Background: Significant gap remains in the implementation of guideline-directed medical therapy (GDMT) in patients with heart failure after a hospitalization. We aimed to evaluate the use and titration of GDMT at discharge and over a 12-month period after hospital discharge and to identify factors associated with GDMT use and titration., Methods and Results: The CONNECT-HF (Care Optimization Through Patient and Hospital Engagement Clinical Trial for Heart Failure) trial evaluated the effect of a hospital and postdischarge quality improvement intervention in participants with heart failure with reduced ejection fraction. In this secondary analysis, we examined use and titration to at least 50% of the target dose of GDMTs at hospital discharge and over time. Among 4646 participants (mean age 63 years, 34% women), GDMT use did not numerically improve from discharge to 12 months: beta blockers (84%-78%), angiotensin-converting enzyme inhibitors/angiotensin II receptor blockers/angiotensin receptor-neprilysin inhibitors (73%-65%), mineralocorticoid receptor antagonists (39%-36%), and sodium-glucose cotransporter 2 inhibitors (1.5%-2.1%). Achieving ≥50% of the target dose also showed little change over 12 months: beta blockers (35%-32%), angiotensin-converting enzyme inhibitors/angiotensin II receptor blockers/angiotensin receptor-neprilysin inhibitors (28%-25%). For all medications, use of GDMT at discharge was associated with the use and achieving ≥50% of the target dose at 12 months., Conclusions: Following a hospitalization for heart failure, GDMT use remained low and did not numerically improve over 12 months. Use of GDMT at discharge was significantly associated with the use of GDMT over time, highlighting the importance of initiating GDMT during hospitalization.

Background and Aims: Heart failure endpoints in cardiovascular outcome trials are commonly identified through centralized adjudication of investigator-reported events. It remains unclear whether central adjudication improves the accuracy of treatment effect estimates in terms of log[hazard ratios (HR)]., Methods: Data from seven cardiovascular outcome trials with >1000 patients that included centrally adjudicated heart failure outcomes were utilized to assess (i) the concordance between investigator-reported and centrally adjudicated heart failure and cardiovascular death events; (ii) rates of subsequent all-cause mortality following positively vs. negatively adjudicated heart failure events; and (iii) the correlation of log(HR) based on centrally adjudicated vs. investigator-reported events., Results: Positive adjudication rates for investigator-reported events varied widely across trials, but were generally higher for cardiovascular death (range: 87.9%-99.2%) than for heart failure hospitalization (range: 61.6%-88.0%). The risk for subsequent all-cause death was similar for positively and negatively adjudicated heart failure hospitalizations. Log(HR) correlated well for cardiovascular death [R2 = .80, 95% credible interval (CrI): 0.53-0.93] and the composite of cardiovascular death or heart failure hospitalization (R2 = .79, 95% CrI: 0.46-0.93), but less for heart failure hospitalization (R2 = .57, 95% CrI: 0.10-0.83)., Conclusions: Positive adjudication rates were lower for heart failure events than cardiovascular death, but even negatively adjudicated heart failure events are prognostically important. Central adjudication of events did not alter the results (precision or estimated log(HR)), though some variation was observed, depending on the indication. The results suggest that the decision to pursue centralized adjudication of heart failure events in a specific trial may need to be individualized., (© The Author(s) 2024.

Background: Randomized controlled trials typically require study-specific visits, which can burden participants and sites. Remote follow-up, such as centralized call centers for participant-reported or site-reported, holds promise for reducing costs and enhancing the pragmatism of trials. In this secondary analysis of the CONNECT-HF (Care Optimization Through Patient and Hospital Engagement For HF) trial, we aimed to evaluate the completeness and validity of the remote follow-up process., Methods and Results: The CONNECT-HF trial evaluated the effect of a post-discharge quality-improvement intervention for heart failure compared to usual care for up to 1 year. Suspected events were reported either by participants or by health care proxies through a centralized call center or by sites through medical-record queries. When potential hospitalization events were suspected, additional medical records were collected and adjudicated. Among 5942 potential hospitalizations, 18% were only participant-reported, 28% were reported by both participants and sites, and 50% were only site-reported. Concordance rates between the participant/site reports and adjudication for hospitalization were high: 87% participant-reported, 86% both, and 86% site-reported. Rates of adjudicated heart failure hospitalization events among adjudicated all-cause hospitalization were lower but also consistent: 45% participant-reported, 50% both, and 50% site-reported., Conclusions: Participant-only and site-only reports missed a substantial number of hospitalization events. We observed similar concordance between participant/site reports and adjudication for hospitalizations. Combining participant-reported and site-reported outcomes data is important to capture and validate hospitalizations effectively in pragmatic heart failure trials., Competing Interests: Disclosures ADV reports research funding through his institution from Biofourmis, Bodyport, Cytokinetics, American Regent, NIH and NHLBI, Novartis, and Story Health, and provides consulting services for and/or receives honoraria from Abiomed, Cardionomic, LivaNova, Natera, NovoNordisk, Story Health, and Zoll.

Background: Multimorbidity frequently occurs in patients with acute heart failure (AHF). The co-occurrence of comorbidities often follows specific patterns., Objectives: This study investigated multimorbidity subtypes and their associations with clinical outcomes., Methods: From the prospective RELAX-AHF-2 (Relaxin for the Treatment of Acute Heart Failure-2) trial, 6,545 patients (26% with HF with preserved ejection fraction, defined as LVEF ≥50%) were classified into multimorbidity groups using latent class analysis. The association between subgroups and clinical outcomes was examined. Validation of these findings was conducted in the RELAX-AHF trial, which comprised 1,161 patients., Results: Five distinct multimorbidity groups emerged: 1) diabetes and chronic kidney disease (CKD) (often male, high prevalence of CKD and diabetes mellitus); 2) ischemic (ischemic HF); 3) elderly/atrial fibrillation (AF) (oldest, high prevalence of AF); 4) metabolic (obese, hypertensive, more often HF with preserved ejection fraction); and 5) young (fewest comorbidities). After adjusting for confounders, patients in the diabetes and CKD (HR: 1.80; 95% CI: 1.50-2.20), elderly/AF (HR: 1.42; 95% CI: 1.20-1.70), and metabolic (HR: 1.40; 95% CI: 1.20-1.80) groups had higher rates of the composite outcome than patients in the young group, primarily driven by differences in rehospitalization. Treatment allocation (placebo or serelaxin) modified these associations (P interaction  <0.001). Serelaxin-treated patients in the young group were associated with a lower risk for all-cause mortality (HR: 0.59; 95% CI: 0.40-0.90). Similarly, patients from the RELAX-AHF trial clustered in 5 multimorbidity groups. The clinical characteristics and associations with outcomes could also be validated., Conclusions: Comorbidities naturally clustered into 5 mutually exclusive groups in RELAX-AHF-2, showing variations in clinical outcomes. These data emphasize that the specific combination of comorbidities can influence adverse outcomes and treatment responses in patients with AHF., Competing Interests: Funding Support and Author Disclosures This study was funded by the PROMINENT project (funding from the European Union’s Horizon 2020 research and innovation program under the Marie Skłodowska-Curie grant agreement number 754425).

Background: Patients with obesity and advanced heart failure requiring left ventricular assist device (LVAD) support are more likely to experience LVAD complications and may be disproportionately Black and/or female when compared to patients without obesity. Among these patients, obesity may represent a barrier to transplant eligibility and a marker of inequity in heart transplantation and health outcomes in advanced heart failure., Methods: To better understand this issue at our institution, we examined our active LVAD cohort and found that almost one-third of all patients had severe obesity with BMI ≥ 35 kg/m 2 ., Results: Patients with LVADs and severe obesity were significantly younger and more likely to self-identify as Black, and numerically more likely to be female., Conclusion: Weight management in this group represents a vital area for improved equity in health outcomes and barriers to heart transplantation., Trial Registration: NA., Competing Interests: Conflict of interest CM, SB, and JH have no disclosures.

