Background Out-of-pocket (OOP) drug costs for Medicare Fee-for-Service (FFS) beneficiaries with heart failure with reduced ejection fraction (HFrEF) are not well characterized. This study evaluated Part D OOP spending by Medicare beneficiaries with chronic HFrEF, stratified by those with and without a worsening HF event (WHFE). Methods Medicare FFS 100% Part D claims were used to identify HFrEF patients with 12 months of continuous Part D enrollment in 2018. HFrEF was defined as 1 inpatient or 2 outpatient claims of systolic HF or 1 systolic HF plus 1 HF outpatient claim. WHFE was defined as having a HF hospitalization or intravenous diuretic use within 12 months of HFrEF index date. OOP costs by Medicare Part D coverage phase for all covered drugs were calculated for HFrEF patients, and those with and without WHFE. Results Of 305,373 Medicare patients with HFrEF, 26% had a WHFE. Total mean (SD) OOP drug costs among all HFrEF patients was $1,166 (1,205)/year. Patients with WHFE and patients without WHFE had respectively a mean (SD) annual OOP costs of $1,302 (1,273) and $1,117 (1,176). Over 39% of HFrEF patients entered the "donut hole" (44% and 37% of patients with WHFE and without WHFE, respectively), while 11% of HFrEF patients entered the catastrophic phase (13% and 10% of patients with and without WHFE, respectively). Conclusion More than 1 in 10 patients with heart failure entered the catastrophic phase within Medicare-Fee-For-Service, whereas in 2018 only 10% of costs were attributable to heart failure medication and 90% to comorbidities.

BACKGROUND: We aimed to investigate the associations of glycemic markers (hemoglobin A(1C) [HbA(1C)], fasting plasma glucose [FPG] and glycemic status [normoglycemia, prediabetes and diabetes]) with incident heart failure (HF) and its subtypes, among Blacks. METHODS: We included 2,290 community-dwelling Blacks(64% women, mean age 58 years) without prevalent HF from the Jackson Heart Study who attended the second exam (2005–2008). The associations between glycemic markers and incident HF (and subtypes including HF with preserved ejection fraction [HFpEF] and reduced ejection fraction [HFrEF]) were evaluated using Cox proportional hazards regression models, adjusting for risk factors and coronary heart disease. RESULTS: There were 119 incident HF events (48 HFpEF, 58 HFrEF, and 13 unclassified HF events) over a median follow-up of 10.5 years. Higher levels of HbA(1C) (HR per SD increment, 1.30; 95% CI 1.12, 1.51) and FPG (HR per SD increment FPG: 1.32; 95% CI: 1.17, 1.48) were associated with a higher risk of incident HF. Compared to normal glycemia, diabetes status was associated with a higher risk of incident HF (HR: 1.24; 95%CI: 1.02, 2.05). HbA(1C) was significantly associated with higher risks of HFpEF (HR per SD increment: 1.41, 95% CI: 1.18, 1.69) and HFrEF (HR per SD increment: 1.32; 95% CI: 1.12, 1.56). FPG was significantly associated with higher risk of HFpEF (HR per SD increment: 1.35, 95% CI: 1.14, 1.62) but not HFrEF (HR per SD increment: 1.12; 95% CI: 0.53, 2.35). CONCLUSIONS: Among community-dwelling Blacks, higher levels of glycemic markers were associated with higher risk of HF subtypes. CLINICAL TRIALS.

INTRODUCTION: Black patients have a higher incidence of heart failure (HF) and worse outcomes than white patients. Guidelines recommend palliative care for patients with advanced HF, but no studies have examined outcomes in a black patient cohort. METHODS: This is a post hoc analysis of the Palliative Care in Heart Failure trial, which randomized patients to usual care plus a palliative care intervention (UC+PAL) or usual care (UC). Quality of life (QoL) was measured using Kansas City Cardiomyopathy Questionnaire (KCCQ) and Functional Assessment of Chronic Illness Therapy-Palliative Care scale (FACIT-Pal). RESULTS: Black patients represented 41% of the 148 patients. At six months, QoL improved more in UC+PAL than UC for both racial subgroups. The difference was greater for black than white patients (difference: KCCQ 10.8 vs. 2.5; FACIT-Pal: 14.8 vs. 3.9). However, the findings were not statistically significant. CONCLUSIONS: Larger studies are needed to assess the benefits of palliative care for black patients with HF. ClinicalTrials.gov Identifier: NCT01589601.

Objective To evaluate the relationship between hypertensive diseases in pregnancy and kidney function later in life. Methods We evaluated measured glomerular filtration rate (mGFR) using iothalamate urinary clearance in 725 women of the Genetic Epidemiology Network of Arteriopathy (GENOA) study. Women were classified by self-report as nulliparous (n=62), a history of normotensive pregnancies (n=544), a history of hypertensive pregnancies (n=102), or a history of pre-eclampsia (n=17). We compared adjusted associations among these four groups with mGFR using generalized estimating equations to account for familial clustering. Chronic kidney disease (CKD) was defined as mGFR of less than 60 mL/min per 1.73 m2 or urinary albumin-creatinine ratio (UACR) greater than or equal to 30 mg/g. Results Among women with kidney function measurements (mean age, 59±9 years, 52.9% African American), those with a history of hypertensive pregnancy had lower mGFR (–4.66 ml/min per 1.73 m2; 95% CI, -9.12 to -0.20) compared with women with a history of normotensive pregnancies. Compared with women with a history of normotensive pregnancies, women with a history of hypertensive pregnancy also had higher odds of mGFR less than 60 ml/min per 1.73 m2 (odds ratio, 2.09; 95% CI, 1.21 to 3.60). Additionally, women with a history of hypertensive pregnancy had greater odds for chronic kidney disease (odds ratio, 4.89; 95% CI, 1.55 to 15.44), after adjusting for age, race, education, smoking history, hypertension, body mass index, and diabetes. Conclusion A history of hypertension in pregnancy is an important prognostic risk factor for kidney disease. To our knowledge, this is the first and largest investigation showing the association between hypertensive diseases in pregnancy and subsequent kidney disease using mGFR in a large biracial cohort.

The authors sought to investigate associations between sacubitril/valsartan adherence and clinical outcomes after hospitalization for heart failure with reduced ejection fraction (HFrEF).Sacubitril/valsartan improves outcomes in HFrEF, though the extent to which medication adherence is associated with outcomes in routine care is less well characterized.The authors analyzed patients aged ≥65 years hospitalized for HFrEF within the Get With the Guidelines-Heart Failure registry linked with Medicare claims between October 2015 and September 2018 who were discharged with sacubitril/valsartan. Sacubitril/valsartan adherence was assessed using medication fills to calculate proportion of days covered (PDC) through 90 days postdischarge. Associations between postdischarge adherence (PDC or ≥80%) and risk of readmission and death within 1 year were examined by comparing cumulative incidences and adjusted event rates.Among 897 patients prescribed sacubitril/valsartan at discharge, 295 (32.9%) had PDC ≥80% and 602 (67.1%) had PDC 80%. Baseline characteristics were balanced between groups. Compared with patients with PDC 80%, patients with PDC ≥80% had a significantly lower adjusted hazard of all-cause rehospitalization (HR: 0.66 [95% CI: 0.48-0.89]) and death (HR: 0.42 [95% CI: 0.22-0.79]) at 90 days and at 1 year (HR: 0.69 [95% CI: 0.56-0.86] and HR: 0.53 [95% CI: 0.38-0.74], respectively). For every 5 percentage point increase in PDC, patients experienced a significant reduction in rehospitalization (HR: 0.98 [95% CI: 0.97-0.99]) and death (HR: 0.96 [95% CI: 0.94-0.97]) at 1 year.In patients hospitalized for HFrEF and discharged on sacubitril/valsartan, high adherence to sacubitril/valsartan within 90 days after discharge was associated with substantially lower rates of readmission and death. Additional efforts to improve adherence with sacubitril/valsartan and other guideline-directed medical therapies in HFrEF are warranted.

