD4831 relative to placebo-treated patients., Conclusions: Biomarker pathways that were most strongly associated with clinical outcomes were also the ones reduced by AZD4831.

Background: Black people have a higher incidence and prevalence of heart failure (HF) than White people, and once HF has developed, they may have worse outcomes. There is also evidence that the response to several pharmacologic therapies may differ between Black and White patients., Objectives: The authors sought to examine the outcomes and response to treatment with dapagliflozin according to Black or White race in a pooled analysis of 2 trials comparing dapagliflozin to placebo in patients with heart failure with reduced ejection fraction (DAPA-HF [Dapagliflozin and Prevention of Adverse Outcomes in Heart Failure]) and heart failure with mildly reduced ejection fraction/heart failure with preserved ejection fraction (DELIVER [Dapagliflozin Evaluation to Improve the Lives of Patients With Preserved Ejection Fraction Heart Failure])., Methods: Because most self-identified Black patients were enrolled in the Americas, the comparator group was White patients randomized in the same regions. The primary outcome was the composite of worsening HF or cardiovascular death., Results: Of the 3,526 patients randomized in the Americas, 2,626 (74.5%) identified as White and 381 (10.8%) as Black. The primary outcome occurred at a rate of 16.8 (95% CI: 13.8-20.4) in Black patients compared with 11.6 (95% CI: 10.6-12.7) per 100 person-years in White patients (adjusted HR: 1.27; 95% CI: 1.01-1.59). Compared with placebo, dapagliflozin decreased the risk of the primary endpoint to the same extent in Black (HR: 0.69; 95% CI: 0.47-1.02) and White patients (HR: 0.73 [95% CI: 0.61-0.88]; P interaction  = 0.73). The number of patients needed to treat with dapagliflozin to prevent one event over the median follow-up was 17 in White and 12 in Black patients. The beneficial effects and favorable safety profile of dapagliflozin were consistent across the range of left ventricular ejection fractions in both Black and White patients., Conclusions: The relative benefits of dapagliflozin were consistent in Black and White patients across the range of left ventricular ejection fraction, with greater absolute benefits in Black patients.

Background: Optimizing systolic blood pressure (SBP) in heart failure (HF) with preserved ejection fraction carries a Class I recommendation but with limited evidence. Sodium-glucose cotransporter 2 (SGLT2) inhibitors have antihypertensive effects across cardiovascular disease., Objectives: The authors examined the interplay between SBP and treatment effects of dapagliflozin on SBP and cardiovascular outcomes., Methods: The authors analyzed 6,263 DELIVER (Dapagliflozin Evaluation to Improve the LIVEs of Patients With PReserved Ejection Fraction Heart Failure) participants and related baseline and mean achieved SBP categories (<120, 120-129, 130-139, ≥140 mm Hg) to the primary outcome (cardiovascular death or worsening HF), secondary outcomes, and safety events. They analyzed whether the blood pressure-lowering effects of dapagliflozin accounted for its treatment effects by adjusting for the change in SBP from baseline to 1 month., Results: The average age was 72 ± 10 years and 44% were women. SBP <120 mm Hg was associated with higher HF and mortality events, although amputation and stroke risk increased with higher SBP. Dapagliflozin reduced SBP by 1.8 (95% CI: 1.1-2.5) mm Hg compared with placebo at 1 month. The treatment effect of dapagliflozin on the primary outcome and Kansas City Cardiomyopathy Questionnaire total symptom score was consistent across SBP (interaction P = 0.15 and P = 0.98, respectively). Adverse events between arms were similar across SBP categories. The treatment effect was not accounted for by reducing blood pressure., Conclusions: In DELIVER, risk by SBP was augmented in the lowest and highest categories and varied by endpoint examined. Dapagliflozin modestly decreased SBP compared with placebo. Dapagliflozin was similarly efficacious and safe across the range of baseline SBP. The beneficial effects of dapagliflozin were not accounted for the changes in SBP.

Background: N-terminal pro-B-type natriuretic peptide (NT-proBNP) is used for diagnostic and prognostic evaluation in heart failure (HF). Previous clinical trials in heart failure with mildly reduced ejection fraction (HFmrEF) or heart failure with preserved ejection fraction (HFpEF) have shown potential heterogeneity in the treatment response by baseline NT-proBNP levels., Objectives: The purpose of this study was to assess the treatment effect of dapagliflozin across baseline levels of NT-proBNP among patients with HFmrEF or HFpEF., Methods: This was a post hoc analysis from DELIVER (Dapagliflozin Evaluation to Improve the LIVEs of Patients With PReserved Ejection Fraction Heart Failure), a randomized, placebo-controlled trial of dapagliflozin in patients with HFmrEF or HFpEF. Elevated NT-proBNP was part of the inclusion criteria (≥300 ng/L for non-atrial fibrillation or flutter [AFF]; ≥600 ng/L for AFF). Baseline NT-proBNP was categorized in quartiles and additionally analyzed continuously. The primary composite outcome was cardiovascular death or worsening HF events., Results: Among the 6,262 included patients (mean: 71.7 years and 3,516 [56%] men), the median baseline concentration of NT-proBNP was 716 (Q1-Q3: 469-1,280) ng/L and 1,399 (Q1-Q3: 962-2,212) ng/L for non-AFF and AFF, respectively. Higher NT-proBNP levels were linearly associated with a greater risk of the primary outcome (adjusted HR for log 2 NTpro-BNP was 1.53 [95% CI: 1.46-1.62] and Q4 vs Q1: 3.46 [95% CI: 2.48-4.22]; P < 0.001), with consistent results regardless of AFF status. The clinical benefit of dapagliflozin was present irrespective of baseline NT-proBNP concentration (P value for interaction = 0.40 by quartiles and = 0.19 continuously for the primary outcome) and the absolute risk reduction was, therefore, greater with higher NT-proBNP concentrations. The effect on health status and safety of dapagliflozin was similarly consistent across NT-proBNP quartiles., Conclusions: Dapagliflozin is safe and improves outcomes irrespective of baseline NT-proBNP concentrations in HFmrEF or HFpEF, with the greatest absolute benefit likely seen in patients with higher NT-proBNP concentrations.