Purpose of Review: To review ongoing and planned clinical trials of weight loss among individuals with or at high risk of heart failure., Recent Findings: Intentional weight loss via semaglutide among persons with heart failure and preserved ejection fraction and obesity significantly improves weight loss and health status as assessed by the KCCQ-CSS score and is associated with improvements in 6-min walk test. Ongoing and planned trials will explore the role of intentional weight loss with treatments such as semaglutide or tirzepatide for individuals with heart failure across the entire ejection fraction spectrum., (© 2024.

Aims: The PARACOR-19 randomized controlled trial (RCT) was designed to examine the effects of sacubitril/valsartan on markers of cardiac injury, inflammation, structure, and function among patients who have recovered from acute coronavirus disease 2019 (COVID-19) infection., Methods and Results: PARACOR-19 was a single-centre, double-blind RCT of patients with cardiovascular risk factors and a history of COVID-19 infection 4-16 weeks prior to enrolment. Patients were randomized to sacubitril/valsartan (titrated to the maximum dose of 97/103 mg twice daily) versus matching placebo. Co-primary endpoints were change from baseline to 12 weeks in high-sensitivity cardiac troponin T (hs-cTnT) and soluble ST2 (sST2). Exploratory endpoints included change from baseline to 12 weeks in additional circulating biomarkers. Overall, 42 patients were randomized between August 2021 and March 2023 (n = 20 sacubitril/valsartan, n = 22 placebo). Median (25th-75 th ) time from COVID-19 diagnosis to enrolment was 67 (48-80) days. Median age was 67 (62-71) years, 48% were female, and 91% were White. Compared with placebo, sacubitril/valsartan did not have a significant effect on the co-primary endpoints of change from baseline in hs-TnT and sST2 (all p ≥ 0.29). In exploratory analyses, sacubitril/valsartan led to a 46% greater reduction in N-terminal pro-B-type natriuretic peptide (NT-proBNP) and 51% greater reduction in C-terminal telopeptide of collagen type I (CITP). Permanent drug discontinuation occurred in four patients in the sacubitril/valsartan group and three patients in the placebo group. There were no deaths and one patient was hospitalized in each group., Conclusion: In this pilot RCT of patients who recovered from acute COVID-19, sacubitril/valsartan did not lower hs-cTnT or sST2 compared with placebo. Exploratory analyses suggested potential benefits of sacubitril/valsartan on cardiac wall stress and collagen turnover as measured by NT-proBNP and CITP. Sacubitril/valsartan was well tolerated., Clinical Trial Registration: ClinicalTrials.gov NCT04883528., (© 2024 European Society of Cardiology.)

Background: Omecamtiv mecarbil improves outcomes in patients with heart failure and reduced ejection fraction (HFrEF). We examined the relationship between baseline troponin levels, change in troponin levels over time and the treatment effect of omecamtiv mecarbil in patients enrolled in the Global Approach to Lowering Adverse Cardiac Outcomes through Improving Contractility in Heart Failure (GALACTIC-HF) trial (NCT02929329)., Methods: GALACTIC-HF was a double-blind, placebo-controlled trial that randomized 8256 patients with symptomatic HFrEF to omecamtiv mecarbil or placebo. High-sensitivity troponin I (cTnI) was measured serially at a core laboratory. We analyzed the relationship between both baseline cTnI and change in cTnI concentrations with clinical outcomes and the treatment effect of omecamtiv mecarbil., Results: Higher baseline cTnI concentrations were associated with a risk of adverse outcomes (hazard ratio for the primary endpoint of time to first HF event or CV death = 1.30; 95% CI 1.28, 1.33; P < 0.001 per doubling of baseline cTnI). Although the incidence of safety outcomes was higher in patients with higher baseline cTnI, there was no difference between treatment groups. Treatment with omecamtiv mecarbil led to a modest increase in cTnI that was related to plasma concentrations of omecamtiv mecarbil, and it peaked at 6 weeks. An increase in troponin from baseline to week 6 was associated with an increased risk of the primary endpoint (P < 0.001), which was similar, regardless of treatment assignment (P value for interaction = 0.2)., Conclusions: In a cohort of patients with HFrEF, baseline cTnI concentrations were strongly associated with adverse clinical outcomes. Although cTnI concentrations were higher in patients treated with omecamtiv mecarbil, we did not find a differential effect of omecamtiv mecarbil on either safety or efficacy based on baseline cTnI status or change in cTnI., Competing Interests: DISCLOSURES GMF has received research grants from NHLBI, American Heart Association, Amgen, Bayer, BMS, Merck, Cytokinetics, and CSL-Behring; he has acted as a consultant to Novartis, Amgen, BMS, Cytokinetics, Medtronic, Cardionomic, Boehringer-Ingelheim, American Regent, Abbott, Astra-Zeneca, Reprieve, Myovant, Sequana, Windtree Therapuetics, and Whiteswell and has served on clinical endpoint committees/data safety monitoring boards for Amgen, Merck, Medtronic, EBR Systems, V-Wave, LivaNova, Siemens, and Rocket Pharma.

Objectives: To assess tissue Doppler-derived mitral annular isovolumic contraction velocity (ICV) after starting sacubitril/valsartan (sac/val) for the treatment of heart failure with reduced ejection fraction (HFrEF) and left ventricular [LV] EF < 40%)., Background: ICV may inform load-independent systolic function; combining ICV and LVEF may improve assessment of LV contractility., Methods: Among 651 participants with HFrEF treated with sac/val, echocardiograms were performed at baseline, 6 and 12 months. Pretreatment median ICVs and LVEFs were used for classification to predict LV reverse remodeling, health status using the Kansas City Cardiomyopathy Questionnaire, and biomarker concentrations., Results: The mean age was 64.6 ± 12.4 years, and 28% were women, baseline LVEF: 28.9% ± 6.9%. Compared to baseline, median ICV increased post sac/val therapy (4.6 [3.5, 6.1] vs 4.9 [3.6, 6.4]; P = 0.005). ICV added value to separate and combined models of biomarkers and clinical and echocardiographic variables for prediction of post-therapy EF recovery. Classification using baseline ICV/EF yielded relatively equal numbers in 4 groups based on low/high ICV or LVEF. Most deleterious results for remodeling, health status and biomarkers were found in patients with low ICV/low EF, whereas patients with high ICV/high EF had the best profiles; other groups were intermediate. Significant shifts toward better ICV/EF profiles were noted post sac/val treatment compared to baseline, with doubling of high ICV/high EF (241 [60%] vs 123 [31%]) and 78% reduction of low ICV/low EF (28 [7%] vs 125 [32%])., Conclusions: In HFrEF, ICV adds to the profiling of systolic function and represents an independent predictor of reverse cardiac remodeling after treatment with sac/val. ICV changes may be used for assessment of treatment responses., Competing Interests: Disclosures None., (Copyright © 2023 The Author(s). Published by Elsevier Inc. All rights reserved.)

Background: In heart failure (HF) trials, there has been an emphasis on utilizing more patient-centered outcomes, including quality of life (QoL) and days alive and out of hospital. We aimed to explore the impact of QoL adjusted days alive and out of hospital as an outcome in 2 HF clinical trials., Methods: Using data from 2 trials in HF (Guiding Evidence Based Therapy Using Biomarker Intensified Treatment in Heart Failure [GUIDE-IT] and Study of Dietary Intervention under 100 mmol in Heart Failure [SODIUM-HF]), we determined treatment differences using percentage days alive and out of hospital (%DAOH) adjusted for QoL at 18 months as the primary outcome. For each participant, %DAOH was calculated as a ratio between days alive and out of hospital/total follow-up. Using a regression model, %DAOH was subsequently adjusted for QoL measured by the Kansas City Cardiomyopathy Questionnaire Overall Summary Score., Results: In the GUIDE-IT trial, 847 participants had a median baseline Kansas City Cardiomyopathy Questionnaire Overall Summary Score of 59.0 (interquartile range, 40.8-74.3), which did not change over 18 months. %DAOH was 90.76%±22.09% in the biomarker-guided arm and 88.56%±25.27% in the usual care arm. No significant difference in QoL adjusted %DAOH was observed (1.09% [95% CI, -1.57% to 3.97%]). In the SODIUM-HF trial, 796 participants had a median baseline Kansas City Cardiomyopathy Questionnaire Overall Summary Score of 69.8 (interquartile range, 49.3-84.3), which did not change over 18 months. %DAOH was 95.69%±16.31% in the low-sodium arm and 95.95%±14.76% in the usual care arm. No significant difference was observed (1.91% [95% CI, -0.85% to 4.77%])., Conclusions: In 2 large HF clinical trials, adjusting %DAOH for QoL was feasible and may provide complementary information on treatment effects in clinical trials., Competing Interests: Disclosures Dr Felker reported receiving grant support from Merck and personal fees from Medtronic, Bristol Myers Squibb, Trevena, GlaxoSmithKline, Myokardia, and Stealth BioTherapeutics.