BACKGROUND AND AIMS: Polyvascular disease is an independent predictor of major adverse cardiovascular events (MACE). The relationship between the number of diseased arterial beds and MACE is unknown. How MACE risk changes in individuals with type 2 diabetes (T2D) is also understudied. Furthermore, it is unknown whether heart failure (HF) status and hemoglobin A1c (HbA1c) levels influence outcomes in polyvascular disease. This analysis from the Exenatide Study of Cardiovascular Event Lowering trial (EXSCEL) aimed to examine the risk associated with increasing number of diseased arterial beds on MACE and all-cause mortality (ACM). METHODS: Cox models were used to test associations between the number of diseased arterial beds and MACE and ACM. Prespecified interaction testing between number of diseased arterial beds with baseline HF, HbA1c (≤8% vs. >8%), and treatment assignment was performed. RESULTS: Overall, 14,751 participants were included; 26.5% were without atherosclerosis, 58.9% had 1-bed, 12.3% had 2-bed, and 2.3% had 3-bed disease. An increasing burden of atherosclerotic disease was associated with increasing risk of MACE (adjusted HR [aHR] 1.71 [95% CI 1.46–2.02]; 2.61 [2.17–3.15]; 3.46 [2.69–4.45] for 1, 2, and 3 beds, respectively, p < 0.001 for all) and ACM (1.94 [1.56–2.42]; 3.03 [2.33–3.95]; 3.66 [2.59–5.18] for 1, 2, and 3 beds, respectively, p < 0.001 for all). Prespecified interaction testing did not reveal any significant associations. CONCLUSIONS: In patients with T2D, compared to those without atherosclerotic vascular disease, risk of MACE and ACM increases incrementally with each additional diseased arterial bed.

In the VerICiguaT Global Study in Subjects with Heart Failure with Reduced Ejection Fraction (VICTORIA) trial, vericiguat reduced the risk of mortality due to cardiovascular problems and of hospitalization due to heart failure (HF) among patients with HF with reduced ejection fraction (HFrEF) and recent worsening HF events (WHFEs). The representativeness of the VICTORIA population of patients with WHFE in clinical practice is unknown.Patients with HF and ejection fraction45% were identified in the Practice Innovation And Clinical Excellence (PINNACLE) registry and were stratified by the occurrence of WHFEs. Characteristics and outcomes of patients in the PINNACLE registry with and without WHFEs were compared to the VICTORIA population. Of the 14,180 PINNACLE patients identified with HFrEF, 26.5% had had a WHFE. The VICTORIA population was similar to PINNACLE patients with WHFEs in mean age (67.3 vs 66.7), ejection fraction (28.9% vs 28.3%), body mass index (26.8 vs 27.6), and comorbidity burden. The rate of hospitalization because of HF at 1 year was 29.6% in the placebo group of VICTORIA, compared to 35.8% in PINNACLE patients with WHFEs and 13.3% in patients without WHFEs.The PINNACLE patients with WHFEs meeting the VICTORIA definition resembled the VICTORIA population in characteristics and outcomes, suggesting that VICTORIA's population may be generalizable to patients with WHFEs in clinical practice.

Sodium-glucose cotransporter-2 inhibitor therapy is well suited for initiation during the heart failure hospitalization, owing to clinical benefits that accrue rapidly within days to weeks, a strong safety and tolerability profile, minimal to no effects on blood pressure, and no excess risk of adverse kidney events. There is no evidence to suggest that deferring initiation to the outpatient setting accomplishes anything beneficial. Instead, there is compelling evidence that deferring in-hospital initiation exposes patients to excess risk of early postdischarge clinical worsening and death. Lessons from other heart failure with reduced ejection fraction therapies highlight that deferring initiation of guideline-recommended medications to the U.S. outpatient setting carries a >75% chance they will not be initiated within the next year. Recognizing that 1 in 4 patients hospitalized for worsening heart failure die or are readmitted within 30 days, clinicians should embrace the in-hospital period as an optimal time to initiate sodium-glucose cotransporter-2 inhibitor therapy and treat this population with the urgency it deserves.

Background Greater variability in the estimated glomerular filtration rate (eGFR) is associated with higher mortality in patients with chronic kidney disease (CKD). Heart failure (HF) is common in CKD and may increase variability through changes in hemodynamic and volume regulation. We sought to determine if patients with vs without HF have higher kidney function variability in CKD, and to define the association with mortality. Methods and Results Patients undergoing coronary angiography from 2003 to 2013 with an eGFR of less than 60 mL/min/1.73 m2 were evaluated from the Duke Databank for Cardiovascular Disease. Variability in the eGFR, measured as the coefficient of variation (CV) of residuals from the regression of eGFR vs time, was calculated spanning 3 months to 2 years after catheterization. Mortality was assessed 2 to 7 years after catheterization. Patients were grouped into 3 HF phenotypes: HF with reduced ejection fraction, HF with preserved ejection, and no HF. Regression was used to evaluate associations between HF phenotypes and variability in the eGFR and between variability in the eGFR and mortality rate with stratification by HF phenotype. Among 3767 participants, the median eGFR at baseline was 45 mL/min/1.73 m2 (interquartile range 33-53 mL/min/1.73 m2), and longitudinal measures of eGFR over 21 months had within-patient residual variability (CV) of 14% (9%–20%). In adjusted analyses, variability in the eGFR was greater in those with HF with preserved ejection (n = 695, CV difference 0.98%, 95% confidence interval 0.14%–1.81%) or HF with reduced ejection fraction (n = 800, CV difference 2.51%, 95% confidence interval 1.66%–3.37%) relative to no HF (n = 2272). In 3068 participants eligible for mortality analysis, the presence of HF and greater variability in the eGFR were each associated independently with higher mortality, but there was no evidence of interaction between variability in the eGFR and any HF phenotype (all P for interaction ≥.49). Conclusions Variability in the eGFR is greater in patients with HF and associated with mortality. Prediction algorithms and classification schemes should consider not only static, but also dynamic eGFR variability in HF and CKD prognostication.

Substance use is common among those with heart failure (HF) and is associated with worse clinical outcomes. Alcohol, tobacco, cannabis, and cocaine are commonly abused substances that can contribute to the development and worsening of HF. Heavy alcohol consumption can lead to dilated cardiomyopathy, whereas moderate intake may decrease incident HF. Tobacco increases the risk of HF through coronary artery disease and coronary artery disease–independent mechanisms. Continued smoking worsens outcomes for those with HF and cessation is associated with an improved risk of major adverse cardiac events. Cannabis has complex interactions on the cardiovascular system depending on the method of consumption, amount consumed, and content of cannabinoids. Delta-9-tetrahydrocannabinol can increase sympathetic tone, cause vascular dysfunction, and may increase the risk of myocardial infarction. Cannabidiol is cardioprotective in preclinical studies and is a potential therapeutic target. Cocaine increases sympathetic tone and is a potent proarrhythmogenic agent. It increases the risk of myocardial infarction and can also lead to a dilated cardiomyopathy. The use of beta-blockers in those with HF and cocaine use is likely safe and effective. Future studies are needed to further elucidate the impact of these substances both on the development of HF and their effects on those who have HF.

