Five-year mortality of heart failure with preserved, mildly reduced, and reduced ejection fraction in a 4880 Chinese cohort.

ABSTRACT:

Aims

Available evidence is incomplete and inconsistent in the outcomes of heart failure (HF) patients with preserved ejection fraction (HFpEF), mildly reduced ejection fraction (HFmrEF), and reduced ejection fraction (HFrEF). There are also limited data on the proportions and long-term prognosis among the three HF phenotypes in China. We aimed to characterize the 5 year prognosis in three HF phenotypes according to EF in a cohort of hospitalized HF patients undergoing coronary angiography in southern China.

Methods and results

Hospitalized patients with HF were enrolled from the Cardiorenal ImprovemeNt registry (CIN; ClinicalTrials.gov NCT04407936) between January 2007 and December 2014. HF phenotypes were defined as HFpEF (EF ≥ 50%), HFmrEF (EF 41-49%), and HFrEF (EF ≤ 40%). Kaplan-Meier and Cox proportional hazards models were constructed to examine differences in 5 year outcomes in HF patients with different phenotypes. A total of 4880 HF patients [mean age: 61.8 ± 10.3, male: 3156 (64.7%)] were included: 2768 (57%) had HFpEF, 1015 (21%) had HFmrEF, and 1097 (22%) had HFrEF. Patients with HFrEF were older than those with HFpEF (62.5 ± 10.6 vs. 61.3 ± 10.1, P < 0.001) and more likely to be male (78.0% vs. 55.9%, P < 0.001). With 5 year follow-up through the end of December 2019, 1624 (27.6%) patients died. Controlling confounding variables, declined EF category was independently associated with increased 5 year mortality {HFrEF 25.2% vs. HFpEF 13.4%, adjusted hazard ratio [aHR]: 1.85 [95% confidence interval (CI): 1.45 to 2.35]; HFmrEF 18.1% vs. HFpEF 13.4%, aHR: 1.40 [95% CI: 1.08 to 1.81]; HFrEF 25.2% vs. HFmrEF 18.1%, aHR: 1.32 [95% CI: 1.02 to 1.71]}.

Conclusions

In this Chinese cohort, patients with HFrEF account for less than a fourth of HF patients. One-sixth individuals with HF died in 5 years. HFrEF was associated with a nearly two-fold increased risk of 5 year mortality than HFpEF. Further studies are needed to prospectively evaluate the efficacy of improving treatment on outcomes in all three HF phenotypes.

Project description:BackgroundMany therapies for heart failure (HF) have shown differential impact across the spectrum of left ventricular ejection fraction (LVEF).ObjectivesIn this prespecified analysis, the authors assessed the effects of semaglutide across the baseline LVEF strata in patients with the obesity phenotype of HF with preserved ejection fraction (HFpEF) in the STEP-HFpEF (Semaglutide Treatment Effect in People with obesity and HFpEF) trial.MethodsSTEP-HFpEF randomized 529 patients (263 semaglutide; 266 placebo). For this prespecified analysis, patients were categorized into 3 groups based on LVEF: 45% to 49% (n = 85), 50% to 59% (n = 215), and ≥60% (n = 229).ResultsAt 52 weeks, semaglutide improved the dual primary endpoints of Kansas City Cardiomyopathy Questionnaire Clinical Summary Score (estimated treatment difference: EF [ejection fraction] 45%-49%: 5.0 points [95% CI: -2.7 to 12.8 points], EF 50%-59%: 9.8 points [95% CI: 5.0 to 14.6 points], and EF ≥60%: 7.4 points [95% CI: 2.8 to 12.0 points]; P interaction = 0.56) and body weight (EF: 45%-49%: -7.6 [95% CI: -10.7 to -4.4], EF 50%-59%: -10.6 [95% CI: -12.6 to -8.6] and EF ≥60%: -11.9 [95% CI: -13.8 to -9.9]; P interaction = 0.08), to a similar extent across LVEF categories. Likewise, LVEF did not influence the benefit of semaglutide on confirmatory secondary endpoints: 6-minute walk distance (P interaction = 0.19), hierarchal composite endpoint (P interaction = 0.43), and high-sensitivity C-reactive protein (P interaction = 0.26); or exploratory endpoint of N-terminal pro-brain natriuretic peptide (P interaction = 0.96). Semaglutide was well-tolerated across LVEF categories.ConclusionsIn patients with HFpEF and obesity, semaglutide 2.4 mg improved symptoms, physical limitations, and exercise function, and reduced inflammation and body weight to a similar extent across LVEF categories. These data support treatment with semaglutide in patients with the obesity phenotype of HFpEF regardless of LVEF.