Purpose of Review: Obesity is associated with cardiovascular (CV) conditions, including but not limited to atherosclerotic disease, heart failure, and atrial fibrillation. Despite this, the impact of intentional weight loss on CV outcomes for persons with obesity and established CV conditions remains poorly studied. New and emerging pharmacologic therapies for weight loss primarily targeting the incretin/nutrient sensing axes induce substantial and sustained weight loss. The glucagon-like-peptide 1 receptor agonists (GLP-1 RA) liraglutide and semaglutide have US FDA approval for the treatment of obesity, and the application for an obesity indication for the dual GLP-1/glucose-dependent insulinotropic polypeptide (GIP) receptor agonist tirzepatide is presently under FDA review. Extensive phase II and IIIa randomized controlled trials are underway evaluating permutations of combined GLP-1 RA, GIP receptor agonist, GIP receptor antagonist, and glucagon receptor agonists. Clinical outcome trials of these therapies in persons with obesity at high risk of established CV conditions should make it possible to estimate the role of intentional weight loss in managing CV risk via these medications., Recent Findings: High-dose once weekly injectable semaglutide (2.4 mg/week) use among persons with obesity and heart failure with preserved ejection fraction was effective at both reducing weight and improving health status; exercise capacity was also improved. Ongoing CV outcome trials of oral semaglutide and once weekly injectable tirzepatide will help to establish the role of these therapies among persons with other CV conditions. In addition to these two therapies targeting a CV claim or indication, many other new therapeutics for weight loss, as reviewed, are currently in development. The impact of pharmacologic-induced weight loss on CV conditions for persons with obesity and established CV conditions is currently under investigation for multiple agents. These therapies may offer new avenues to manage CV risk in persons with obesity and with established or at high risk for CV disease., (© 2024.

Background: Tricuspid regurgitation (TR) is common and is associated with poor outcomes in patients with heart failure (HF). However, data with adjudicated events from fully characterized patients with heart failure with reduced ejection fraction (HFrEF) are lacking., Objectives: This study sought to explore the association between mild or moderate/severe TR and clinical outcomes of patients with HFrEF., Methods: GALACTIC-HF (Global Approach to Lowering Adverse Cardiac Outcomes Through Improving Contractility in Heart Failure) was a double-blind, placebo-controlled randomized trial comparing omecamtiv mecarbil vs placebo in patients with symptomatic HFrEF., Results: Among the 8,232 patients analyzed in the GALACTIC-HF trial, 8,180 (99%) had data regarding baseline TR (none: n = 6,476 [79%], mild: n = 919 [11%], and moderate/severe: n = 785 [10%]). The primary composite outcome of a first HF event or cardiovascular death occurred in 2,368 (36.6%) patients with no TR, 353 (38.4%) patients with mild TR, and 389 (49.6%) patients with moderate/severe TR. Moderate/severe TR was independently associated with a higher relative risk of the primary composite outcome compared with either no TR (adjusted HR: 1.12 [95% CI: 1.01-1.26]; P = 0.046) or no/mild TR (adjusted HR: 1.14 [95% CI: 1.02-1.27]; P = 0.025) driven predominantly by HF events. The association between moderate/severe TR and clinical outcomes was more pronounced in outpatients with worse renal function, higher left ventricular ejection fraction, and lower N-terminal pro-B-type natriuretic peptide and bilirubin levels. The beneficial treatment effect of omecamtiv mecarbil vs placebo on clinical outcomes was not modified by TR., Conclusions: In symptomatic patients with HFrEF, baseline moderate/severe TR was independently associated with cardiovascular death or HF events driven predominantly by HF events.

Background: Although clinical studies have demonstrated the association between a single N-terminal pro-B-type natriuretic peptide (NT-proBNP) measurement and clinical outcomes in chronic heart failure, the biomarker is frequently measured serially in clinical practice., Objectives: The aim of this study was to determine the added prognostic value of repeated NT-proBNP measurements compared with single measurements alone for chronic heart failure patients., Methods: In the GUIDE-IT (Guiding Evidence Based Therapy Using Biomarker Intensified Treatment in Heart Failure) study, 894 study participants with chronic heart failure with reduced ejection fraction were enrolled at 45 outpatient sites in the United States and Canada. Repeated NT-proBNP levels were measured over a 2-year study period. Associations between repeated NT-proBNP measurements and trial endpoints were assessed using a joint longitudinal and survival model., Results: After adjustment for baseline covariates, each doubling of the baseline NT-proBNP level was associated with a HR of 1.17 (95% CI: 1.08-1.28; P = 0.0003) for the primary trial endpoint of cardiovascular death or heart failure hospitalization. Serial measurements increased the adjusted HR for the primary trial endpoint to 1.66 (95% CI: 1.50-1.84; P < 0.0001), and a similar increased risk was observed across secondary trial endpoints. In joint modeling, an increase in NT-proBNP occurred weeks before the onset of adjudicated events., Conclusions: Repeated NT-proBNP measurements are a strong predictor of outcomes in heart failure with reduced ejection fraction with an increase in concentration occurring well before event onset. These results may support routine NT-proBNP monitoring to assist in clinical decision making.

Heart failure (HF) is a complex syndrome traditionally classified by left ventricular ejection fraction (LVEF) cutpoints. Although LVEF is prognostic for risk of events and predictive of response to some HF therapies, LVEF is a continuous variable and cutpoints are arbitrary, often based on historical clinical trial enrichment decisions rather than physiology. Holistic evaluation of the treatment effects for therapies throughout the LVEF range suggests the standard categorization paradigm for HF merits modification. The multidisciplinary Heart Failure Collaboratory reviewed data from large-scale HF clinical trials and found that many HF therapies have demonstrated therapeutic benefit across a large range of LVEF, but specific treatment effects vary across that range. Therefore, HF should practically be classified by association with an LVEF that is reduced or not reduced, while acknowledging uncertainty around the precise LVEF cutpoint, and future research should evaluate new therapies across the continuum of LVEF., Competing Interests: Funding Support and Author Disclosures Dr Ibrahim has received consulting fees from Cytokinetics.