Background: Prior studies suggest similar long-term mortality rates for patients with heart failure (HF) with preserved ejection fraction (HFpEF) vs reduced ejection fraction. However, although coronary heart disease (CHD) is associated with worse prognosis in HF, clinical outcomes are less well characterized for HF without CHD. We investigated the characteristics and 5-year mortality outcomes among patients with HF without significant CHD, stratified by EF. Methods: Patients with clinical heart failure who underwent coronary angiography at Duke University Medical Center from 1996 through 2009 and had no significant CHD with EF ≤ 40% were compared with patients without significant CHD with EF > 40%. Survival was examined using Kaplan-Meier methods and multivariable Cox proportional hazards modeling. Analyses were repeated using EF ≥ 50%. Results: Of 3154 patients with HF without significant CHD, 1530 (48.5%) had HFpEF (EF > 40%). These patients were older and more likely to have a Charlson Index ≥ 2 than patients with reduced EF. Patients with HFpEF had a lower risk of death than those with reduced EF (unadjusted hazard ratio [HR] 0.85; 95% confidence interval [CI] 0.74-0.99). From 1996 through 2009, the secular trend of death decreased among patients without CHD and with reduced EF (HR 0.92; 95% CI 0.88-0.97) but not among those with preserved EF (HR 0.99; 95% CI 0.93-1.05; P interaction 0.095). No finding was significant after multivariable risk adjustment. Results were consistent when defining preserved EF as EF ≥ 50%. Conclusions: Among patients without significant CHD, those with HFpEF had similar risks of 5-year mortality as patients with HF with reduced ejection fraction. Résumé: Introduction: Des études antérieures indiquent des taux de mortalité à long terme similaires entre les patients atteints d’insuffisance cardiaque (IC) avec fraction d’éjection (FE) préservée (ICFEP) vs les patients atteints d’IC avec FE réduite (ICFER). Toutefois, bien que la coronaropathie soit associée à un plus mauvais pronostic de l’IC, les résultats cliniques sont moins bien définis que ceux de l’IC sans coronaropathie. Nous avons examiné les caractéristiques et les résultats des patients atteints d’IC sans coronaropathie importante, stratifiés selon la FE, sur la mortalité dans les cinq ans. Méthodes: Nous avons comparé les patients montrant des signes cliniques d’IC qui avaient subi une angiographie coronarienne à la Duke University de 1996 à 2009 et n’avait pas de coronaropathie importante avec FE ≤ 40 % aux patients sans coronaropathie importante avec FE > 40 %. Nous avons examiné la survie à l’aide de la méthode de Kaplan-Meier et du modèle multivarié à risques proportionnels de Cox. Nous avons répété les analyses en fonction d’une FE ≥ 50 %. Résultats: Parmi les 3 154 patients atteints d’IC sans coronaropathie importante, 1 530 (48,5 %) avaient une ICFEP (FE > 40 %). Ces patients étaient plus âgés et plus susceptibles d’avoir un indice de Charlson ≥ 2 que les patients atteints d’ICFER. Les patients atteints d’ICFEP avaient un risque plus faible de mortalité que ceux atteints d’une ICFER (rapport de risque [RR] non ajusté 0,85; intervalle de confiance [IC] à 95 % 0,74-0,99). De 1996 à 2009, la tendance séculaire de la mortalité avait diminué chez les patients sans coronaropathie et qui avaient une FE réduite (RR 0,92; IC à 95 % 0,88-0,97), mais non chez ceux qui avaient une FE préservée (RR 0,99; IC à 95 % 0,93-1,05; valeur P de l’interaction 0,095). Aucun résultat n’était significatif après l’ajustement multivarié en fonction du risque. Les résultats étaient cohérents lorsque la FE préservée était définie par une FE ≥ 50 %. Conclusions: Chez les patients sans coronaropathie importante, ceux atteints d’une ICFEP avaient des risques similaires de mortalité dans les cinq ans aux patients atteints d’ICFER.

Background: The prediction of outcomes in patients with heart failure (HF) may inform prognosis, clinical decisions regarding treatment selection, and new trial planning. The VerICiguaT Global Study in Subjects With Heart Failure With Reduced Ejection Fraction included high-risk patients with HF with reduced ejection fraction and a recent worsening HF event. The study participants had a high event rate despite the use of contemporary guideline-based therapies. To provide generalizable predictive data for a broad population with a recent worsening HF event, we focused on risk prognostication in the placebo group.Methods and Results: Data from 2524 participants randomized to placebo with chronic HF (New York Heart Association functional class II–IV) and an ejection fraction of less than 45% were studied and backward variable selection was used to create Cox proportional hazards models for clinical end points, selecting from 66 candidate predictors. Final model results were produced, accounting for missing data, and nonlinearities. Optimism-corrected c-indices were calculated using 200 bootstrap samples. Over a median follow-up of 10.4 months, the primary outcome of HF hospitalization or cardiovascular death occurred in 972 patients (38.5%). Independent predictors of increased risk for the primary end point included HF characteristics (longer HF duration and worse New York Heart Association functional class), medical history (prior myocardial infarction), and laboratory values (higher N-terminal pro-hormone B-type natriuretic peptide, bilirubin, urate; lower chloride and albumin). Optimism-corrected c-indices were 0.68 for the HF hospitalization/cardiovascular death model, 0.68 for HF hospitalization/all-cause death, 0.72 for cardiovascular death, and 0.73 for all-cause death.Conclusions: Predictive models developed in a large diverse clinical trial with comprehensive clinical and laboratory baseline data—including novel measures—performed well in high-risk patients with HF who were receiving excellent guideline-based clinical care.Clinical Trial Registration: Clinicaltrials.gov identifier, NCT02861534.Lay Summary: Patients with heart failure may benefit from tools that help clinicians to better understand a patient's risk for future events like hospitalization. Relatively few risk models have been created after the worsening of heart failure in a contemporary cohort. We provide insights on the risk factors for clinical events from a recent, large, global trial of patients with worsening heart failure to help clinicians better understand and communicate prognosis and select treatment options.

Exercise intolerance (EI) is the primary manifestation of chronic heart failure with preserved ejection fraction (HFpEF), the most common form of heart failure among older individuals. The recent recognition that HFpEF is likely a systemic, multiorgan disorder that shares characteristics with other common, difficult-to-treat, aging-related disorders suggests that novel insights may be gained from combining knowledge and concepts from aging and cardiovascular disease disciplines. This state-of-the-art review is based on the outcomes of a National Institute of Aging-sponsored working group meeting on aging and EI in HFpEF. We discuss aging-related and extracardiac contributors to EI in HFpEF and provide the rationale for a transdisciplinary, "gero-centric" approach to advance our understanding of EI in HFpEF and identify promising new therapeutic targets. We also provide a framework for prioritizing future research, including developing a uniform, comprehensive approach to phenotypic characterization of HFpEF, elucidating key geroscience targets for treatment, and conducting proof-of-concept trials to modify these targets.

Decongestion is a primary goal during hospitalizations for decompensated heart failure (HF). However, data surrounding the preferred route and strategy of diuretic administration are limited with varying results in prior studies.This is a retrospective analysis using patients from ASCEND-HF with a stable diuretic strategy in the first 24 hours following randomization. Patients were divided into three groups: intravenous (IV) continuous, IV bolus and oral strategy. Baseline characteristics, in-hospital outcomes, 30-day composite cardiovascular mortality or HF rehospitalization and 180-day all-cause mortality were compared across groups. Inverse propensity weighted modeling was used for adjustment.Among 5,738 patients with a stable diuretic regimen in the first 24 hours (80% of overall ASCEND trial), 3,944 (68.7%) patients received IV intermittent bolus administration of diuretics, 799 (13.9%) patients received IV continuous therapy and 995 (17.3%) patients with oral administration. Patients in the IV continuous group had a higher baseline creatinine (IV continuous 1.4 [1.1-1.7]; intermittent bolus 1.2 [1.0-1.6]; oral 1.2 [1.0-1.4] mg/dL; P0.001) and high NTproBNP (IV continuous 5,216 [2,599-11,603]; intermittent bolus 4,944 [2,339-9,970]; oral 3,344 [1,570-7,077] pg/mL; P0.001). There was no difference between IV continuous and intermittent bolus group in weight change, total urine output and change in renal function till 10 days/discharge (adjusted P0.05 for all). There was no difference in 30 day mortality and HF readmission (adjusted OR 1.08 [95%CI: 0.74, 1.57]; P = 0.701) and 180 days mortality (adjusted OR 1.04 [95%CI: 0.75, 1.43]; P = 0.832).In a large cohort of patients with decompensated HF, there were no significant differences in diuretic-related in-hospital, or post-discharge outcomes between IV continuous and intermittent bolus administration. Tailoring appropriate diuretic strategy to different states of acute HF and congestion phenotypes needs to be further investigated.