Background: Ablation of the right-sided greater splanchnic nerve (GSN) can reduce excessive splanchnic vasoconstriction, potentially improving the handling of volume shifts in patients with heart failure with preserved ejection fraction (HFpEF)., Objectives: The purpose of this study was to assess a novel catheter procedure of right-sided GSN ablation to treat HFpEF: splanchnic ablation for volume management., Methods: This trial included 11 HFpEF patients (8 women, age 70 ± 8 years) with New York Heart Association functional class II or III symptoms, ejection fraction ≥50%, and elevated pulmonary capillary wedge pressure at rest or with exercise. After splanchnic ablation for volume management, follow-up at 1, 3, 6, and 12 months included 6-minute walk test, Kansas City Cardiomyopathy Questionnaire (KCCQ), and echocardiography., Results: There were no device-related adverse cardiac events or clinical sequelae following right GSN ablation through 12 months. Patients experienced clinical improvements by 1 month that were sustained through 12 months. KCCQ score improved from baseline median 48 (IQR: 35-52) to 65 (IQR: 58-77) at 1 month and 80 (IQR: 77-88) at 12 months (P &lt; 0.05). The 6-minute walk test distance increased from baseline 292 ± 82 m to 341 ± 88 m at 1 month and 359 ± 75 m at 12 months (P &lt; 0.05). The NT-proBNP decreased from a baseline mean of 1,292 ± 1,186 pg/mL to 1,202 ± 797 pg/mL (P = 0.585) at 1 month, to 472 ± 226 pg/mL (P = 0.028) at 6 months, and to 379 ± 165 pg/mL (P = 0.039) at 12 months., Conclusions: In this open-label, single-arm feasibility study, right-sided GSN ablation was safe and improved mostly subjective clinical metrics in patients with HFpEF over 12 months.

Heart failure with preserved ejection fraction is associated with elevated left atrial pressure during exercise. Sodium-glucose cotransporter-2 inhibitors have demonstrated the evidence of benefit in heart failure with preserved ejection fraction, but even with this treatment, heart failure hospitalizations remain high, and improvements in quality of life scores are modest. Thus, there is growing interest in nonpharmacological methods of limiting the rise in left atrial pressure during exertion. Creation of an interatrial shunt (IAS) may unload the left heart during exercise. Multiple implant or nonimplant IAS procedures are under investigation. Implantation of the most studied device results in 3 to 5 mm Hg decreases in pulmonary capillary wedge pressure during exercise, no increase in incidence of stroke, stable increases in Qp/Qs (1.2-1.3), and mild right heart enlargement without change in function out to at least a year after treatment. The findings from the first large randomized controlled trial of an atrial shunt have recently been published. For the population as a whole, implantation of the atrial shunt device appeared to be safe but did not provide clinical benefit. However, prespecified and post-hoc analyses have demonstrated that men, patients with larger right atrial volumes, and those with pulmonary artery systolic pressure >70 mm Hg at 20 W exercise had worse outcomes with IAS therapy, whereas those with peak exercise pulmonary vascular resistance <1.74 Wood units and absence of a pacemaker represented a potential responder group. Here, we summarize the results of the published data and the current IAS therapies under investigation. We also highlight unanswered questions in this field of inquiry., Competing Interests: S.E.L. is on an events adjudication committee for CVRx and is a consultant for Axon Therapies, Novartis, Alleviant, Eli Lilly, and Occlutech.

Background: SGLT2 inhibitors are strongly recommended in guidelines to treat patients with heart failure with reduced ejection fraction, but their clinical benefits at higher ejection fractions are less well established. Two large-scale trials, DELIVER and EMPEROR-Preserved, in heart failure with mildly reduced or preserved ejection fraction have been done, providing power to examine therapeutic effects on cardiovascular mortality and in patient subgroups when combined with the earlier trials in reduced ejection fraction., Methods: We did a prespecified meta-analysis of DELIVER and EMPEROR-Preserved, and subsequently included trials that enrolled patients with reduced ejection fraction (DAPA-HF and EMPEROR-Reduced) and those admitted to hospital with worsening heart failure, irrespective of ejection fraction (SOLOIST-WHF). Using trial-level data with harmonised endpoint definitions, we did a fixed-effects meta-analysis to estimate the effect of SGLT2 inhibitors on various clinical endpoints in heart failure The primary endpoint for this meta-analysis was time from randomisation to the occurrence of the composite of cardiovascular death or hospitalisation for heart failure. We assessed heterogeneity in treatment effects for the primary endpoint across subgroups of interest. This study is registered with PROSPERO, CRD42022327527., Findings: Among 12 251 participants from DELIVER and EMPEROR-Preserved, SGLT2 inhibitors reduced composite cardiovascular death or first hospitalisation for heart failure (hazard ratio 0·80 [95% CI 0·73-0·87]) with consistent reductions in both components: cardiovascular death (0·88 [0·77-1·00]) and first hospitalisation for heart failure (0·74 [0·67-0·83]). In the broader context of the five trials of 21 947 participants, SGLT2 inhibitors reduced the risk of composite cardiovascular death or hospitalisation for heart failure (0·77 [0·72-0·82]), cardiovascular death (0·87 [0·79-0·95]), first hospitalisation for heart failure (0·72 [0·67-0·78]), and all-cause mortality (0·92 [0·86-0·99]). These treatment effects for each of the studied endpoints were consistently observed in both the trials of heart failure with mildly reduced or preserved ejection fraction and across all five trials. Treatment effects on the primary endpoint were generally consistent across the 14 subgroups examined, including ejection fraction., Interpretation: SGLT2 inhibitors reduced the risk of cardiovascular death and hospitalisations for heart failure in a broad range of patients with heart failure, supporting their role as a foundational therapy for heart failure, irrespective of ejection fraction or care setting., Funding: None., Competing Interests: Declaration of interests MV has received research grant support or served on advisory boards for American Regent, Amgen, AstraZeneca, Bayer, Baxter Healthcare, Boehringer Ingelheim, Cytokinetics, Lexicon Pharmaceuticals, Novartis, Pharmacosmos, Relypsa, Roche Diagnostics, and Sanofi; received speaker fees from AstraZeneca, Novartis, and Roche Diagnostics; and participates on clinical trial committees for studies sponsored by Galmed, Novartis, Bayer, Occlutech, and Impulse Dynamics.

Objectives: In this study, the authors sought to assess the relationship between AFF and outcomes, the treatment response to sacubitril/valsartan and first-detected AFF in patients with HFpEF enrolled in the PARAGON-HF trial., Background: Atrial fibrillation and flutter (AFF) are common in heart failure with preserved ejection fraction (HFpEF) and increase the risk of adverse outcomes., Methods: A total of 4,776 patients formed 3 groups: those with AFF according to electrocardiography (ECG) at enrollment (n = 1,552; 33%), those with history of AFF but without AFF on ECG at enrollment (n = 1,005; 21%), and those without history of AFF or AFF on ECG at enrollment (n = 2,219, 46%). We assessed outcomes, treatment response to sacubitril/valsartan in each group, and the risk associated with first-detected AFF in patients without any known AFF. The primary outcome was a composite of total heart failure hospitalizations and cardiovascular death., Results: History of AFF and AFF at enrollment were associated with higher risk of the primary outcome (risk ratio [RR]: 1.36 [95% CI: 1.12-1.65] and RR: 1.31 [1.11-1.54], respectively), than no AFF. Neither history of AFF nor AFF at enrollment modified the treatment effect of sacubitril/valsartan. Post randomization AFF occurred in 12% of patients without previous AFF and was associated with 2.8-fold higher risk of the primary outcome, but it was not influenced by sacubitril/valsartan., Conclusions: History of AFF and AFF on ECG at enrollment were associated with a higher risk of the primary outcome. First-detected AFF was not influenced by sacubitril/valsartan, yet it was associated with increased risk of all subsequent outcomes and may represent a potential target for future HFpEF trials.