Background: In the Global Approach to Lowering Adverse Cardiac Outcomes Through Improving Contractility in Heart Failure (GALACTIC-HF) trial, omecamtiv mecarbil, compared with placebo, reduced the risk of worsening heart failure (HF) events, or cardiovascular death in patients with HF and reduced ejection fraction. The primary aim of this prespecified analysis was to evaluate the safety and efficacy of omecamtiv mecarbil by randomization setting, that is, whether participants were enrolled as outpatients or inpatients., Methods and Results: Patients were randomized either during a HF hospitalization or as an outpatient, within one year of a worsening HF event (hospitalization or emergency department visit). The primary outcome was a composite of worsening HF event (HF hospitalization or an urgent emergency department or clinic visit) or cardiovascular death. Of the 8232 patients analyzed, 2084 (25%) were hospitalized at randomization. Hospitalized patients had higher N-terminal prohormone of B-type natriuretic peptide concentrations, lower systolic blood pressure, reported more symptoms, and were less frequently treated with a renin-angiotensin system blocker or a beta-blocker than outpatients. The rate (per 100 person-years) of the primary outcome was higher in hospitalized patients (placebo group = 38.3/100 person-years) than in outpatients (23.1/100 person-years); adjusted hazard ratio 1.21 (95% confidence interval 1.12-1.31). The effect of omecamtiv mecarbil versus placebo on the primary outcome was similar in hospitalized patients (hazard ratio 0.89, 95% confidence interval 0.78-1.01) and outpatients (hazard ratio 0.94, 95% confidence interval 0.86-1.02) (interaction P = .51)., Conclusions: Hospitalized patients with HF with reduced ejection fraction had a higher rate of the primary outcome than outpatients. Omecamtiv mecarbil decreased the risk of the primary outcome both when initiated in hospitalized patients and in outpatients., Competing Interests: Declaration of Competing Interest K.F.D. has received financial support to attend educational meetings from Cytokinetics during the conduct of the study, personal fees from AstraZeneca, consulting fees from Us2.ai and research grants to his institution from AstraZeneca and Boehringer Ingelheim outside the submitted work.

Obesity is associated with incident heart failure (HF), independent of other cardiovascular risk factors. Despite rising rates of both obesity and incident HF, the associations remain poorly understood between: 1) obesity and HF outcomes; and 2) weight loss and HF outcomes. Evidence shows that patients with HF and obesity have high symptom burdens, lower exercise capacity, and higher rates of hospitalization for HF when compared with patients with HF without obesity. However, the impact of weight loss on these outcomes for patients with HF and obesity remains unclear. Recent advances in medical therapies for weight loss have offered a new opportunity for significant and sustained weight loss. Ongoing and recently concluded cardiovascular outcomes trials will offer new insights into the role of weight loss through these therapies in preventing HF and mitigating HF outcomes and symptom burdens among patients with established HF, particularly HF with preserved ejection fraction., Competing Interests: Funding Support and Author Disclosures Dr Felker has received research grants from the National Heart, Lung and Blood Institute, the American Heart Association, Amgen, Bayer, Bristol-Myers Squibb, Merck, Cytokinetics, and CSL Behring; has acted as a consultant to Novartis, Amgen, Bristol-Myers Squibb, Cytokinetics, Medtronic, Cardionomic, Boehringer Ingelheim, American Regent, Abbott, AstraZeneca, Reprieve, Myovant, Sequana, Windtree Therapeutics, and Whiteswell; and has served on clinical endpoint committees or data safety monitoring boards for Amgen, Merck, Medtronic, EBR Systems, V-Wave, LivaNova, Siemens, and Rocket Pharma.

Acute decompensated heart failure (ADHF) is one of the most common reasons for hospitalizations or urgent care and is associated with poor outcomes. Therapies shown to improve outcomes are limited, however, and innovation in pharmacologic and device-based therapeutics are therefore actively being sought. Standardizing definitions for ADHF and its trajectory is complex, limiting the generalizability and translation of clinical trials to effect clinical care and policy change. The Heart Failure Collaboratory is a multistakeholder organization comprising clinical investigators, clinicians, patients, government representatives (including U.S. Food and Drug Administration and National Institutes of Health participants), payors, and industry collaborators. The following expert consensus document is the product of the Heart Failure Collaboratory convening with the Academic Research Consortium, including members from academia, the U.S. Food and Drug Administration, and industry, for the purposes of proposing standardized definitions for ADHF and highlighting important endpoint considerations to inform the design and conduct of clinical trials for drugs and devices in this clinical arena., Competing Interests: Funding Support and Author Disclosures Dr Lala is a Speakers Bureau member for Abiomed, Cytokinetics, Novartis, and Zoll; and performs contracted research for Merck.

Aim: To investigate the effects of Cimlanod, a nitroxyl donor with vasodilator properties, on water and salt excretion after an administration of an intravenos bolus of furosemide., Methods and Results: In this randomized, double-blind, mechanistic, crossover trial, 21 patients with left ventricular ejection fraction <45%, increased plasma concentrations of N-terminal pro-B-type natriuretic peptide (NT-proBNP) and receiving loop diuretics were given, on separate study days, either an 8 h intravenous (IV) infusion of cimlanod (12 μg/kg/min) or placebo. Furosemide was given as a 40 mg IV bolus four hours after the start of infusion. The primary endpoint was urine volume in the 4 h after the bolus of furosemide during infusion of cimlanod compared with placebo. Median NT-proBNP at baseline was 1487 (interquartile range: 847-2665) ng/L. Infusion of cimlanod increased cardiac output and reduced blood pressure without affecting cardiac power index consistent with its vasodilator effects. Urine volume in the 4 h post-furosemide was lower with cimlanod (1032 ± 393 ml) versus placebo (1481 ± 560 ml) (p = 0.002), as were total sodium excretion (p = 0.004), fractional sodium excretion (p = 0.016), systolic blood pressure (p < 0.001), estimated glomerular filtration rate (p = 0.012), and haemoglobin (p = 0.010), an index of plasma volume expansion., Conclusions: For patients with heart failure and congestion, vasodilatation with agents such as cimlanod reduces the response to diuretic agents, which may offset any benefit from acute reductions in cardiac preload and afterload., (© 2023 The Authors.

Background: Women with heart failure with reduced ejection fraction (HFrEF) receive less guideline-recommended therapy and experience worse quality of life than men., Objectives: The authors sought to assess differences in baseline characteristics, outcomes, efficacy, and safety of omecamtiv mecarbil between men and women enrolled in the GALACTIC-HF (Registrational Study With Omecamtiv Mecarbil [AMG 423] to Treat Chronic Heart Failure With Reduced Ejection Fraction) study., Methods: In GALACTIC-HF, patients with symptomatic heart failure with EF of 35% or less, recent heart failure event, and elevated natriuretic peptides were randomized to omecamtiv mecarbil or placebo. The current analysis investigated differences in baseline characteristics, clinical outcomes, and efficacy and safety of omecamtiv mecarbil between men and women., Results: Of 8,232 patients analyzed, 21.2% were women. Women more likely self-identified as being Black, had worse symptoms (lower Kansas City Cardiomyopathy Questionnaire Total Symptom Score [KCCQ-TSS]), and were less likely to be treated with angiotensin receptor/neprilysin inhibitor and devices at baseline. Compared with men, women had lower rates of the primary endpoint (adjusted HR: 0.80, 95% CI: 0.73-0.88). Sex did not significantly modify omecamtiv mecarbil's treatment effect (P interaction = 0.68). Women also had 20% less risk of cardiovascular death, heart failure event, and all-cause death. Women participants had lower rates of serious adverse events., Conclusions: Women participants of the GALACTIC-HF trial had worse quality of life and were less likely to be treated with guideline-based therapies at baseline. Despite KCCQ-TSS being predictive of poor outcomes in this population, women had a 20% lower risk of an HF event or cardiovascular death compared with men. The beneficial effect of omecamtiv mecarbil did not significantly differ by sex.