Aims Associations between growth differentiation factor‐15 (GDF‐15), cardiovascular outcomes, and exercise capacity among patients with a recent hospitalization for heart failure (HHF) and heart failure with reduced ejection fraction (HFrEF) are unknown. We utilized data from the ‘Functional Impact of GLP‐1 for Heart Failure Treatment’ (FIGHT) study to address these knowledge gaps. Methods and results FIGHT was a randomized clinical trial testing the effect of liraglutide (vs. placebo) among 300 participants with HFrEF and a recent HHF. Multivariable regression models evaluated associations between baseline GDF‐15 and change in GDF‐15 (per 1000 pg/mL increase from baseline to 30 days) with clinical outcomes (at 180 days) and declines in exercise capacity (6 min walk distance ≥ 45 m). At baseline (n = 249), median GDF‐15 value was 3221 pg/mL (interquartile range 1938–5511 pg/mL). Participants in the highest tertile of baseline GDF‐15 were more likely to be male and have more co‐morbidities. After adjustment, an increase in GDF‐15 over 30 days was associated with higher risk of death or HHF [hazard ratio 1.35, 95% confidence interval (CI) 1.11–1.64]. In addition, higher baseline GDF‐15 (per 1000 pg/mL until 6000 pg/mL) and an increase in GDF‐15 over 30 days were associated with declining 6 min walk distance (odds ratio 1.26, 95% CI 1.02–1.55 and odds ratio 1.37, 95% CI 1.12–1.69, respectively). GDF‐15 levels remained stable among participants randomized to liraglutide. Conclusions An increase in GDF‐15 over 30 days among patients in HFrEF was independently associated with an increased risk of cardiovascular events and declining exercise capacity. These results support the value of longitudinal GDF‐15 trajectory in informing risk of heart failure disease progression.

Background: \ud Elevated plasma interleukin-6 (IL-6) concentrations are frequently observed in patients with acute heart failure (AHF). However, the predictive value of serial IL-6 measurements beyond brain natriuretic peptide (BNP) remains poorly characterized.\ud \ud Methods and Results: \ud This was a retrospective analysis of the PROTECT cohort (2033 patients with AHF). Plasma IL-6 and BNP levels were determined on days 1, 2, 7 and 14 after admission for AHF in 1591 (78.3%), 1462 (71.9%), 1445 (71.1%) and 1451 (71.4%) patients, respectively. The primary endpoint was 180-day all-cause mortality. The median day-1 IL-6 concentration was 11.1 pg/mL (IQR: 6.6, 20.9) and decreased to 10.1 pg/mL (IQR: 5.6-18.5) at day-7. Higher cross-sectional IL-6 concentrations at all time-points predicted the primary endpoint, independent of a risk model for this cohort and changes in BNP. Each doubling of IL-6 between day-1 and day-7 predicted the primary endpoint independent of baseline IL-6 concentrations, the risk model, baseline BNP and changes in BNP [HR (95% CI): 1.18 (1.07-1.30), p=0.0013]. Collectively, 214 (17%) patients experienced at least a doubling of their IL-6 concentrations between day-1 and day-7.\ud \ud Conclusions: \ud We demonstrate that the temporal evolution patterns of IL-6 in patients with AHF have additive prognostic value independent of changes in BNP.

Randomized clinical trials are the foundation of evidence-based medicine and central to practice guidelines and patient care decisions. Nonetheless, randomized trials in heart failure (HF) populations have become increasingly difficult to conduct and are frequently associated with slow patient enrollment, highly selected populations, extensive data collection, and high costs. The traditional model for HF trials has become particularly difficult to execute in the United States, where challenges to site-based research have frequently led to modest U.S. representation in global trials. In this context, the TRANSFORM-HF (Torsemide Comparison with Furosemide for Management of Heart Failure) trial aims to overcome traditional trial challenges and compare the effects of torsemide versus furosemide among patients with HF in the United States. Loop diuretic agents are regularly used by most patients with HF and practice guidelines recommend optimal use of diuretic agents as key to a successful treatment strategy. Long-time clinical experience has contributed to dominant use of furosemide for loop diuretic therapy, although preclinical and small clinical studies suggest potential advantages of torsemide. However, due to the lack of appropriately powered clinical outcome studies, there is insufficient evidence to conclude that torsemide should be routinely recommended over furosemide. Given this gap in knowledge and the fundamental role of loop diuretic agents in HF care, the TRANSFORM-HF trial was designed as a prospective, randomized, event-driven, pragmatic, comparative-effectiveness study to definitively compare the effect of a treatment strategy of torsemide versus furosemide on long-term mortality, hospitalization, and patient-reported outcomes among patients with HF.

Background We assessed the prevalence and clinical characteristics of patients with acute decompensated heart failure (ADHF) who live alone and how they were different from patients who lived with someone else. Methods We analyzed patients in the REHAB-HF Trial. Patients were ≥60 years with preserved or reduced ejection fraction who were hospitalized with ADHF. Results Of 202 patients, 67 (33.2%) lived alone. Patients who lived alone had a mean age of 72.4±7.8 years, 64% (n=43) of whom were female, 52% (n=35) were non-white and had a mean 6.1±5.5 comorbidities. Patients living alone were largely similar in baseline characteristics, comorbid burden and prescribed medications to patients living with someone else. However, patients living alone were more likely to be female than patients living with someone else (63% [n=43] vs. 49% [n=66], p=0.04). Patients living alone had severe impairments in physical function and QoL. Cognitive dysfunction was present in 81% of those living alone. However, after adjusting for sex, no differences in physical function, depression, cognitive dysfunction or QoL were noted between patients who lived alone or those who lived with someone else. Conclusions In this diverse population of older ADHF patients, 33% lived alone (versus 26% in the general population). Those living alone were more often female, non-white, and had >6 comorbidities. Treatment strategies for older ADHF patients should consider the potential impact of social determinants.

Multiple newer medications benefit patients with heart failure with reduced ejection fraction (HFrEF). While these therapies benefit the broad population with HFrEF, the efficacy and safety of these therapies have been less well characterized in patients with significant comorbidities. Common comorbidities of high interest in heart failure (HF) include diabetes mellitus, chronic kidney disease (CKD), atrial fibrillation, and obesity, and each has potential implications for clinical management. As the burden of comorbidities increases in HF populations, risk-benefit assessments of HF therapies in the context of different comorbidities are increasingly relevant for clinical practice. This review summarizes data regarding the core HFrEF therapies in the context of comorbidities, with specific attention to sodium-glucose cotransporter 2 inhibitors, sacubitril/valsartan, mineralocorticoid receptor antagonists (MRAs), and beta-blockers. In general, studies support consistent treatment effects with regard to clinical outcome benefits in the presence of comorbidities. Likewise, safety profiles are relatively consistent irrespective of comorbidities, with the exception of heightened risk of hyperkalemia with MRA therapy in patients with severe CKD. In conclusion, while HF management is complex in the context of multiple comorbidities, the totality of evidence strongly supports guideline-directed medical therapies as foundational for improving outcomes in these high-risk patients.