Background: Placement of an interatrial shunt device reduces pulmonary capillary wedge pressure during exercise in patients with heart failure and preserved or mildly reduced ejection fraction. We aimed to investigate whether an interatrial shunt can reduce heart failure events or improve health status in these patients., Methods: In this randomised, international, blinded, sham-controlled trial performed at 89 health-care centres, we included patients (aged ≥40 years) with symptomatic heart failure, an ejection fraction of at least 40%, and pulmonary capillary wedge pressure during exercise of at least 25 mm Hg while exceeding right atrial pressure by at least 5 mm Hg. Patients were randomly assigned (1:1) to receive either a shunt device or sham procedure. Patients and outcome assessors were masked to randomisation. The primary endpoint was a hierarchical composite of cardiovascular death or non-fatal ischemic stroke at 12 months, rate of total heart failure events up to 24 months, and change in Kansas City Cardiomyopathy Questionnaire overall summary score at 12 months. Pre-specified subgroup analyses were conducted for the heart failure event endpoint. Analysis of the primary endpoint, all other efficacy endpoints, and safety endpoints was conducted in the modified intention-to-treat population, defined as all patients randomly allocated to receive treatment, excluding those found to be ineligible after randomisation and therefore not treated. This study is registered with ClinicalTrials.gov, NCT03088033., Findings: Between May 25, 2017, and July 24, 2020, 1072 participants were enrolled, of whom 626 were randomly assigned to either the atrial shunt device (n=314) or sham procedure (n=312). There were no differences between groups in the primary composite endpoint (win ratio 1·0 [95% CI 0·8-1·2]; p=0·85) or in the individual components of the primary endpoint. The prespecified subgroups demonstrating a differential effect of atrial shunt device treatment on heart failure events were pulmonary artery systolic pressure at 20W of exercise (p interaction =0·002 [>70 mm Hg associated with worse outcomes]), right atrial volume index (p interaction =0·012 [≥29·7 mL/m 2 , worse outcomes]), and sex (p interaction =0·02 [men, worse outcomes]). There were no differences in the composite safety endpoint between the two groups (n=116 [38%] for shunt device vs n=97 [31%] for sham procedure; p=0·11)., Interpretation: Placement of an atrial shunt device did not reduce the total rate of heart failure events or improve health status in the overall population of patients with heart failure and ejection fraction of greater than or equal to 40%., Funding: Corvia Medical., Competing Interests: Declaration of interests SJS reports research grants from the National Institutes of Health (NIH; U54 HL160273, R01 HL107577, R01 HL127028, R01 HL140731, and R01 HL149423), Actelion, AstraZeneca, Corvia, Novartis, and Pfizer; and personal fees from Abbott, Actelion, AstraZeneca, Amgen, Aria CV, Axon Therapies, Bayer, Boehringer-Ingelheim, Boston Scientific, Bristol Myers Squibb, Cardiora, Coridea, CVRx, Cyclerion, Cytokinetics, Edwards Lifesciences, Eidos, Eisai, Imara, Impulse Dynamics, Intellia, Ionis, Ironwood, Lilly, Merck, MyoKardia, Novartis, Novo Nordisk, Pfizer, Prothena, Regeneron, Rivus, Sanofi, Shifamed, Tenax, Tenaya, and United Therapeutics.

Objectives: This report describes the baseline clinical profiles and management of DELIVER (Dapagliflozin Evaluation to Improve the Lives of Patients With Preserved Ejection Fraction Heart Failure) trial participants and how these compare with those in other contemporary heart failure with preserved ejection fraction trials., Background: The DELIVER trial was designed to evaluate the effects of the sodium-glucose cotransporter-2 inhibitor dapagliflozin on cardiovascular death, heart failure (HF) hospitalization, or urgent HF visits in patients with HF with mildly reduced and preserved left ventricular ejection fraction (LVEF)., Methods: Adults with symptomatic HF and LVEF >40%, with or without type 2 diabetes mellitus, elevated N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels, and evidence of structural heart disease were randomized to dapagliflozin 10 mg once daily or matching placebo., Results: A total of 6,263 patients were randomized (mean age: 72 ± 10 years; 44% women; 45% type 2 diabetes mellitus; 45% with body mass index ≥30 kg/m 2 ; and 57% with history of atrial fibrillation or flutter). Most participants had New York Heart Association functional class II symptoms (75%). Baseline mean LVEF was 54.2 ± 8.8% and median NT-proBNP of 1,399 pg/mL (IQR: 962 to 2,210 pg/mL) for patients in atrial fibrillation/flutter compared with 716 pg/mL (IQR: 469 to 1,281 pg/mL) in those who were not. Patients in both hospitalized and ambulatory settings were enrolled, including 10% enrolled in-hospital or within 30 days of a hospitalization for HF. Eighteen percent of participants had HF with improved LVEF., Conclusions: DELIVER is the largest and broadest clinical trial of this population to date and enrolled high-risk, well-treated patients with HF with mildly reduced and preserved LVEF.

Background: The transition from hospital to home is a vulnerable period for all patients, particularly for those who have limited English proficiency (LEP)., Methods: The research team retrospectively studied adults discharged home from a hospital in 2018-2019 to determine the association of LEP with (1) reach of a care transitions outreach program phone call (automated call within three days after discharge or a subsequent manual phone call) and (2) postdischarge issues reported on the phone calls. All results were adjusted for measured confounders; associations using predicted probabilities and average marginal effects were described., Results: A total of 13,860 patients were included, and 11.3% had LEP. After adjustment, the program reached most patients regardless of LEP status; automated calls were more likely to reach English proficient patients (81.1% vs. 75.6%, p < 0.01), and when the automated call was unsuccessful, manual calls were more likely to reach LEP patients (47.8% vs. 28.3%, p < 0.001). After adjustment, patients with LEP reported more difficulty with all measured issues: understanding discharge instructions (11.3% vs. 6.5%), obtaining prescriptions (8.3% vs. 5.5%), medication concerns (12.9% vs. 10.6%), follow-up questions (16.1% vs. 13.3%), new or worsening symptoms (15.1% vs. 11.9%), and any other clinical issues (16.6% vs. 13.0%); p < 0.05 for all comparisons., Conclusion: Although reach was high for the care transitions program, among patients with LEP, important disparities exist in patient-reported postdischarge issues. These results indicate the need for better discharge processes that focus on communication quality and health equity., (Copyright © 2021 The Joint Commission. Published by Elsevier Inc.