Background: Polypharmacy is common among patients with heart failure with reduced ejection fraction (HFrEF). However, its impact on the use of optimal guideline-directed medical therapy (GDMT) is not well established., Objectives: This study sought to evaluate the association between polypharmacy and odds of receiving optimal GDMT over time among patients with HFrEF., Methods: The authors conducted a post hoc analysis of the GUIDE-IT (Guiding Evidence-Based Therapy Using Biomarker Intensified Treatment) trial. Polypharmacy was defined as receiving ≥5 medications (excluding HFrEF GDMT) at baseline. The outcome of interest was optimal triple therapy GDMT (concurrent administration of a renin-angiotensin-aldosterone blocker and beta-blocker at 50% of the target dose and a mineralocorticoid receptor antagonist at any dose) achieved over the 12-month follow-up. Multivariable adjusted mixed-effect logistic regression models with multiplicative interaction terms (time × polypharmacy) were constructed to evaluate how polypharmacy at baseline modified the odds of achieving optimal GDMT on follow-up., Results: The study included 891 participants with HFrEF. The median number of non-GDMT medications at baseline was 4 (IQR: 3-6), with 414 (46.5%) prescribed ≥5 and identified as being on polypharmacy. The proportion of participants who achieved optimal GDMT at the end of the 12-month follow-up was lower with vs without polypharmacy at baseline (15% vs 19%, respectively). In adjusted mixed models, the odds of achieving optimal GDMT over time were modified by baseline polypharmacy status (P for interaction < 0.001). Patients without polypharmacy at baseline had increased odds of achieving GDMT (OR: 1.16 [95% CI: 1.12-1.21] per 1-month increase; P < 0.001) but not patients with polypharmacy (OR: 1.01 [95% CI: 0.96-1.06)] per 1-month increase)., Conclusions: Patients with HFrEF who are on non-GDMT polypharmacy have lower odds of achieving optimal GDMT on follow-up., Competing Interests: Funding Support and Author Disclosures Dr Pandey has received research support from the National Institute on Aging GEMSSTAR grant (1R03AG067960-01) and the National Institute on Minority Health and Disparities (R01MD017529); grant funding from Applied Therapeutics and Gilead Sciences; honoraria outside of the present study as an advisor/consultant for Tricog Health Inc, Lilly USA, Rivus, Cytokinetics, and Roche Diagnostics; nonfinancial support from Pfizer and Merck; and is a consultant for Palomarin Inc with stock compensation.

Aims: Serial assessment of natriuretic peptides is widely utilized in heart failure clinics. Uncertainty exists regarding the value of multiple natriuretic peptide measurements and how they might be best interpreted., Methods and Results: Six hundred thirty-two patients with heart failure with reduced ejection fraction (<40%) and complete biomarker data were enrolled to receive sacubitril/valsartan. Patients underwent periodic study visits during 1-year follow-ups. Echocardiographic data and cardiac biomarkers, including N-terminal pro-B-type natriuretic peptide (NT-proBNP) were collected during study visits. Patients were categorized into three groups based on tertiles of baseline NT-proBNP levels. The area under the curve (AUC) of NT-proBNP measurements across study visits was calculated. Compared with patients with higher AUC (and thus higher concentrations over a longer period of time), those with lower AUC were younger, had a lower prevalence of chronic kidney disease, prior coronary artery bypass graft, atrial fibrillation, and higher body-mass index. A significant interaction existed between baseline NT-proBNP and subsequent AUC for predicting LVEF change across visits (P-value < 0.001): among those with lower baseline NT-proBNP, similar improvements in left ventricular (LV) volumes LV ejection fraction, and LV mass index were observed across subsequent AUC (P-value > 0.1). However, among those with higher baseline NT-proBNP, those with lower subsequent AUC had a greater improvement in cardiac remodelling indices (P-value < 0.05)., Conclusions: Serial NT-proBNP monitoring (integrating the totality of measurements as an AUC) during treatment with sacubitril/valsartan informs unique information regarding the future changes in cardiac remodelling indices, especially among those with higher NT-proBNP levels at baseline., (© 2023 The Authors.

Background: Continuous automatic optimisation of cardiac resynchronisation therapy (CRT), stimulating only the left ventricle to fuse with intrinsic right bundle conduction (synchronised left ventricular stimulation), might offer better outcomes than conventional CRT in patients with heart failure, left bundle branch block, and normal atrioventricular conduction. This study aimed to compare clinical outcomes of adaptive CRT versus conventional CRT in patients with heart failure with intact atrioventricular conduction and left bundle branch block., Methods: This global, prospective, randomised controlled trial was done in 227 hospitals in 27 countries across Asia, Australia, Europe, and North America. Eligible patients were aged 18 years or older with class 2-4 heart failure, an ejection fraction of 35% or less, left bundle branch block with QRS duration of 140 ms or more (male patients) or 130 ms or more (female patients), and a baseline PR interval 200 ms or less. Patients were randomly assigned (1:1) via block permutation to adaptive CRT (an algorithm providing synchronised left ventricular stimulation) or conventional biventricular CRT using a device programmer. All patients received device programming but were masked until procedures were completed. Site staff were not masked to group assignment. The primary outcome was a composite of all-cause death or intervention for heart failure decompensation and was assessed in the intention-to-treat population. Safety events were collected and reported in the intention-to-treat population. This study is registered with ClinicalTrials.gov, NCT02205359, and is closed to accrual., Findings: Between Aug 5, 2014, and Jan 31, 2019, of 3797 patients enrolled, 3617 (95·3%) were randomly assigned (1810 to adaptive CRT and 1807 to conventional CRT). The futility boundary was crossed at the third interim analysis on June 23, 2022, when the decision was made to stop the trial early. 1568 (43·4%) of 3617 patients were female and 2049 (56·6%) were male. Median follow-up was 59·0 months (IQR 45-72). A primary outcome event occurred in 430 of 1810 patients (Kaplan-Meier occurrence rate 23·5% [95% CI 21·3-25·5] at 60 months) in the adaptive CRT group and in 470 of 1807 patients (25·7% [23·5-27·8] at 60 months) in the conventional CRT group (hazard ratio 0·89, 95% CI 0·78-1·01; p=0·077). System-related adverse events were reported in 452 (25·0%) of 1810 patients in the adaptive CRT group and 440 (24·3%) of 1807 patients in the conventional CRT group., Interpretation: Compared with conventional CRT, adaptive CRT did not significantly reduce the incidence of all-cause death or intervention for heart failure decompensation in the included population of patients with heart failure, left bundle branch block, and intact AV conduction. Death and heart failure decompensation rates were low with both CRT therapies, suggesting a greater response to CRT occurred in this population than in patients in previous trials., Funding: Medtronic., Competing Interests: Declaration of interests BLW reports participating in physician advisory committees of Medtronic, Abbott, Boston Scientific, Biotronik, and Philips, and receiving honoraria from Medtronic, Abbott, Boston Scientific, Biotronik, Philips, and Cook.

Background: Electronic health record (EHR)-based identification of heart failure with preserved ejection fraction (HFpEF) in the clinical setting may facilitate screening for clinical trials by improving the understanding of its epidemiology and outcomes; yet, previous data have yielded variable results. We sought to characterize groups identified with HFpEF by different EHR screening strategies and their associated long-term outcomes across a large and diverse population., Methods: We retrospectively analyzed 116,499 consecutive patients from an academic referral center who underwent echocardiography, and 9,263 patients who underwent echocardiography within 6 months of right heart catheterization (RHC), between 2008 and 2018. EHR-based screening strategies identified patients with HFpEF using 1) International Classification of Diseases (ICD)-9/10 codes, 2) H 2 FpEF score ≥6 and ejection fraction (EF) ≥50%, or 3) RHC wedge pressure ≥15 mmHg and EF ≥50%, when available. Primary outcomes were 1) cumulative incident heart failure hospitalization (HFH), and 2) death, over 10 years., Results: There were 33,461 (29%) patients who met either ICD or H 2 FpEF-HFpEF definition, of whom 5,310 (16%) met both criteria. Compared to ICD-HFpEF, patients with H 2 FpEF-HFpEF were more likely older (median age 72 vs 67), White (78% vs 64%), and had atrial fibrillation (97% vs 41%). Among those also with RHC, 6,353 (69%) patients met any HFpEF criteria, of whom only 783 (12%) satisfied all three criteria. Female sex was more common among RHC-HFpEF (55%) compared to other methods (H 2 FpEF-HFpEF, 47%; ICD-HFpEF, 43%). Atrial fibrillation was substantially higher among HFpEF identified by the H 2 FpEF score (97%) compared to other methods (49% for ICD and 47% for RHC). Across HFpEF screening methods, 10-year cumulative incidence rates for HFH was 32% to 45% for echocardiography only and 43% to 52% for echocardiography and RHC populations; 10-year risk of death was 54% to 56% for echocardiography only and 52% to 57% for echocardiography and RHC populations., Conclusions: Different EHR-based HFpEF definitions identified cohorts with modest overlap and varying baseline characteristics. Yet, long-term risk for HFH and death were similarly high for cohorts identified among both populations undergoing echocardiography only or echocardiography and RHC. These data aid in identifying relevant subgroups in clinical trials of HFpEF., (Copyright © 2023. Published by Elsevier Inc.)