Background: Hospitalization for heart failure (HF) is associated with increased risk of death among patients with chronic HF. The degree to which hospitalization for HF is a distinct biologic entity with independent prognostic value versus a marker of higher risk chronic HF patients is unclear. Methods: After excluding patients with new-onset HF, the ASCEND-HF trial (Acute Study of Clinical Effectiveness of Nesiritide in Decompensated Heart Failure) included 4205 patients hospitalized for worsening chronic HF with reduced or preserved ejection fraction. The present analysis compared patients by presence or absence of prior HF hospitalization within 12 months and by timing of prior HF hospitalization relative to index hospitalization. Associations with 180-day all-cause mortality were assessed, including adjustment for 27 prespecified clinical factors. Results: Overall, 2241 (53.3%) patients had a HF hospitalization within the prior 12 months and 1964 (46.7%) did not. Mortality rates at 180 days were 15.5% and 11.9%, respectively. In unadjusted analyses, prior HF hospitalization was associated with increased risk of 180-day mortality (HR, 1.35 [95% CI, 1.14–1.59]; P P =0.064). Similarly, after adjustment, compared with patients without prior hospitalization, prior HF hospitalization was not associated with mortality, irrespective of timing (0–4 months: HR, 1.10 [95% CI, 0.87–1.39], P =0.41; 4–8 months: HR, 0.95 [95% CI, 0.70–1.27]; P =0.72; 8–12 months: HR, 1.06 [95% CI, 0.74–1.51], P =0.77; >12 months: HR, 0.81 [95% CI, 0.63–1.06], P =0.12). Conclusions: In this cohort of patients hospitalized for worsening HF, prior HF hospitalization was not associated with 180-day mortality after comprehensively accounting for patient characteristics measured during the index patient visit. Clinical confounders measured at the point-of-care may explain previously observed associations between prior HF hospitalization and mortality, and these clinical factors may be a more direct means of predicting patient survival.

OBJECTIVES: The authors estimated changes of stressed blood volume (SBV) induced by splanchnic nerve block (SNB) in patients with either decompensated or ambulatory heart failure with reduced ejection fraction (HFrEF). BACKGROUND: The splanchnic vascular capacity is a major determinant of the SBV, which in turn determines cardiac filling pressures and may be modifiable through SNB. METHODS: We analyzed data from 2 prospective, single-arm clinical studies in decompensated HFrEF (splanchnic HF-1; resting hemodynamics) and ambulatory heart failure (splanchnic HF-2; exercise hemodynamics). Patients underwent invasive hemodynamics and short-term SNB with local anesthetics. SBV was simulated using heart rate, cardiac output, central venous pressure, pulmonary capillary wedge pressure, systolic and diastolic systemic arterial and pulmonary artery pressures, and left ventricular ejection fraction. SBV is presented as ml/70 kg body weight. RESULTS: Mean left ventricular ejection fraction was 21 ± 11%. In patients with decompensated HFrEF (n = 11), the mean estimated SBV was 3,073 ±251 ml/70 kg. At 30 min post-SNB, the estimated SBV decreased by 10% to 2,754 ± 386 ml/70 kg (p = 0.003). In ambulatory HFrEF (n = 14) patients, the mean estimated SBV was 2,664 ± 488 ml/70 kg and increased to 3,243 ± 444 ml/70 kg (p < 0.001) at peak exercise. The resting estimated SBV was lower in ambulatory patients with HFrEF than in decompensated HFrEF (p = 0.019). In ambulatory patients with HFrEF, post-SNB, the resting estimated SBV decreased by 532 ± 264 ml/70 kg (p < 0.001). Post-SNB, with exercise, there was no decrease of estimated SBV out of proportion to baseline effects (p = 0.661). CONCLUSIONS: The estimated SBV is higher in decompensated than in ambulatory heart failure. SNB reduced the estimated SBV in decompensated and ambulatory heart failure. The reduction in estimated SBV was maintained throughout exercise.

Our aims are to explore the evidence for egg consumption effects on cardiovascular disease risk factors and the relationship between egg consumption with risk of coronary heart disease, stroke, heart failure, hypertension, and also to briefly discuss cardiovascular implications of egg consumption in individuals with diabetes and chronic kidney disease. Additionally, we provide a framework for health professionals when counseling patients on egg consumption as it relates to cardiovascular disease risk, and highlight areas where evidence is inconclusive and in need of future investigation. The relationship between egg consumption and cardiovascular diseases remains an area of significant debate among health professionals, as historically, eggs have been seen as potentially harmful if consumed frequently. The majority of existing evidence supports that assertion that moderate egg consumption of up to one egg per day in otherwise healthy individuals is not associated with a higher risk of ASCVD. In fact, eggs are a nutritious staple food that can be consumed in moderation in healthy individuals. Diet is all about balance. Moderate egg consumption, i.e., up to one egg per day, is not associated with a higher risk of cardiovascular diseases. Besides, eggs are an affordable food with a high content of many important nutrients.

Older adults with acute decompensated heart failure have persistently poor clinical outcomes. Cognitive impairment (CI) may be a contributing factor. However, the prevalence of CI and the relationship of cognition with other patient-centered factors such a physical function and quality of life (QOL) that also may contribute to poor outcomes are incompletely understood.Older (≥60 years) hospitalized patients with acute decompensated heart failure were assessed for cognition (Montreal Cognitive Assessment [MoCA]), physical function (Short Physical Performance Battery [SPPB], 6-minute walk distance [6MWD]), and QOL (Kansas City Cardiomyopathy Questionnaire, Short Form-12). Among patients (N = 198, 72.1 ± 7.6 years), 78% screened positive for CI (MoCA of26) despite rare medical record documentation (2%). Participants also had severely diminished physical function (SPPB 6.0 ± 2.5 units, 6MWD 186 ± 100 m) and QOL (scores of50). MoCA positively related to SPPB (ß = 0.47, P.001), 6MWD ß = 0.01, P = .006) and inversely related to Kansas City Cardiomyopathy Questionnaire Overall Score (ß = -0.05, P.002) and Short Form-12 Physical Component Score (ß = -0.09, P = .006). MoCA was a small but significant predictor of the results on the SPPB, 6MWD, and Kansas City Cardiomyopathy Questionnaire.Among older hospitalized patients with acute decompensated heart failure, CI is highly prevalent, is underrecognized clinically, and is associated with severe physical dysfunction and poor QOL. Formal screening may reduce adverse events by identifying patients who may require more tailored care.

Background Cardiovascular disease (CVD) hospitalizations declined worldwide during the COVID-19 pandemic. It is unclear how shelter-in-place orders affected acute CVD hospitalizations, illness severity, and outcomes. Hypothesis COVID-19 pandemic was associated with reduced acute CVD hospitalizations (heart failure [HF], acute coronary syndrome [ACS], and stroke [CVA]), and worse HF illness severity. Methods We compared acute CVD hospitalizations at Duke University Health System before and after North Carolina's shelter-in-place order (January 1-March 29 vs. March 30-August 31), and used parallel comparison cohorts from 2019. We explored illness severity among admitted HF patients using ADHERE ("high risk": >2 points) and GWTG-HF (">10%": >57 points) in-hospital mortality risk scores, as well as echocardiography-derived parameters. Results Comparing hospitalizations during January 1-March 29 (N = 1618) vs. March 30-August 31 (N = 2501) in 2020, mean daily CVD hospitalizations decreased (18.2 vs. 16.1 per day, p = .0036), with decreased length of stay (8.4 vs. 7.5 days, p = .0081) and no change in in-hospital mortality (4.7 vs. 5.3%, p = .41). HF hospitalizations decreased (9.0 vs. 7.7 per day, p = .0019), with higher ADHERE ("high risk": 2.5 vs. 4.5%; p = .030), but unchanged GWTG-HF (">10%": 5.3 vs. 4.6%; p = .45), risk groups. Mean LVEF was lower (39.0 vs. 37.2%, p = .034), with higher mean LV mass (262.4 vs. 276.6 g, p = .014). Conclusions CVD hospitalizations, HF illness severity, and echocardiography measures did not change between admission periods in 2019. Evaluating short-term data, the COVID-19 shelter-in-place order was associated with reductions in acute CVD hospitalizations, particularly HF, with no significant increase in in-hospital mortality and only minor differences in HF illness severity.