Objectives: This study investigated an enriched cohort of patients with heart failure and preserved ejection fraction (HFpEF) in TOPCAT (Treatment of Preserved Cardiac Function Heart Failure With an Aldosterone Antagonist) with an echocardiographic phenotype of cardiac amyloidosis., Background: There is a high prevalence of increased interventricular septal (IVS) thickness and decreased mitral annular systolic (s') velocity in cardiac amyloidosis. In addition, clinical trials of neurohormonal blockade are missing in this population., Methods: TOPCAT randomized patients with HFpEF to spironolactone or placebo therapy with a primary endpoint of cardiovascular death, HF hospitalization, or aborted cardiac arrest. Patients with IVS and s' velocity measurements were included, and adjusted Cox models assessed the effect of echocardiographic variables and spironolactone on the primary endpoint., Results: Among 590 patients, mean s' velocity was 6.4 ± 2.1 cm/s and IVS thickness was 1.2 ± 0.2 cm. The enriched cohort with characteristics of cardiac amyloidosis (s' velocity ≤6 cm/s and IVS thickness ≥1.2 cm) included 135 patients (23% of the cohort). After a median follow-up of 2.6 years (1.5-3.9 years), these patients had the worst prognosis (adjusted HR: 2.10; 95% CI: 1.26-3.50; P = 0.004). Both s' velocity and IVS thickness were individually associated with the primary endpoint, and abnormalities in these parameters were additive as lower s' velocity was particularly prognostic in those with greater IVS thickness (interaction: P = 0.013). Spironolactone was associated with improved outcomes in the overall cohort (P = 0.024), and patients in the enriched cohort had a benefit similar to that in other groups (interaction: P = 0.382)., Conclusions: An enriched subset of patients with structural and functional echocardiographic features of cardiac amyloidosis had the worst prognosis in the TOPCAT study, but they benefitted similarly from spironolactone therapy.

Objectives: The purpose of this study was to evaluate the effects of intravenous levosimendan on hemodynamics and 6-min walk distance (6MWD) in patients with pulmonary hypertension and heart failure with preserved ejection fraction (PH-HFpEF)., Background: There are no proven effective treatments for patients with PH-HFpEF., Methods: Patients with mean pulmonary artery pressure (mPAP) ≥35 mm Hg, pulmonary capillary wedge pressure (PCWP) ≥20 mm Hg, and LVEF ≥40% underwent 6MWD and hemodynamic measurements at rest, during passive leg raise, and supine cycle exercise at baseline and after an open-label 24-h levosimendan infusion (0.1 μg/kg/min). Hemodynamic responders (those with ≥4 mm Hg reduction of exercise-PCWP) were randomized (double blind) to weekly levosimendan infusion (0.075 to 0.1 ug/kg/min for 24 h) or placebo for 5 additional weeks. The primary end point was exercise-PCWP, and key secondary end points included 6MWD and PCWP measured across all exercise stages., Results: Thirty-seven of 44 patients (84%) met responder criteria and were randomized to levosimendan (n = 18) or placebo (n = 19). Participants were 69 ± 9 years of age, 61% female, and with resting mPAP 41.0 ± 9.3 mm Hg and exercise-PCWP 36.8 ± 11.3 mm Hg. Compared with placebo, levosimendan did not significantly reduce the primary end point of exercise-PCWP at 6 weeks (-1.4 mm Hg; 95% confidence interval [CI]: -7.8 to 4.8; p = 0.65). However, levosimendan reduced PCWP measured across all exercise stages (-3.9 ± 2.0 mm Hg; p = 0.047). Levosimendan treatment resulted in a 29.3 m (95% CI: 2.5 to 56.1; p = 0.033) improvement in 6MWD compared with placebo., Conclusions: Six weeks of once-weekly levosimendan infusion did not affect exercise-PCWP but did reduce PCWP incorporating data from rest and exercise, in tandem with increased 6MWD. Further study of levosimendan is warranted as a therapeutic option for PH-HFpEF.

Objectives: This study investigated the prognostic importance of heart failure (HF) signs and symptoms in patients with heart failure and preserved ejection fraction (HFpEF), and the effect of sacubitril/valsartan on HF signs and symptoms., Background: In patients with HFpEF, worsening of HF symptoms, as a marker of cardiac decompensation, is frequently the reason for hospitalization. In this heterogenous disease entity, the prognostic value of HF signs and symptoms with regard to cardiovascular (CV) outcomes is poorly defined., Methods: The authors examined the association between baseline HF signs and symptoms (rest dyspnea, exertional dyspnea, paroxysmal nocturnal dyspnea, orthopnea, fatigue, edema, jugular venous distension, rales, and third heart sound) as well as burden of these HF signs and symptoms (classified as ≤2 and ≥3 HF signs and symptoms) and the primary composite of total HF hospitalizations and CV death, its components, and all-cause death in 4,725 patients enrolled in PARAGON-HF (Prospective Comparison of ARNI With ARB Global Outcomes in HFpEF) with available signs and symptoms at randomization. Response to sacubitril/valsartan on the basis of the presence of signs and symptoms was evaluated. Effects of sacubitril/valsartan on signs and symptoms over time were assessed using binary repeated-measures logistic regression., Results: Patients with high (≥3) burden of HF signs and symptoms (n = 1,772 [38%]) were more commonly women, had slightly lower left ventricular ejection fractions, higher body mass index, and more advanced New York Heart Association functional class compared with patients with low (≤2) burden (n = 2,953 [62%]) (p < 0.001 for all). Levels of N-terminal pro-B-type natriuretic peptide did not differ significantly between groups (p = 0.14). Greater burden of signs and symptoms was associated with higher risk for total HF hospitalizations and CV death (rate ratio [RR]: 1.50; 95% confidence interval [CI]: 1.30 to 1.74) and all-cause death (RR: 1.41; 95% CI: 1.21 to 1.65). Among individual signs and symptoms, orthopnea (RR: 1.29; 95% CI: 1.04 to 1.61) and rales (RR: 1.52; 95% CI: 1.10 to 2.10) were most predictive of the primary endpoint. Treatment response to sacubitril/valsartan was not significantly modified by burden of HF signs and symptoms (p for interaction = 0.08), though patients with orthopnea appeared to derive greater benefit from sacubitril/valsartan (RR: 0.67; 95% CI: 0.49 to 0.90) than those without orthopnea (RR: 0.97; 95% CI: 0.82 to 1.14; p for interaction = 0.04). Compared with valsartan, sacubitril/valsartan did not significantly decrease overall burden of HF signs and symptoms over time (odds ratio: 0.84; 95% CI: 0.67 to 1.07) but did reduce exertional dyspnea (odds ratio: 0.76; 95% CI: 0.63 to 0.93)., Conclusions: High burden of HF signs and symptoms, particularly the presence of orthopnea and rales, portends a higher risk for adverse CV events in patients with HF with preserved ejection fraction. Sacubitril/valsartan did not significantly decrease the burden of HF signs and symptoms over time but did reduce exertional dyspnea relative to valsartan.