Aims: Heart failure (HF) guidelines recommend initiation and optimization of guideline-directed medical therapy, including mineralocorticoid receptor antagonists (MRAs), before hospital discharge. However, scientific evidence for this recommendation is lacking. Our objective was to determine whether initiation of MRA prior to hospital discharge is associated with improved outcomes., Methods and Results: We performed a secondary analysis of 6197 patients enrolled in the RELAX-AHF-2 study. Patients were divided into four groups according to MRA therapy at baseline and discharge. At baseline 30% of patients received MRA therapy, which increased to 50% of patients at discharge. In-hospital initiation of an MRA was observed in 1690 (27%) patients, 1438 (23%) patients remained on MRA therapy, 418 (7%) patients discontinued MRA treatment, and 2651 (43%) patients did not receive an MRA during hospital stay. Compared with patients who did not receive MRA therapy, in-hospital initiation of an MRA was independently associated with lower risks of mortality (multivariable hazard ratio [HR] 0.76, 95% confidence interval [CI] 0.60-0.96; p = 0.02), cardiovascular death (HR 0.77, 95% CI 0.59-1.01; p = 0.06), hospitalization for HF or renal failure (HR 0.72, 95% CI 0.60-0.86; p = 0.0003) and the composite endpoint of cardiovascular death and/or rehospitalization for HF or renal failure (HR 0.71, 95% CI 0.61-0.83; p < 0.0001) at 180 days. These results were independent of baseline left ventricular ejection fraction., Conclusion: In patients hospitalized for acute HF, in-hospital initiation of an MRA was associated with improved post-discharge outcomes, independent of left ventricular ejection fraction and other potential confounders., (© 2023 The Authors.

Aims: Adrenomedullin is a vasodilatory peptide with a role in microcirculatory and endothelial homeostasis. Adrenomedullin is a substrate for neprilysin and may therefore play a role in beneficial effects of sacubitril/valsartan (Sac/Val) treatment., Methods and Results: Mid-regional pro-adrenomedullin (MR-proADM) was measured in 156 patients with heart failure with reduced ejection fraction (HFrEF) treated with Sac/Val and 264 patients with heart failure with preserved ejection fraction (HFpEF) randomized to treatment with Sac/Val or valsartan. Echocardiography and Kansas City Cardiomyopathy Questionnaire results were collected at baseline and after 6 and 12 months in the HFrEF cohort. Median (Q1-Q3) baseline MR-proADM concentrations were 0.80 (0.59-0.99) nmol/L in HFrEF and 0.88 (0.68-1.20) nmol/L in HFpEF. After 12 weeks of treatment with Sac/Val, MR-proADM increased by median 49% in HFrEF and 60% in HFpEF, while there were no significant changes in valsartan-treated patients (median 2%). Greater increases in MR-proADM were associated with higher Sac/Val doses. Changes in MR-proADM correlated weakly with changes in N-terminal pro-B-type natriuretic peptide, cardiac troponin T and urinary cyclic guanosine monophosphate. Increases in MR-proADM were associated with decreases in blood pressure, but not significantly associated with changes in echocardiographic parameters or health status., Conclusions: MR-proAD concentrations rise substantially following treatment with Sac/Val, in contrast to no change from valsartan. Change in MR-proADM from neprilysin inhibition did not correlate with improvements in cardiac structure and function or health status. More data are needed regarding the role of adrenomedullin and its related peptides in the treatment of heart failure., Clinical Trial Registration: PROVE-HF ClinicalTrials.gov Identifier: NCT02887183, PARAMOUNT ClinicalTrials.gov Identifier: NCT00887588., (© 2023 The Authors.

Background: Hospitalization due to heart failure (HFH) is a major source of morbidity, consumes significant economic resources and is a key endpoint in HF clinical trials. HFH events vary in severity and implications, but they are typically considered equivalent when analyzing clinical trial outcomes., Objectives: We aimed to evaluate the frequency and severity of HF events, assess treatment effects and describe differences in outcomes by type of HF event in VICTORIA (Vericiguat Global Study in Subjects with Heart Failure with Reduced Ejection Fraction)., Methods: VICTORIA compared vericiguat with placebo in patients with HF with reduced ejection fraction (< 45%) and a recent worsening HF event. All HFHs were prospectively adjudicated by an independent clinical events committee (CEC) whose members were blinded to treatment assignment. We evaluated the frequency and clinical impact of HF events by severity, categorized by highest intensity of HF treatment (urgent outpatient visit or hospitalization treated with oral diuretics, intravenous diuretics, intravenous vasodilators, intravenous inotropes, or mechanical support) and treatment effect by event categories., Results: In VICTORIA, 2948 HF events occurred in 5050 enrolled patients. Overall total CEC HF events for vericiguat vs placebo were 43.9 vs 49.1 events/100 patient-years (P = 0.01). Hospitalization for intravenous diuretics was the most common type of HFH event (54%). HF event types differed markedly in their clinical implications for both in-hospital and post-discharge events. We observed no difference in the distribution of HF events between randomized treatment groups (P = 0.78)., Conclusion: HF events in large global trials vary significantly in severity and clinical implications, which may have implications for more nuanced trial design and interpretation., Clinical Trial Registration: ClinicalTrials.gov (NCT02861534)., (Copyright © 2023 Elsevier Inc.

Background: We aimed to study whether improvement in renal function by serelaxin in patients who were hospitalized for acute heart failure (HF) might explain any potential effect on clinical outcomes., Methods: We included 6318 patients from the RELAXin in AHF-2 (RELAX-AHF2) study. Improvement in renal function was defined as a decrease in serum creatinine of ≥ 0.3 mg/dL and ≥ 25%, or increase in estimated glomerular filtration rate of ≥ 25% between baseline and day 2. Worsening renal function (WRF) was defined as the reverse. We performed causal mediation analyses regarding 180-day all-cause mortality (ACM), cardiovascular death (CVD), and hospitalization for HF/renal failure., Results: Improvement in renal function was more frequently observed with serelaxin when compared with placebo [OR 1.88 (95% CI 1.64-2.15, p < 0.0001)], but was not associated with subsequent clinical outcomes. WRF occurred less frequent with serelaxin [OR 0.70 (95% CI 0.60-0.83, p < 0.0001)] and was associated with increased risk of ACM, worsening HF and the composite of CVD and HF or renal failure hospitalization. Improvement in renal function did not mediate the treatment effect of serelaxin [CVD HR 1.01 (0.99-1.04), ACM HR 1.01 (0.99-1.03), HF/renal failure hospitalization HR 0.99 (0.97-1.00)]., Conclusions: Despite the significant improvement in renal function by serelaxin in patients with acute HF, the potential beneficial treatment effect was not mediated by improvement in renal function. These data suggest that improvement in renal function might not be a suitable surrogate marker for potential treatment efficacy in future studies with novel relaxin agents in acute HF.