International audience; Background: Prior analyses suggest an association between formula-based plasma volume (PV) estimates and outcomes in heart failure (HF). We assessed the association between estimated PV status by the Duarte-ePV and Kaplan Hakim (KH-ePVS) formulas, and in-hospital and postdischarge clinical outcomes, in the ASCEND-HF trial.Methods and results: The KH-ePVS and Duarte-ePV were calculated on admission. We assessed associations with in-hospital worsening HF, 30-day composite cardiovascular mortality or HF rehospitalization and 180-day all-cause mortality. There were 6373 (89.2%), and 6354 (89.0%) patients who had necessary characteristics to calculate KH-ePVS and Duarte-ePV, respectively. There was no association between PV by either formula with in-hospital worsening HF. KH-ePVS showed a weak correlation with N-terminal prohormone BNP, and with measures of decongestion such as body weight change and urine output (r < 0.3 for all). Duarte-ePV was trending toward an association with worse 30-day (adjusted odds ratio 1.07, 95% confidence interval [CI] 1.00-1.15, P = .058), but not 180-day outcomes (adjusted hazard ratio 1.03, 95% CI 0.97-1.09, P = .289). A continuous KH-ePVS of >0 (per 10-unit increase) was associated with improved 30-day outcomes (adjusted odds ratio 0.75, 95% CI 0.62-0.91, P = .004). The continuous KH-ePVS was not associated with 180-day outcomes (adjusted hazard ratio 1.05, 95% CI 0.98-1.12, P = .139).Conclusions: Baseline PV estimates had a weak association with in-hospital measures of decongestion. The Duarte-ePV trended toward an association with early clinical outcomes in decompensated HF, and may improve risk stratification in HF.

We examined the relationship between pain severity and outcomes in patients with heart failure with reduced ejection fraction (HFrEF) in the HF-ACTION randomized controlled trial. Trends of health-related quality of life (HRQoL) measures grouped by patients' self-reported baseline bodily pain severity were compared using correlation tests, and the association between pain severity and clinical outcomes (including a primary composite endpoint of all-cause mortality and all-cause hospitalization) was assessed using multivariable adjusted analyses. Of the 2310 patients, 22.9% reported no pain, 45.8% very mild/mild, 24.9% moderate, and 6.4% severe/very severe. Greater pain severity was associated with worse HRQoL measures (EuroQoL-5D-3L and Kansas City Cardiomyopathy Questionnaire; both p < 0.0001). Compared to those reporting no pain, patients reporting severe/very severe pain had greater risk for the primary endpoint (adjusted hazard ratio 1.42, 95% confidence interval 1.11-1.83, p = 0.01). In patients with HFrEF, greater pain severity was associated with worse HRQoL and clinical outcomes. Trial Registration: NCT00047437.

Multiple medications are proven to reduce morbidity and mortality in patients with heart failure with reduced ejection fraction (HFrEF), but data regarding personalized approaches to optimize medication dosing remain limited. Current treatment guidelines recommend up-titration to target or maximally tolerated doses of these medications, yet use and dosing remain suboptimal in clinical practice. Body surface area (BSA) is a readily available clinical metric, used for dosing many medications, closely associated with blood pressure, renal function, and vascular congestion, and may influence efficacy, safety, and tolerability of HFrEF medications. In this review, we examine the rationale, strengths/weaknesses, and potential utility of BSA as a means of optimizing HFrEF medication use and dosing.

Purpose We aimed to 1) describe characteristics of patients with heart failure with preserved ejection fraction (HFpEF) enrolled in RELAX stratified by normal or elevated baseline serum uric acid (sUA) level; 2) evaluate the association between sUA level and surrogate clinical measures; and 3) assess associations between changes in sUA level over time and changes in surrogate clinical measures. Methods We analyzed 212 patients with HFpEF and normal or elevated (>6 mg/dL) baseline sUA measurements from the RELAX trial. Variables examined included clinical characteristics, cardiopulmonary exercise testing, 6-minute walk testing, quality of life, echocardiography, and serum biomarker testing. Baseline characteristics between groups were compared and scatter plots with quadratic regression lines and linear regression modeling were used to assess the relationship between baseline sUA and clinical measures. Kaplan–Meier curves were used to describe composite death or cardiovascular/renal hospitalization. Results The prevalence of elevated baseline sUA was 68.9%. Patients with elevated sUA had more baseline comorbidities and poorer functional status on cardiopulmonary exercise testing than those without. After adjustment, significant associations between baseline sUA levels and cystatin C, N-terminal pro B-type natriuretic peptide, high-sensitivity troponin I, and high-sensitivity C-reactive protein were identified. Higher baseline sUA was also associated with worsening peak VO2, 6-minute walk testing, and left ventricular mass. No significant association was found between baseline sUA levels and the composite of death or cardiovascular/renal hospitalization at 24 weeks. Conclusion sUA is an important marker of comorbidities and functional status in patients with HFpEF. Clinical trials of sUA-lowering therapies in patients with HFpEF are promising.

There is no clear consensus on a lower cutoff value for normal left ventricular ejection fraction (EF) and the prognostic implications of low normal EF (LNEF) are poorly understood, particularly in Blacks. Therefore, we investigated the association of LNEF and incident heart failure (HF) in a community-based cohort of Blacks. We studied 3,669 participants (mean age 54 years, 63% women) of the Jackson Heart Study without prevalent HF or coronary heart disease (CHD). Participants were divided into three groups: (1) Reduced EF (

The effects of glucagon-like peptide-1 receptor agonists (GLP-1RAs) on renal outcomes in patients with type 2 diabetes at high cardiovascular risk are modest or neutral. However, GLP-1RAs may confer clinical benefits in those at high risk of progressive renal function loss. We examined the effects of once-weekly exenatide (EQW) on estimated glomerular filtration rate (eGFR) slope and urinary albumin:creatinine ratio (UACR) as a function of baseline UACR in 3503 EXSCEL participants (23.7%) with eGFR data available and 2828 participants (19.2%) with UACR change data available. EQW improved eGFR slope assessed via mixed model repeated measures, compared with placebo, in participants with baseline UACR >100 mg/g (0.79 mL/min/1.73 m2/year [95% confidence interval {CI} 0.24–1.34]) and UACR >200 mg/g (1.32 mL/min/1.73 m2/year [95% CI 0.57–2.06]), but not at lower UACR thresholds. EQW reduced UACR, compared with placebo, assessed via analysis of covariance, consistently across subgroups with baseline UACR >30 mg/g (28.2% reduction), baseline UACR >100 mg (22.5% reduction) and baseline UACR >200 mg (34.5% reduction). This post hoc EXSCEL analysis suggests that EQW reduces UACR, with improvement in eGFR slope specifically in participants with elevated baseline UACR.

The coronavirus disease-2019 (COVID-19) pandemic has profoundly changed clinical care and research, including the conduct of clinical trials, and the clinical research ecosystem will need to adapt to this transformed environment. The Heart Failure Academic Research Consortium is a partnership between the Heart Failure Collaboratory and the Academic Research Consortium, composed of academic investigators from the United States and Europe, patients, the U.S. Food and Drug Administration, the National Institutes of Health, and industry members. A series of meetings were convened to address the challenges caused by the COVID-19 pandemic, review options for maintaining or altering best practices, and establish key recommendations for the conduct and analysis of clinical trials for cardiovascular disease and heart failure. This paper summarizes the discussions and expert consensus recommendations., Central Illustration, Highlights • The COVID-19 pandemic has profoundly affected patient care and the conduct of clinical trials. • HF-ARC scientific expert panel developed recommendations for the conduct and analysis of heart failure trials during the pandemic. • The HF-ARC consensus recommendations support ongoing clinical trials and strengthen the clinical trial ecosystem, which should have sustained benefits in the future.