Purpose: HPV-positive oropharyngeal squamous cell carcinoma (OPSCC) carries a favorable prognosis for patients, yet nearly 30% of patients will experience disease relapse. We sought to detail patterns of failure, associated salvage therapy, and outcomes for patients with recurrent HPV-positive OPSCC., Methods and Materials: This is a single institution retrospective study of patients with recurrent HPV-positive OPSCC irradiated from 2002 to 2014. The primary study outcome was overall survival (OS, calculated using the Kaplan-Meier method). Secondary aims included patterns of first failure with descriptive details of salvage therapy. Solitary recurrences were defined as initial presentation of recurrence in a single site (primary, neck or oligometastatic), and multi-site was defined as local and regional and/or multiple sites of distant recurrence. Survival outcomes were compared using the log-rank test., Results: The cohort consisted of 132 patients. The median follow-up was 59 months for surviving patients. Estimated 2-year and 5-year OS rates were 47% and 32%, respectively. Comparative 2-year and 5-year OS rates were 65% and 46% versus 19% and 9% for the solitary group and multi-site group, respectively (p < .001)., Conclusions: Patients with recurrent HPV-positive OPSCC experience 5-year survival of approximately 32%. However, patients with a "solitary" recurrence including disease at the primary site, neck or oligometastatic site have more favorable long-term outcomes., (Copyright © 2020 Elsevier Ltd.

Objectives: This study prospectively evaluated endomyocardial biopsies in patients with heart failure with preserved ejection fraction (HFpEF) to identify histopathologic phenotypes and their association with clinical characteristics., Background: Myocardial tissue analysis from a prospectively defined HFpEF cohort reflecting contemporary comorbidities is lacking., Methods: Patients with HFpEF (EF ≥50%) referred to the Johns Hopkins HFpEF Clinic between August 2014 and September 2018 were enrolled for right heart catheterization and endomyocardial biopsy. Clinical features, echocardiography, hemodynamics, and tissue histology were determined and compared with controls (unused donor hearts) and HF with reduced EF (HFrEF)., Results: Of the 108 patients enrolled, median age was 66 years (25th to 75th percentile: 57 to 74 years), 61% were women, 57% were African American, 62% had a previous HF hospitalization, median systolic blood pressure was 141 mm Hg (25th to 75th percentile: 125 to 162 mm Hg), body mass index (BMI) was 37 kg/m 2 (25th to 75th percentile: 32 to 45 kg/m 2 ), and 97% were on a loop diuretic. Myocardial fibrosis and myocyte hypertrophy were often present (93% and 88%, respectively); however, mild in 71% with fibrosis and in 52% with hypertrophy. Monocyte infiltration (CD68+ cells/mm 2 ) was greater in patients with HFpEF versus controls (60.4 cells/mm 2 [25th to 75th percentile: 36.8 to 97.8] vs. 32.1 cells/mm 2 [25th to 75th percentile: 22.3 to 59.2]; p = 0.02) and correlated with age and renal disease. Cardiac amyloidosis (CA) was diagnosed in 15 (14%) patients (HFpEF-CA: 7 patients with wild-type transthyretin amyloidosis [ATTR], 4 patients with hereditary ATTR, 3 patients with light-chain amyloidosis, and 1 patient with AA (secondary) amyloidosis), of which 7 cases were unsuspected. Patients with HFpEF-CA were older, with lower BMI, higher left ventricular mass index, and higher N-terminal pro-B-type natriuretic peptide and troponin I levels., Conclusions: In this large, prospective myocardial tissue analysis of HFpEF, myocardial fibrosis and hypertrophy were common, CD68+ inflammation was increased, and CA prevalence was 14%. Tissue analysis in HFpEF might improve precision therapies by identifying relevant myocardial mechanisms., (Copyright © 2020. Published by Elsevier Inc.)

It is highly desired to develop an efficient large surface area CoCrFeO 4 -based beads sun-light driven photocatalysts with excellent recycling features for degrading high-concentration dyes. Herein, a novel CoCrFeO 4 oxide nanoparticles have customarily been synthesized by the combination of three metals (Co, Cr and Fe) via co-precipitation method in aqueous solution and then millimeter-scale CoCrFeO 4 oxide chitosan-composite beads (CoCrFeO 4 -CB) were prepared by incorporating the CoCrFeO 4 in chitosan polymer in basic medium, which makes the adsorbent easier to separate. The number of optimized nanocomposite beads used for the removal of high-concentration dyes displays 5-time photoactivity enhancement under sun-light irradiation compared to pristine CoCrFeO 4 . Based on the fluorescence spectra related to the formed OH amounts, temperature-programmed desorption and electrochemical results, it is deduced that the unprecedented photocatalytic activities are mainly attributed to the large surface area, and enhanced charge separation from the chitosan as well as its promotion effects on O 2 activation. Influencing factors that effect the photocatalytic efficiency of dyes, such as catalyst dose, dyes concentration, time, and the light source was also studied. More importantly, after five catalytic cycles, no evident deactivation was observed, suggesting the satisfactory stability of the investigated photocatalyst. Also, large numbers of superoxides radicals form which is the main active species participate in the degradation of acid black were analyzed using a radical trapping experiment. It is expected that our work could render navigated information for steering toward the design and applications of the CoCrFeO 4 -based photocatalyst with sun-light utilization for environmental remediation., Competing Interests: Declaration of competing interest There are no conflicts of interest to be declared or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2020.

Objectives: The authors investigated the relationship between past or incident myocardial infarction (MI) and cardiovascular (CV) events in heart failure with preserved ejection fraction (HFpEF)., Background: MI and HFpEF share some common risk factors. The prognostic significance of MI in patients with HFpEF is uncertain., Methods: The authors pooled data from 3 trials-CHARM Preserved (Candesartan Cilexietil in Heart Failure Assessment of Reduction in Mortality and Morbidity), I-Preserve (Irbesartan in Heart Failure With Preserved Systolic Function), and the Americas region of TOPCAT (Treatment of Preserved Cardiac Function Heart Failure With an Aldosterone Antagonist) (N = 8,916)-and examined whether MI before or following enrollment independently predicted CV death and heart failure (HF) hospitalization., Results: At baseline, 2,668 patients (30%) had history of MI. Prior MI was independently associated with greater risk of CV death (4.7 vs. 3.5 events/100 patient-years [py], adjusted hazard ratio [HR]: 1.42 [95% confidence interval (CI): 1.23 to 1.64]; p < 0.001). Excess sudden death drove this difference (1.9 vs. 1.2 events/100 py, adjusted HR: 1.55 [95% CI: 1.23 to 1.97]; p < 0.001). There was no difference in HF hospitalization (5.9 vs. 5.5 events/100 py, adjusted HR: 1.05, 95% CI: 0.92 to 1.19) or HF death by prior MI. During follow-up, MI occurred in 336 patients (3.8%). Risk of CV death increased 31-fold in the first 30 days after first post-enrollment MI, and remained 58% higher beyond 1 year after MI. Risk of first or recurrent HF hospitalization increased 2.4-fold after MI., Conclusions: Prior MI in HFpEF is associated with greater CV and sudden death but similar risk of HF outcomes. Patients with HFpEF who experience MI are at high risk of subsequent CV death and HF hospitalization. These data highlight the importance of primary and secondary prevention of MI in patients with HFpEF.