Background: We sought to determine whether circulating modifiers of endothelial function are associated with cardiac structure and clinical outcomes in patients with heart failure with reduced ejection fraction (HFrEF)., Methods: We measured 25 proteins related to endothelial function in 99 patients from the GUIDE-IT study. Protein levels were evaluated for association with echocardiographic parameters and the incidence of all-cause death and hospitalization for heart failure (HHF)., Results: Higher concentrations of angiopoietin 2 (ANGPT2), vascular endothelial growth factor receptor 1 (VEGFR1) and hepatocyte growth factor (HGF) were significantly associated with worse function and larger ventricular volumes. Over time, decreases in ANGPT2 and, to a lesser extent, VEGFR1 and HGF, were associated with improvements in cardiac size and function. Individuals with higher concentrations of ANGPT2, VEGFR1 or HGF had increased risks for a composite of death and HHF in the following year (HR 2.76 (95% CI 1.73-4.40) per 2-fold change in ANGPT2; HR 1.76 (95% CI 1.11-2.79) for VEGFR1; and HR 4.04 (95% CI 2.19-7.44) for HGF)., Conclusions: Proteins related to endothelial function associate with cardiac size, cardiac function and clinical outcomes in patients with HFrEF. These results support the concept that endothelial function may be an important contributor to the progression to and the recovery from HFrEF., (Copyright © 2023 Elsevier Inc. All rights reserved.)

Aims: Severe tricuspid regurgitation (TR) exhibits high 1-year morbidity and mortality, yet long-term cardiovascular risk overall and by subgroups remains unknown. This study characterizes 5-year outcomes and identifies distinct clinical risk profiles of severe TR., Methods and Results: Patients were included from a large US tertiary referral center with new severe TR by echocardiography based on four-category American Society of Echocardiography grading scale between 2007 and 2018. Patients were categorized by TR etiology (with lead present, primary, and secondary) and by supervised recursive partitioning (survival trees) for outcomes of death and the composite of death or heart failure hospitalization. The Kaplan-Meier estimates and Cox regression models were used to evaluate any association by (i) TR etiology and (ii) groups identified by survival trees and outcomes over 5 years. Among 2379 consecutive patients with new severe TR, median age was 70 years, 61% were female, and 40% were black. Event rates (95% confidence interval) were 30.9 (29.0-32.8) events/100 patient-years for death and 49.0 (45.9-52.2) events/100 patient-years for the composite endpoint, with no significant difference by TR etiology. After applying supervised survival tree modeling, two separate groups of four phenoclusters with distinct clinical prognoses were separately identified for death and the composite endpoint. Variables discriminating both outcomes were age, albumin, blood urea nitrogen, right ventricular function, and systolic blood pressure (all P < 0.05)., Conclusion: Patients with newly identified severe TR have high 5-year risk for death and death or heart failure hospitalization. Partitioning patients using supervised survival tree models, but not TR etiology, discriminated clinical risk. These data aid in identifying relevant subgroups in clinical trials of TR and clinical risk/benefit analysis for TR therapies., Competing Interests: Conflict of interest V.N.R.: salary support from a National Institutes of Health T32 training grant.

Background Many patients with heart failure (HF) have severely reduced ejection fraction but do not meet threshold for consideration of advanced therapies (ie, stage D HF). The clinical profile and health care costs associated with these patients in US practice is not well described. Methods and Results We examined patients hospitalized for worsening chronic heart failure with reduced ejection fraction ≤40% from 2014 to 2019 in the GWTG-HF (Get With The Guidelines-Heart Failure) registry, who did not receive advanced HF therapies or have end-stage kidney disease. Patients with severely reduced EF defined as EF ≤30% were compared with those with EF 31% to 40% in terms of clinical profile and guideline-directed medical therapy. Among Medicare beneficiaries, postdischarge outcomes and health care expenditure were compared. Among 113 348 patients with EF ≤40%, 69% (78 589) had an EF ≤30%. Patients with severely reduced EF ≤30% tended to be younger and were more likely to be Black. Patients with EF ≤30% also tended to have fewer comorbidities and were more likely to be prescribed guideline-directed medical therapy ("triple therapy" 28.3% versus 18.2%, P <0.001). At 12-months postdischarge, patients with EF ≤30% had significantly higher risk of death (HR, 1.13 [95% CI, 1.08-1.18]) and HF hospitalization (HR, 1.14 [95% CI, 1.09-1.19]), with similar risk of all-cause hospitalizations. Health care expenditures were numerically higher for patients with EF ≤30% (median US$22 648 versus $21 392, P =0.11). Conclusions Among patients hospitalized for worsening chronic heart failure with reduced ejection fraction in US clinical practice, most patients have severely reduced EF ≤30%. Despite younger age and modestly higher use of guideline-directed medical therapy at discharge, patients with severely reduced EF face heightened postdischarge risk of death and HF hospitalization.

Natriuretic peptides, brain (B-type) natriuretic peptide (BNP) and N-terminal prohormone of brain natriuretic peptide (NT-proBNP) are globally and most often used for the diagnosis of heart failure (HF). In addition, they can have an important complementary role in the risk stratification of its prognosis. Since the development of angiotensin receptor neprilysin inhibitors (ARNIs), the use of natriuretic peptides as therapeutic agents has grown in importance. The present document is the result of the Trilateral Cooperation Project among the Heart Failure Association of the European Society of Cardiology, the Heart Failure Society of America and the Japanese Heart Failure Society. It represents an expert consensus that aims to provide a comprehensive, up-to-date perspective on natriuretic peptides in the diagnosis and management of HF, with a focus on the following main issues: (1) history and basic research: discovery, production and cardiovascular protection; (2) diagnostic and prognostic biomarkers: acute HF, chronic HF, inclusion/endpoint in clinical trials, and natriuretic peptides-guided therapy; (3) therapeutic use: nesiritide (BNP), carperitide (ANP) and ARNIs; and (4) gaps in knowledge and future directions., Competing Interests: Disclosures HT receives consultancy fees from Boehringer Ingelheim, Bayer Yakuhin, Novartis Pharma, Ono Pharmaceutical, Astra-Zeneca; remuneration from MSD, Astellas Pharma, Pfizer Japan, Bristol-Myers Squibb Company, Otsuka Pharmaceutical, Daiichi Sankyo, Mitsubishi Tanabe Pharma, Boehringer Ingelheim, Takeda Pharmaceutical, Bayer Yakuhin, Novartis Pharma, Kowa Pharmaceutical, Teijin Pharma; manuscript fees from Medical View, Nippon Rinsho; research funding from Actelion Pharmaceuticals Japan, Japan Tobacco, Mitsubishi Tanabe Pharma Nippon Boehringer Ingelheim, Daiichi Sankyo, IQVIA Services Japan, Omron Healthcare; scholarship funds from Astellas Pharma, Novartis Pharma, Daiichi Sankyo, Takeda Pharmaceutical, Mitsubishi Tanabe Pharma, Teijin Pharma, MSD.

Background: Heart failure (HF) guidelines recommend assessment of left ventricular ejection fraction (LVEF) to classify patients and guide therapy implementation. However, LVEF alone may be insufficient to adequately characterize patients with HF, especially those with mildly reduced or preserved LVEF. Recommendations on additional testing are lacking, and there are limited data on use of echocardiographic features beyond LVEF in patients with heart failure with mildly reduced or preserved LVEF., Methods: In patients with HF with mildly reduced or preserved LVEF identified in a large US health care system, the association of the following metrics with mortality was evaluated: LV global longitudinal strain (LV GLS>-16), left atrial volume index (>28 mL/m 2 ), left ventricular hypertrophy (LVH), and E/e´>13 and e´<9. A multivariable model for mortality was constructed including age, sex, and key comorbidities followed by stepwise selection of echocardiographic features. Characteristics and outcomes of subgroups with normal versus abnormal LV GLS and LVEF were evaluated., Results: Among 2337 patients with complete echocardiographic data assessed between 2017 and 2020, the following features were associated with all-cause mortality on univariate analysis over 3 years of follow-up: E/e´+e´, LV GLS, left atrial volume index (all P <0.01). In the multivariable model ( C -index=0.65), only abnormal LV GLS was independently associated with all-cause mortality (HR, 1.35 [95% CI, 1.11-1.63]; P =0.002). Among patients with LVEF>55%, 498/1255 (40%) demonstrated abnormal LV GLS. Regardless of specific LVEF, patients with abnormal LV GLS demonstrated a higher burden of multiple comorbidities and higher event rates compared with patients with normal LV GLS., Conclusions: In a large, real-world HF with mildly reduced or preserved LVEF population, echocardiographic features, led by LV GLS, were associated with adverse outcomes irrespective of LVEF. A large proportion of patients demonstrate adverse myocardial function by LV GLS despite preserved LVEF and may represent a key cohort of interest for HF medical therapies and future clinical studies., Competing Interests: Disclosures Dr Peters is supported by the National Heart, Lung, and Blood Institute (NHLBI; T32HL069749) and has received honoraria from Cytokinetics.