Machine learning and artificial intelligence are generating significant attention in the scientific community and media. Such algorithms have great potential in medicine for personalizing and improving patient care, including in the diagnosis and management of heart failure. Many physicians are familiar with these terms and the excitement surrounding them, but many are unfamiliar with the basics of these algorithms and how they are applied to medicine. Within heart failure research, current applications of machine learning include creating new approaches to diagnosis, classifying patients into novel phenotypic groups, and improving prediction capabilities. In this paper, we provide an overview of machine learning targeted for the practicing clinician and evaluate current applications of machine learning in the diagnosis, classification, and prediction of heart failure.

The role of obesity in the pathogenesis of heart failure (HF), and in particular HF with preserved ejection fraction (HFpEF), has drawn significant attention in recent years. The prevalence of both obesity and HFpEF has increased worldwide over the past decades and when present concomitantly suggests an obese-HFpEF phenotype. Anthropometrics, including body mass index (BMI), waist circumference (WC), and waist-hip-ratio (WHR), are associated with incident HFpEF. However, the cardiovascular effects of obesity may actually be driven by the distribution of fat, which can accumulate in the epicardial, visceral, and subcutaneous compartments. Regional fat can be quantified using noninvasive imaging techniques, including computed tomography (CT), magnetic resonance imaging (MRI), and dual-energy X-ray absorptiometry (DXA). Regional variations in fat accumulation are associated with different HFpEF risk profiles, whereby higher epicardial and visceral fat have a much stronger association with HFpEF risk compared with elevated subcutaneous fat. Thus, regional adiposity may serve a pivotal role in the pathophysiology of HFpEF contributing to decreased cardiopulmonary fitness, impaired left ventricular compliance, upregulation of local and systemic inflammation, promotion of neurohormonal dysregulation, and increased intra-abdominal pressure and vascular congestion. Strategies to reduce total and regional adiposity have shown promise, including intensive exercise, dieting, and bariatric surgery programs, but few studies have focused on HFpEF-related outcomes among obese. Further understanding the role these variable fat depots play in the progression of HFpEF and HFpEF-related hospitalizations may provide therapeutic targets in treating the obese-HFpEF phenotype.

OptiVol (Medtronic PLC, Minneapolis, MN) is a diagnostic feature of some cardiac implantable electronic devices (CIEDs) based on changes in thoracic impedance (TI) over time. Changes in TI can predict heart failure (HF) hospitalizations and mortality in HF populations. However, the utility of this feature is unknown in patients with a left ventricular assist device (LVAD). To determine if OptiVol and TI correlate with clinical HF events in a population of LVAD patients, hospitalization outcomes were collected retrospectively from the electronic health records at a single academic medical center in 80 LVAD patients with an OptiVol-capable CIED. Demographics, medical history, and available clinical data were reviewed and reported. The primary outcomes of interest were TI and OptiVol trends before and after hospitalization, and association of trends before and after these events was evaluated. Most patients had a HeartMate II LVAD and most CIEDs were defibrillators, and 23 (29%) had at least one HF hospitalization during the study period. HF hospitalizations were preceded by signs of volume overload in Optivol (60%) and TI (78%) with recovery of these measures post hospitalization in 33% and 25% of patients, respectively. Monitoring of TI and OptiVol may be one effective component of HF management in LVAD patients as part of a comprehensive program.

Cardiovascular disease has an increased prevalence among patients with idiopathic pulmonary fibrosis (IPF). Cardiovascular disease and IPF share similar symptoms with overlapping demographics and risk factors for disease development. Common cellular mediators leading to disease development and progression have been identified in both the cardiovascular and pulmonary organ systems. In this context, discovery of new therapeutic targets and medical therapies could be mutually beneficial across cardiopulmonary diseases. Here we present (1) a clinical review of IPF for the cardiovascular clinician and (2) common cellular mechanisms responsible for fibrosis in the heart and lungs and (3) highlight future research considerations and the potential role of novel therapeutic agents which may be mutually beneficial in cardiac and pulmonary fibrosis.

Little is known about the impact of accountable care organizations (ACO) on hospitalized heart failure (HF) patients, a high-cost and high-risk population.We linked Medicare fee-for-service claims from 2013 to 2015 with data from American Heart Association Get With The Guidelines-HF registry to compare HF care, post-discharge outcomes, and total annual Medicare spending by ACO status at discharge.Using adjusted Cox models and accounting for competing risks of death, we compared all-cause mortality and readmission at 1 year by ACO status with reporting of hazard ratios (HR) and 99% confidence intervals (CI).The study included 45,259 HF patients from 300 hospitals, with 21.1% assigned to an ACO. Patient characteristics were similar between the two groups with a few exceptions. The ACO patients lived in geographic areas with higher median income ($54400 [IQR $48600-65900] vs $52300 [$45900-61200], P.0001). Compliance with four HF-specific quality measures was modestly higher in the ACO group (80% vs 76%, P.0001). In adjusted analysis, ACO status was associated with similar all-cause readmission (HR: 1.03; 99% CI: 0.99, 1.07) but lower risk of 1-year mortality (HR: 0.85; 99% CI: 0.85, 0.90) compared with non-ACO status. Median Medicare spending in the calendar year of hospitalization was similar (ACO $42,737 [IQR $23,011-72,667] vs non-ACO $42,586 [$22,896-72,518], P = 0.06).Among Medicare patients hospitalized for HF, participation in an ACO was associated with similar rates of all-cause readmission and no associated cost reductions compared with non-ACO status. There was a lower risk of 1-year mortality associated with ACO participation, which warrants further evaluation.

Background: Patients with heart failure (HF) have multiple coexisting comorbidities. The temporal trends in the burden of comorbidities and associated risk of mortality among patients with HF with preserved ejection fraction (HFpEF) and HF with reduced ejection fraction (HFrEF) are not well established. Methods: HF-related hospitalizations were sampled by stratified design from 4 US areas in 2005 to 2014 by the community surveillance component of the ARIC study (Atherosclerosis Risk in Communities). Acute decompensated HF was classified by standardized physician review and a previously validated algorithm. An ejection fraction Results: A total of 5460 hospitalizations (24 937 weighted hospitalizations) classified as acute decompensated HF had available ejection fraction data (53% female, 68% white, 53% HFrEF, 47% HFpEF). The average number of comorbidities was higher for patients with HFpEF versus HFrEF, both for women (5.53 versus 4.94; P P P -trendP for interaction by HF type=0.02). The associated mortality risk per 1 higher comorbidity also increased significantly over time for patients with HFpEF and HFrEF, as well ( P for interaction with time=0.002 and 0.02, respectively) Conclusions: The burden of comorbidities among hospitalized patients with acute decompensated HFpEF and HFrEF has increased over time, as has its associated mortality risk. Higher burden of comorbidities is associated with higher risk of mortality, with a stronger association noted among patients with HFpEF versus HFrEF.

Background Hypertensive diseases in pregnancy have been associated with altered cardiac structure and function, yet these associations have not been systematically investigated in larger populations including African Americans. We evaluated the relationships between hypertensive diseases in pregnancy with cardiac structure and function later in life in the Genetic Epidemiology Network of Arteriopathy (GENOA) study. Methods We investigated 1013 African American women sibships with echocardiographic measurements from the GENOA study (Phase II, 2000-05; Jackson, MS). Women were classified as self-reported nulliparous (n = 61), a history of normotensive pregnancies (n = 780), a history of a hypertensive pregnancies (n = 152), or a history of preeclampsia (n = 20). We compared adjusted associations among these 4 groups with echocardiographic measurements of cardiac structure and function using generalized estimating equations, accounting for familial clustering. Results Among 1013 women with echocardiographic data (mean age 62 ± 9.5 years), women with a history of hypertensive pregnancy had lower left ventricular ejection fraction (LVEF) (P = 0.043) compared to nulliparous women and higher left atrial systolic dimension (LASD) compared to women with a history of normotensive pregnancies (P = 0.010), After adjusting for cardiovascular risk factors. There were no statistically significant differences in other echocardiographic parameters among these groups. Conclusions A history of hypertension in pregnancy is associated with lower LVEF later in life, compared to nulliparous women and higher LASD compared to women with a history of normotensive pregnancies. However, given the multiple comparisons considered, this finding should be interpreted cautiously and requires further study.