Objectives: The purpose of this study was to compare the risks of incident heart failure (HF) among a variety of chronic inflammatory diseases (CIDs) and to determine whether risks varied by severity of inflammation within each CID., Background: Individuals with CIDs are at elevated risk for cardiovascular diseases, but data are limited regarding risk for HF., Methods: An electronic health records database from a large urban medical system was examined, comparing individuals with CIDs with frequency-matched controls without CIDs, all of whom were receiving regular outpatient care. Rates of incident HF were determined by using the Kaplan-Meier method and subsequently used multivariate-adjusted proportional hazards models to compare HF risks for each CID. Exploratory analyses determined HF risks by proxy measurement of CID severity., Results: Of 37,636 patients (n = 18,278 patients with CIDs; and n = 19,358 controls without CIDs) there were 960 incident HF cases over a median of 3.6 years. Risks for incident HF were significantly or borderline significantly elevated for patients with systemic sclerosis (hazard ratio [HR]: 7.26; 95% confidence interval [CI]: 5.72 to 9.21; p < 0.01), systemic lupus erythematosus (HR: 3.15; 95% CI: 2.41 to 4.11; p < 0.01), rheumatoid arthritis (HR: 1.39; 95% CI: 1.13 to 1.71; p < 0.01), and human immunodeficiency virus (HR: 1.28; 95% CI: 0.99 to 1.66; p = 0.06). There was no association between psoriasis or inflammatory bowel disease and incident HF, although patients with those CIDs with higher levels of C-reactive protein had higher risks for HF than controls., Conclusions: Systemic sclerosis and systemic lupus erythematosus were associated with the highest risks of HF, followed by rheumatoid arthritis and HIV. Measurements of inflammation were associated with HF risk across different CIDs., (Copyright © 2020 American College of Cardiology Foundation. Published by Elsevier Inc. All rights reserved.)

Objectives: The authors sought to evaluate the prognostic significance of baseline N-terminal pro-B-type natriuretic peptide (NT-proBNP), whether NT-proBNP modified the treatment response to sacubitril/valsartan, and the treatment effect of sacubitril/valsartan on NT-proBNP overall and in key subgroups., Background: Sacubitril/valsartan reduces NT-proBNP in heart failure (HF) with both reduced and preserved ejection fraction (EF), but did not significantly reduce total HF hospitalizations and cardiovascular death compared with valsartan in patients with HF with preserved EF (HFpEF)., Methods: In the PARAGON-HF (Efficacy and Safety of LCZ696 Compared to Valsartan, on Morbidity and Mortality in Heart Failure Patients With Preserved Ejection Fraction) trial, 4,796 patients with HFpEF and elevated NT-proBNP were randomized to sacubitril/valsartan or valsartan. NT-proBNP was measured at screening in all patients and at 5 subsequent times in >2,700 patients: before, between, and after sequential valsartan and sacubitril/valsartan run-in periods, and 16 and 48 weeks post-randomization., Results: Median NT-proBNP was 911 pg/ml (interquartile range: 464 to 1,613 pg/ml) at screening. Screening NT-proBNP was strongly associated with the primary endpoint, total HF hospitalizations and cardiovascular death (rate ratio [RR]: 1.68 per log increase in NT-proBNP, 95% confidence interval [CI]: 1.53 to 1.85; p < 0.001). This relationship was stronger in patients with atrial fibrillation (adjusted RR: 2.33 [95% CI: 1.89 to 2.87] vs. 1.58 [95% CI: 1.42 to 1.75] in patients without atrial fibrillation; p interaction <0.001) and weaker in obese patients (adjusted RR: 1.50 [95% CI: 1.31 to 1.71] vs. 1.92 [95% CI: 1.70 to 2.17] in nonobese patients; p interaction <0.001). Screening NT-proBNP did not modify the treatment effect of sacubitril/valsartan compared with valsartan (p interaction = 0.96). Sacubitril/valsartan reduced NT-proBNP by 19% (95% CI: 14% to 23%; p < 0.001) compared with valsartan 16 weeks post-randomization, with similar reductions in men (20%) and women (18%), and in patients with left ventricular EF ≤57% (20%) and >57% (18%). Decreases in NT-proBNP predicted lower subsequent risk of the primary endpoint., Conclusions: Baseline NT-proBNP predicted HF events but did not modify the sacubitril/valsartan treatment effect in patients with HFpEF. Sacubitril/valsartan reduced NT-proBNP consistently in men and women, and in patients with lower or higher EF.

Objectives: The authors examined efficacy and safety of spironolactone by age in the Americas region (N = 1,767) of the TOPCAT (Treatment of Preserved Cardiac Function Heart Failure with an Aldosterone Antagonist) trial., Background: Heart failure with preserved ejection fraction disproportionately affects older adults who may exhibit changes in physiology and variable pharmacokinetics., Methods: TOPCAT enrolled patients with heart failure and a left ventricular ejection fraction ≥45% who were age 50 or older with an estimated glomerular filtration rate ≥30 mL/min/1.73 m 2 and prior heart failure hospitalization or elevated natriuretic peptide levels. Participants were randomized to spironolactone or placebo with a mean follow-up duration of 3.3 years. We assessed treatment effect and safety by protocol-defined age categories (<65, 65 to 74, and ≥75 years)., Results: The mean age was 72 ± 10 years (range 50 to 97 years) with 41% over the age of 75 years. Participants ≥75 years were more commonly women and white and had a lower body mass index and estimated glomerular filtration rate compared with the younger age categories. Spironolactone reduced the primary composite outcome compared with placebo across all age categories (p interaction = 0.42). However, spironolactone was associated with an increased risk of the safety endpoint (hazard ratio: 2.54; 95% confidence interval: 1.91 to 3.37; p < 0.001), particularly in older age groups (p interaction = 0.02). Findings in the whole TOPCAT cohort were consistent with results from the Americas region., Conclusions: In this post hoc, exploratory analysis of the TOPCAT trial data from the Americas region, although there was no effect of age on efficacy, there were considerable effects of age on increased rates of adverse safety outcomes. These results should be weighed when considering spironolactone for older heart failure with preserved ejection fraction patients.