Although the prevalence of HF in young adults (age <50 years) is increasing, there are limited data on the trajectory of decongestion and short-term outcomes in young adults with acute heart failure (AHF). We pooled patients from 3 randomized trials of AHF conducted within the Heart Failure Network (the Diuretic Optimization Strategies trial, the Renal Optimization Strategies Trial, and the Cardiorenal Rescue Study in Acute Decompensated Heart Failure). The association between young age (<50 years and >50 years) and in-hospital changes in various measures of decongestion as well as short-term outcomes including risk for rehospitalization, and all-cause mortality was evaluated. Of 762 patients, 72 (10.3%) patients were young. Young adults were more likely to be African American (53.8% vs 19.3%), to have a lower rate of ischemic HF etiology (25.6% vs 60.4%, P <0.001), and a lower burden of hypertension, chronic kidney disease and atrial fibrillation. Young adults had a lower left ventricular ejection fraction (median 20% vs 33%, P < 0.001); they had a higher admission weight (median 242.7 lbs vs 201.5 lbs, P < 0.001), but lower NT-pro BNP levels (median 3622 pg/mL vs 4676 pg/mL, P = 0.003). After covariate adjustment, there was no difference in the change in NT-pro BNP (P = 0.25), net fluid loss (P = 0.42), or renal function (P = 0.56) between young and older adults by 72 or 96 hours of randomization. There was no difference in orthodema congestion score or the composite clinical endpoint during the follow-up (all-cause mortality or any rehospitalization) (adjusted odds ratios (95% confidence intervals): 2.51 (0.78-8.01), P = 0.12). In this pooled analysis of 3 clinical trial cohorts, compared with older adults, younger adults had a unique demographic and clinical profile. Despite these differences, there was no difference by age group in in-hospital decongestion or post-discharge readmission or mortality., (Copyright © 2022 Elsevier Inc. All rights reserved.)

Background: Initiation and up-titration of guideline-directed medical therapies (GDMTs) for heart failure with reduced ejection fraction (HFrEF) remains suboptimal, in part because of concerns regarding tolerability and adverse events (AEs)., Objectives: The authors sought to compare rates of AE in patients randomized to GDMT medication vs placebo in a meta-analysis of landmark cardiovascular outcomes trials., Methods: The authors assessed rates of reported AE in 17 landmark HFrEF clinical trials across each class of GDMT in the placebo and intervention arms. The overall rates of AE for each drug class, the absolute difference in frequency in AEs between the placebo and intervention arms, and the odds of each AE according based on randomization strata were calculated., Results: AE were reported commonly in trials across each class of GDMT, with 75% to 85% of participants reporting at least 1 AE. There was no significant difference in the frequency of AE between the intervention and placebo arms, except for angiotensin-converting enzyme inhibitors (87.0% [95% CI: 85.0%-88.8%] vs 82.0% [95% CI: 79.8%-84.0%], absolute difference: +5% with intervention; P < 0.001). There was no significant difference in drug discontinuation because of AE between placebo and intervention arms in angiotensin-converting enzyme inhibitors, mineralocorticoid receptor antagonists, sodium glucose cotransporter 2 inhibitors, or angiotensin receptor neprilysin inhibitor/angiotensin II receptor blocker trials. Patients randomized to beta-blocker were significantly less likely to stop study drug because of AE than placebo (11.3% [95% CI: 10.3%-12.3%] vs 13.7% [95% CI: 12.5%-14.9%], absolute difference: -1.1%; P = 0.015). When individual types of AE were assessed, the initiation of an intervention vs placebo resulted in small differences in absolute frequency of AE that were largely not statistically significant., Conclusions: In clinical trials of GDMT for HFrEF, AEs are observed frequently. However, rates of AE are similar between active medication and control, suggesting these may reflect the high risk nature of the heart failure disease state rather than be attributive to a specific therapy., Competing Interests: Funding Support and Author Disclosures Dr Harrington has received salary support from T32 training grant T32HL069749.

Aims: The impact of mitral regurgitation (MR) in patients hospitalized for acute heart failure (AHF) is not well established. We assessed the role of MR in patients enrolled in the Relaxin in Acute Heart Failure 2 (RELAX-AHF-2) trial., Methods and Results: Patients enrolled in RELAX-AHF-2 with available data regarding MR status were included in this analysis. Baseline characteristics, in-hospital data, and clinical outcomes through 180-day follow-up were evaluated. The impact of moderate/severe MR was assessed. Among 6420 AHF patients with known MR status, 1810 patients (28.2%) had moderate/severe MR. Compared to patients with no/mild MR, those with moderate/severe MR were more likely to have history of heart failure (HF), prior HF hospitalization, more comorbidities, symptoms/signs of HF, lower left ventricular ejection fraction and higher N-terminal pro-B-type natriuretic peptide levels. Moderate/severe MR was associated with longer length of hospital stay, higher rates of residual dyspnoea, increased jugular venous pressure through the index hospitalization and a higher unadjusted risk of the composite of cardiovascular (CV) death or rehospitalization for HF/renal failure (RF) through 180 days (crude hazard ratio [HR] 1.15, 95% confidence interval [CI] 1.03-1.27, p = 0.01). The association between moderate/severe MR and poorer outcomes was not maintained in a multivariable model including several covariates of interest (adjusted HR 1.03, 95% CI 0.91-1.17, p = 0.65). Similar findings were observed for HF/RF rehospitalization alone., Conclusions: In patients with AHF, moderate/severe MR was associated with a worse clinical profile but did not have an independent prognostic impact on clinical outcomes., (© 2023 The Authors.

Aim: N-terminal pro-B-type natriuretic peptide (NT-proBNP) is predictive of both outcomes and response to treatment in patients with heart failure with reduced ejection fraction (HFrEF). The aim of this study was to examine the effect of the cardiac myosin activator omecamtiv mecarbil according to baseline NT-proBNP level in the Global Approach to Lowering Adverse Cardiac outcomes Through Improving Contractility in Heart Failure trial (GALACTIC-HF)., Methods and Results: The primary outcome was the composite of a worsening heart failure event (urgent clinic visit, emergency department visit, or hospitalization) or cardiovascular death. We prespecified analysis of the effect of treatment according to baseline NT-proBNP (≤ median, > median), excluding individuals with atrial fibrillation/flutter (AF/AFL). Of the 8232 patients analysed, 8206 had an available baseline NT-proBNP measurement. Among the 5971 patients not in AF/AFL, the median (Q1-Q3) NT-proBNP level was 1675 (812-3579) pg/ml. Hazard ratios (HR) for the effect of omecamtiv mecarbil, compared with placebo, for the primary endpoint in patients without AF/AFL were: ≤ median 0.94 (95% confidence interval [CI] 0.80-1.09), > median 0.81 (0.73-0.90) (p-interaction = 0.095); for the overall population (including patients with AF/AFL) the HRs were ≤ median 1.01 (0.90-1.15) and > median 0.88 (0.80-0.96) (p-interaction = 0.035). There was an interaction between treatment and NT-proBNP, examined as a continuous variable, with greater effect of omecamtiv mecarbil on the primary outcome in patients with a higher baseline NT-proBNP (p-interaction = 0.086)., Conclusions: In GALACTIC-HF, the benefit of omecamtiv mecarbil appeared to be larger in patients with higher baseline NT-proBNP levels, especially in patients without AF/AFL., Clinical Trial Registration: ClinicalTrials.gov Identifier NCT02929329; EudraCT number, 2016-002299-28., (© 2023 The Authors.