Background An early report of recipient heart transplantation outcomes under the new U.S. heart allocation system introduced in late 2018 found a lower post-transplant survival rate compared with that of the prior system. Objectives The aim of this study was to examine recipient survival under the new system by using an updated dataset. Methods The 2015 to 2019 United Network for Organ Sharing registry was queried for adult heart transplant recipients, stratified according to whether the subjects were listed and underwent transplant before or after October 18, 2018, when the new allocation system was implemented. The association between allocation system and recipient mortality was analyzed by using the Kaplan-Meier method and multivariable Cox proportional hazards regression. Results A total of 7,119 recipients met inclusion criteria: 6,004 (84%) and 1,115 (16%) listed and undergoing transplant in the old and new allocation systems, respectively. This registry update included 576 new-system recipients, more than double the amount previously analyzed. Recipients from the new system were more likely to be bridged to transplant with temporary mechanical circulatory support devices instead of durable left ventricular assist devices and had longer graft ischemic times. After adjustment, the new system was not associated with poorer survival on Kaplan-Meier survival analysis (log-rank test; p = 0.075) or multivariable Cox proportional hazards modeling (adjusted hazard ratio: 1.18; 95% confidence interval: 0.90 to 1.55). Conclusions The short-term survival of recipients listed and receiving a transplant under the old and new allocation systems seems to be comparable. The modification to the allocation system has resulted in several changes to the clinical profiles of patients undergoing transplants that must be closely monitored in the coming years.

The role of percutaneous coronary interventions in addition to medical therapy for patients with stable coronary artery disease continues to be debated in routine clinical practice, despite more than 2 decades of randomized controlled trials. The residual uncertainty arises from particular challenges facing revascularization trials. Which endpoint do doctors care about, and which do patients care about? Which participants should be enrolled? What background medical therapy should we use? When is placebo control relevant? In this paper, we discuss how these questions can be approached and examine the merits and disadvantages of possible options. Engaging multiple stakeholders, including patients, researchers, regulators, and funders, to ensure the design elements are methodologically valid and clinically meaningful should be an aspirational goal in the development of future trials.

The infection caused by severe acute respiratory syndrome coronavirus-2, or COVID-19, can result in myocardial injury, heart failure, and arrhythmias. In addition to the viral infection itself, investigational therapies for the infection can interact with the cardiovascular system. As cardiologists and cardiovascular service lines will be heavily involved in the care of patients with COVID-19, our division organized an approach to manage these complications, attempting to balance resource utilization and risk to personnel with optimal cardiovascular care. The model presented can provide a framework for other institutions to organize their own approaches and can be adapted to local constraints, resource availability, and emerging knowledge.

Background Ivabradine is guideline-recommended to reduce heart failure (HF) hospitalization in patients with stable chronic HF with reduced ejection fraction (EF). Ivabradine initiation following acute HF has had limited evaluation, and there are few randomized data in US patients. The PredischaRge initiation of Ivabradine in the ManagEment of Heart Failure (PRIME-HF) study was conducted to address predischarge ivabradine initiation in stabilized acute HF patients. Methods PRIME-HF was an investigator-initiated, randomized, open-label study of predischarge initiation of ivabradine versus usual care. Eligible patients were hospitalized for acute HF but stabilized, with EF ≤35%, on maximally tolerated β-blocker and in sinus rhythm with heart rate ≥70 beats/min. Ivabradine was acquired per routine care. The primary end point was the proportion of patients on ivabradine at 180 days. Additional end points included heart rate change, patient-reported outcomes, β-blocker use/dose, and safety events (symptomatic bradycardia and hypotension). Results Overall, 104 patients (36% women, 64% African American) were randomized, and the study was terminated early because of funding limitations. At 180 days, 21 of 52 (40.4%) of patients randomized to predischarge initiation were treated with ivabradine compared with 6 of 52 (11.5%) randomized to usual care (odds ratio 5.19, 95% CI 1.88-14.33, P = .002). The predischarge initiation group experienced greater reduction in heart rate through 180 days (mean −10.0 beats/min, 95% CI −15.7 to −4.3 vs 0.7 beats/min, 95% CI −5.4 to 6.7, P = .011). Patient-reported outcomes, β-blocker use/dose, and safety events were similar (all P > .05). Conclusions Ivabradine initiation prior to discharge among stabilized HF patients increased ivabradine use at 180 days and lowered heart rates without reducing β-blockers or increasing adverse events. As the trial did not achieve the planned enrollment, additional studies are needed.

Background: EXSCEL (Exenatide Study of Cardiovascular Event Lowering) assessed the impact of once-weekly exenatide 2 mg versus placebo in patients with type 2 diabetes mellitus, while aiming for glycemic equipoise. Consequently, greater drop-in of open-label glucose-lowering medications occurred in the placebo group. Accordingly, we explored the potential effects of their unbalanced use on major adverse cardiovascular events (MACE), defined as cardiovascular death, nonfatal myocardial infarction or nonfatal stroke, and all-cause mortality (ACM), given that some of these agents are cardioprotective. Methods: Cox hazard models were performed by randomized treatment for drug classes where >5% open-label drop-in glucose-lowering medication occurred, and for glucagon-like peptide-1 receptor agonists (GLP-1 RAs; 3.0%) using three methodologies: drop-in visit right censoring, inverse probability for treatment weighting (IPTW), and applying drug class risk reductions. Results: Baseline glucose-lowering medications for the 14 752 EXSCEL participants (73.1% with previous cardiovascular disease) did not differ between treatment groups. During median 3.2 years follow-up, open-label drop-in occurred in 33.4% of participants, more frequently with placebo than exenatide (38.1% versus 28.8%), with metformin (6.1% versus 4.9%), sulfonylurea (8.7% versus 6.9%), dipeptidyl peptidase-4 inhibitors (10.6% versus 7.5%), SGLT-2i (10.3% versus 8.1%), GLP-1 RA (3.4% versus 2.4%), and insulin (13.8% versus 9.4%). The MACE effect size was not altered meaningfully by right censoring, but the favorable HR for exenatide became nominally significant in the sulfonylurea and any glucose-lowering medication groups, while the ACM HR and p-values were essentially unchanged. IPTW decreased the MACE HR from 0.91 ( P =0.061) to 0.85 ( P =0.008) and the ACM HR from 0.86 ( P =0.016) to 0.81 ( P =0.012). Application of literature-derived risk reductions showed no meaningful changes in MACE or ACM HRs or P values, although simulations of substantially greater use of drop-in cardioprotective glucose-lowering agents demonstrated blunting of signal detection. Conclusions: EXSCEL-observed HRs for MACE and ACM remained robust after right censoring or application of literature-derived risk reductions, but the exenatide versus placebo MACE effect size and statistical significance were increased by IPTW. Effects of open-label drop-in cardioprotective medications need to be considered carefully when designing, conducting, and analyzing cardiovascular outcome trials of glucose-lowering agents under the premise of glycemic equipoise.

AIMS In Aldosterone Targeted Neurohormonal Combined with Natriuresis Therapy in Heart Failure (ATHENA-HF), high-dose spironolactone (100 mg daily) did not improve efficacy endpoints over usual care [placebo or continued low-dose spironolactone (25 mg daily) in patients already receiving spironolactone] in the treatment of acute heart failure (HF). We hypothesized that low concentrations of the long-acting active metabolites of spironolactone [canrenone and 7α-thiomethylspironolactone (7α-TMS)] in the high-dose group could have contributed to these neutral results. METHODS AND RESULTS In patients randomized to high-dose spironolactone not previously treated with spironolactone (high-dose-naive, n = 112), concentrations of canrenone and 7α-TMS increased at 48 and 96 h compared to baseline, and between 48 and 96 h (all P