Introduction: With the growth in Internet technology, online rating websites encourage patients to contribute actively in rating their physicians. These rating sites provide more information for patients, such as electronic word of mouth (eWOM) and physician trustworthiness. Although several studies in e-commerce have investigated the role of eWOM and seller trustworthiness in the consumer purchase decision-making process and the price premium for products or services, studies on the role of different information sources that reflect the service quality and delivery process in choosing a competent physician remain scarce. This research develops a two-equation model to examine the effect of different signals, i.e., patient-generated signals (PGSs) and system-generated signals (SGSs), on patient choice, which is an important predictor of physicians' economic returns., Methods: A secondary data econometric analysis and structural modeling using 2896 physicians' real data from a publicly available online physician rating site, i.e., Healthgrades.com, were conducted using a mixed-methods approach. A hybrid text mining approach was adopted to calculate the sentiment of each review., Results: We find that both PGSs and SGSs have a significant impact on patient choice at different stages of health consultation. Furthermore, disease risk negatively moderates the association between PGSs and information search, while the impact of both signals on patient willingness to pay a price premium is positively moderated by the disease risk., Conclusion: Our study contributes to the unified framework of signaling theory and Maslow's hierarchy of needs theory by making a clear distinction between PGSs or SGSs and their influence on patient decision-making across different disease risks. Moreover, PGSs and SGSs are two essential factors for physicians to increase their income., (Copyright © 2019 Elsevier Inc. All rights reserved.)

Objectives: This study sought to investigate the relationship between malnutrition and adverse cardiovascular (CV) events in heart failure with preserved ejection fraction (HFpEF)., Background: Malnutrition is associated with poor prognosis in a wide range of illnesses, however, the prognostic impact of malnutrition in HFpEF patients is not well known., Methods: Baseline malnutrition risk was determined in 1,677 patients with HFpEF enrolled in the Americas regions of the TOPCAT (Aldosterone Antagonist Therapy for Adults With Heart Failure and Preserved Systolic Function) trial, according to 3 categories of the geriatric nutritional risk index (GNRI) as previously validated: moderate to severe, GNRI of <92; low, GNRI of 92 to <98; and absence of risk, GNRI of ≥98. The relationships between malnutrition risk and the primary composite outcome of CV events (CV death, heart failure hospitalization, or resuscitated sudden death) and all-cause death were examined., Results: Approximately one-third of patients were at risk for malnutrition (moderate to severe: 11%; low: 25%; and absence of risk: 64%). Over a median of 2.9-years' follow-up, compared to those with absent risk for malnutrition, moderate to severe risk was associated with significantly increased risk for the primary outcome, CV death and all-cause death (hazard ratio [HR]: 1.34; 95% confidence interval [CI]: 1.02 to 1.76; HR: 2.06; 95% CI: 1.40 to 3.03; and HR: 1.79; 95% CI: 1.33 to 2.42, respectively) after multivariate adjustment for age, sex, history of CV diseases, and laboratory biomarkers., Conclusions: Patients with HFpEF are at an elevated risk for malnutrition, which was associated with an increased risk for CV events in this population., (Copyright © 2019 American College of Cardiology Foundation.

Objective: To derive and validate a model to predict a patient's probability of skilled nursing facility (SNF) discharge using data available from day 1 of hospitalization., Design: Using a retrospective cohort of 11,380 hospitalized patients, we obtained administrative and electronic medical data to identify predictors of SNF discharge., Setting and Participants: Single, urban academic medical center. Patients older than 50 years admitted to the medical service from July 2014 to August 2015., Methods: Primary outcome defined as SNF discharge. We split the cohort into derivation and validation sets (80/20). We created 1000 bootstrapped samples of the derivation set and used backward selection logistic regression on each bootstrapped sample. The final model included variables selected in ≥60% of the samples. To create a point-based index, a point value was assigned to each predictor variable relative to the logistic regression coefficient. The model's discrimination, calibration, positive predictive value, and negative predictive value tested in the validation set., Results: The overall frequency of SNF discharge was 12%. The final model included 11 variables. Significant demographic variables included age, marital status, insurance type, living alone, residence, and distance from hospital. The final model included 2 significant functional variables (mobility, bathing) and 3 significant clinical variables (admission mode, admission diagnosis, admission day of week). Impairment in mobility [odds ratio (OR) 1.8, 95% confidence interval (CI) 1.4-2.2] and impairment in bathing (OR 1.9, 95% CI 1.6-2.4) were both significant predictors of SNF discharge. The final model discriminated well in the validation cohort (c-statistic = 0.82) and was well calibrated., Conclusions/implications: It is possible to predict the day of admission with good accuracy and clinical usability a patient's risk of SNF discharge. The ability to identify early in the hospitalization patients likely to use post-acute services has implications for clinicians, administrators, and policy makers working to improve discharge planning and care transitions., (Copyright © 2019 AMDA – The Society for Post-Acute and Long-Term Care Medicine.

Objectives: This study sought to discern which central (e.g., heart rate, stroke volume [SV], filling pressure) and peripheral factors (e.g., oxygen use by skeletal muscle, body mass index [BMI]) during exercise were most strongly associated with the presence of heart failure and preserved ejection fraction (HFpEF) as compared with healthy control subjects exercising at the same workload., Background: The underlying mechanisms limiting exercise capacity in patients with HFpEF are not fully understood., Methods: In patients with HFpEF (n = 108), the hemodynamic response at peak exercise was measured using right-sided heart catheterization and was compared with that in healthy control subjects (n = 42) at matched workloads to reveal hemodynamic differences that were not attributable to the workload performed. The patients studied were prospectively included in the REDUCE-LAP HF (Reduce Elevated Left Atrial Pressure in Patients With Heart Failure) trials and HemReX (Effect of Age on the Hemodynamic Response During Rest and Exercise in Healthy Humans) study. Univariable and multivariable logistic regression models were used to analyze variables associated with HFpEF versus control subjects., Results: Compared with healthy control subjects, pulmonary capillary wedge pressure (PCWP) and SV were the only independent hemodynamic variables that were associated with HFpEF, a finding explaining 66% (p < 0.0001) of the difference between the groups. When relevant baseline characteristics were added to the base model, only BMI emerged as an additional independent variable, in total explaining of 90% of the differences between groups (p < 0.0001): PCWP (47%), BMI (31%), and SV (12%)., Conclusions: The study identified 3 key variables (PCWP, BMI, and SV) that independently correlate with the presence of patients with HFpEF compared with healthy control subjects exercising at the same workload. Therapies that decrease left-sided heart filling pressures could improve exercise capacity and possibly prognosis., (Copyright © 2019 American College of Cardiology Foundation.

Objectives: This study investigated the association between baseline renal function and the net benefit of spironolactone in patients with heart failure (HF) with a preserved ejection fraction (HFpEF)., Background: Guidelines recommend consideration of spironolactone to reduce HF hospitalization in HFpEF. However, spironolactone may increase risk for hyperkalemia and worsening renal function, particularly in patients with chronic kidney disease., Methods: This investigation analyzed data from patients enrolled in the TOPCAT (Treatment of Preserved Cardiac Function Heart Failure With an Aldosterone Antagonist Trial) Americas study (N = 1,767) to examine the association between the baseline estimated glomerular filtration rate (eGFR) and the primary composite outcome of cardiovascular death, HF hospitalization, or aborted cardiac arrest, as well as safety outcomes, including hyperkalemia, worsening renal function, and permanent drug discontinuation for adverse events (AEs). Variations in the efficacy and safety of spironolactone according to eGFR were examined in Cox models using interaction terms., Results: The incidence of both the primary outcome and drug-related AEs increased with declining eGFR. Compared with placebo, across all eGFR categories, spironolactone was associated with lower relative risk for the primary efficacy outcome and for hypokalemia, but higher relative risk for hyperkalemia, worsening renal function, and drug discontinuation. During 4-year follow-up, the absolute risk for AEs that prompted drug discontinuation was amplified in the lower eGFR categories, which suggested heightened risk for drug intolerance with declining renal function., Conclusions: Although consistent efficacy of spironolactone was observed across the range of eGFR, the risk of AEs was amplified in the lower eGFR categories. These data supported use of spironolactone to treat HFpEF patients with advanced chronic kidney disease only when close laboratory surveillance is possible., (Copyright © 2019 American College of Cardiology Foundation.

Background: Indices of cardiac mechanics are sensitive markers of subclinical myocardial dysfunction. Improved understanding of the clinical correlates and heritability of cardiac mechanics could result in novel insight into the acquired and genetic risk factors for myocardial dysfunction. Therefore, we sought to determine the clinical correlates and heritability of indices of cardiac mechanics in whites and African Americans (AAs)., Methods: We examined 2058 participants stratified by race (1104 whites, 954 AA) in the Hypertension Genetic Epidemiology Network (HyperGEN), a population- and family-based study, and performed digitization of analog echocardiograms with subsequent speckle-tracking analysis. We used linear mixed effects models to determine the clinical correlates of indices of cardiac mechanics (longitudinal, circumferential, radial strain; early diastolic strain rate; and early diastolic tissue velocities). Heritability estimates for cardiac mechanics were calculated using maximum-likelihood variance component analyses in Sequential Oligogenic Linkage Analysis Routine (SOLAR), with adjustment for clinical and echocardiographic covariates., Results: Several clinical characteristics and conventional echocardiographic parameters were found to be associated with speckle-tracking traits of cardiac mechanics. Male sex, blood pressure, and fasting glucose were associated with worse longitudinal strain (LS) (P < 0.05 for all) after multivariable adjustment. After adjustment for covariates, LS, e' velocity, and early diastolic strain rate were found to be heritable; LS and e' velocity had higher heritability estimates in AAs compared to whites., Conclusions: Indices of cardiac mechanics are heritable traits even after adjustment for clinical and conventional echocardiographic correlates. These findings provide the basis for future studies of genetic determinants of these traits that may elucidate race-based differences in heart failure development., (Copyright © 2018 Elsevier B.V.

Objectives: This study sought to characterize the course of decongestion among patients hospitalized for acute heart failure (AHF) by history of atrial fibrillation (AF) and/or atrial flutter (AFL)., Background: AF/AFL and chronic heart failure (HF) commonly coexist. Little is known regarding the impact of AF/AFL on relief of congestion among patients who develop AHF., Methods: We pooled patients from 3 randomized trials of AHF conducted within the Heart Failure Network, the DOSE (Diuretic Optimization Strategies) trial, the ROSE (Renal Optimization Strategies) trial, and the CARRESS-HF (Cardiorenal Rescue Study in Acute Decompensated Heart Failure) trial. The association between history of AF/AFL and in-hospital changes in various metrics of congestion was assessed using covariate-adjusted linear and ordinal logistic regression models., Results: Of 750 unique patients, 418 (56%) had a history of AF/AFL. Left ventricular ejection fraction was higher (35% vs. 27%, respectively; p < 0.001), and N-terminal pro-brain natriuretic peptide (NT-proBNP) levels were nonsignificantly lower at baseline (4,210 pg/ml vs. 5,037 pg/ml, respectively; p = 0.27) in patients with AF/AFL. After adjustment of covariates, history of AF/AFL was associated with less substantial loss of weight (-5.7% vs. -6.5%, respectively; p = 0.02) and decrease in NT-proBNP levels (-18.7% vs. -31.3%, respectively; p = 0.003) by 72 or 96 h. History of AF/AFL was also associated with a blunted increase in global sense of well being at 72 or 96 h (p = 0.04). There was no association between history of AF/AFL and change in orthodema congestion score (p = 0.67) or 60-day composite clinical endpoint (all-cause mortality or any rehospitalization; hazard ratio: 1.21; 95% confidence interval: 0.92 to 1.59; p = 0.17)., Conclusions: More than half of the patients admitted with AHF had a history of AF/AFL. History of AF/AFL was independently associated with a blunted course of in-hospital decongestion. Further research is required to understand the utility of specific therapies targeting AF/AFL during hospitalization for AHF., (Copyright © 2019 American College of Cardiology Foundation.

Objectives: This study assessed the relationship between atrial fibrillation (AF) and outcomes in the TOPCAT (Treatment of Preserved Cardiac Function Heart Failure With an Aldosterone Antagonist) trial, to evaluate whether AF modified the treatment response to spironolactone and whether spironolactone influenced post-randomization AF., Background: AF is common in heart failure with preserved ejection fraction (HFpEF) and likely contributes to increased risk of adverse outcomes., Methods: A total 1,765 patients enrolled in TOPCAT trial in North and South America were divided into 3 groups: no known AF, history of AF without AF at enrollment, and AF found on the electrocardiogram (ECG) at enrollment. We assessed outcomes and treatment response to spironolactone in all groups, and the association between post-randomization AF and outcomes in patients free of AF at baseline. The primary outcome of the TOPCAT trial was a composite of cardiovascular mortality, aborted cardiac arrest, or heart failure hospitalization., Results: A total of 760 patients (43%) had a history of AF (18%) or AF on ECG at enrollment (25%). The highest adjusted risk was associated with AF at enrollment (primary outcome, hazard ratio: 1.34; 95% confidence interval: 1.09 to 1.65; p = 0.006; and an increased early risk of secondary outcomes). Neither history of AF nor AF at enrollment modified the beneficial treatment effect of spironolactone. Post-randomization AF, which occurred in 6.3% of patients, was not influenced by spironolactone treatment, but was associated with an increased early risk of the primary outcome (hazard ratio: 2.32; 95% confidence interval: 1.59 to 3.40; p < 0.0001) and secondary outcomes., Conclusions: AF at enrollment was associated with increased cardiovascular risk in HFpEF patients in the TOPCAT study. Post-randomization AF, which was associated with an increased risk of morbidity and mortality, was not influenced by spironolactone.