Project description:AimsEmpagliflozin, a sodium-glucose co-transporter 2 inhibitor, was shown to be effective in patients with heart failure with preserved ejection fraction (HFpEF) in the EMPEROR-Preserved trial. The present study aims to evaluate the cost-effectiveness of empagliflozin among Japanese patients with HFpEF.Methods and resultsA Markov cohort model was developed to evaluate the cost-effectiveness of empagliflozin added to standard of care (SoC) compared with SoC alone in patients with HFpEF from the perspective of the Japanese healthcare system and with a lifetime horizon. In addition to clinical events, the progression of disease severity was modelled based on the migration of Kansas City Cardiomyopathy Questionnaire-Clinical Summary Scores (KCCQ-CSS). Model inputs, including risk of clinical events, costs, and utilities/disutilities, were derived from EMPEROR-Preserved trial data, a claims database and published literature. The generalizability of model results was investigated by applying various subgroups including age, body mass index (BMI), and region Asia, based on the subgroup analysis of EMPEROR-Preserved data. In the base-case analysis, empagliflozin yielded additional quality-adjusted life years (QALYs; 0.11) with an incremental cost of $1408 per patient for Japanese patients with HFpEF. Incremental cost, mainly derived from drug acquisition cost ($1963 per patient), was largely offset by reduced cost in hospitalization for heart failure (HHF) and cardiovascular death (-$537 per patient and -$166 per patient, respectively). Treatment of empagliflozin provided incremental 0.11 QALYs and 0.08 life years compared with SoC alone. The incremental cost-effectiveness ratio (ICER) was $12 772 (¥1 662 689)/QALY, which was below the Japanese willingness-to-pay (WTP) threshold of $38 408 (¥5 000 000)/QALY. The results were consistent across all the subgroups considered, and empagliflozin was dominant over SoC alone in the region Asia and BMI < 25 kg/m2 subgroups. ICERs for the remaining subgroups ranged from $7520/QALY (¥978 972/QALY, patients with baseline age ≥ 75 years) to $31 049/QALY (¥4 041 896/QALY, patients with baseline New York Heart Association class III/IV). Deterministic sensitivity analysis result showed that the treatment effect on HHF is the biggest driver of the cost-effectiveness analysis, while the ICER will be still under the threshold even if no effect of empagliflozin on HHF was assumed. The probabilistic sensitivity analysis result showed that 64% of simulations were cost-effective based on the Japanese WTP threshold.ConclusionsEmpagliflozin was demonstrated to be cost-effective for patients with HFpEF in Japan based on EMPEROR-Preserved trial data.

Project description:ImportanceIn recent years, significant progress has been made in the pharmacologic treatment of heart failure (HF) with reduced ejection fraction (HFrEF), but there is still insufficient evidence for drug therapy for HF with preserved ejection fraction (HFpEF) and mildly reduced ejection fraction (HFmrEF).ObjectiveTo compare the outcomes associated with different drug combinations for the treatment of HFpEF and HFmrEF.Data sourcesA search of the PubMed, Embase, and Cochrane Central Register of Controlled Trials (CENTRAL) databases was conducted for studies published from inception to October 9, 2021.Study selectionRandomized clinical trials on the use of angiotensin-converting enzyme (ACE) inhibitors, angiotensin receptor blockers (ARBs), angiotensin receptor-neprilysin inhibitors (ARNIs), mineralocorticoid receptor antagonists (MRAs), β-blockers, and sodium-glucose cotransporter 2 (SGLT2) inhibitors for patients with HFpEF or HFmrEF.Data extraction and synthesisData extraction and bias assessment were independently performed by 2 reviewers following the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guideline. All data for 3 outcomes were pooled with a fixed-effect model.Main outcomes and measuresThe main outcomes were first hospitalization for HF, all-cause mortality, and cardiovascular mortality. Hazard ratios (HRs) and 95% credible intervals (CrIs) were evaluated using a bayesian network meta-analysis model.ResultsIn this analysis, 19 randomized clinical trials, including 20 633 patients with HF and an ejection fraction of 40% or more, without a remarkable risk of bias were included. Compared with placebo, no treatments were associated with a significant reduction in the risk of all-cause death or cardiovascular death. SGLT2 inhibitors, ARNIs, and MRAs were associated with a significant decrease in the risk of HF hospitalization compared with placebo (SGLT2 inhibitors: HR, 0.71 [95% CrI, 0.60-0.83]; ARNIs: HR, 0.76 [95% CrI, 0.61-0.95]; MRAs: HR, 0.83 [95% CrI, 0.69-0.99]), and SGLT2 inhibitors were the optimal drug class in terms of reducing the risk for HF admission. Sensitivity analysis results demonstrated a progressive decrease in the risk of HF admission and an advance in mean rank associated with the increasing use of drug classes.Conclusions and relevanceThe findings of this study suggest that SGLT2 inhibitors were the optimal drug class for HFpEF and HFmrEF, consistent with the most recent guideline recommendation. The incremental use of combinations of SGLT2 inhibitors, ACE inhibitors or ARBs, and β-blockers may be associated with accumulative benefits in HF hospitalization rather than all-cause death among patients with HFpEF and HFmrEF.

Project description:AimsClinical trials in heart failure with mildly reduced or preserved ejection fraction (HFmrEF/HFpEF) commonly have detailed eligibility criteria. This may contribute to challenges with efficient enrolment and questions regarding the generalizability of trial findings.Methods and resultsPatients with HFmrEF/HFpEF from a large US healthcare system were identified through a computable phenotype applied in linked imaging and electronic health record databases. We evaluated shared eligibility criteria from five recent/ongoing HFmrEF/HFpEF trials (PARAGON-HF, EMPEROR-Preserved, DELIVER, FINE-ARTS, and SPIRRIT-HFpEF) and compared clinical and echocardiographic features as well as outcomes between trial-eligible and trial-ineligible patients. Among 5552 patients with HFpEF/HFmrEF, 792 (14%) were eligible for trial consideration, having met all criteria assessed. Causes of ineligibility included lack of recent loop diuretics (37%), significant pulmonary disease (24%), reduced estimated glomerular filtration rate (17%), recent stroke/transient ischaemic attack (13%), or low natriuretic peptides (12%); 53% of ineligible patients had >1 reason for exclusion. Compared with eligible patients, ineligible patients were younger (age 71 vs. 75 years, P < 0.001) with higher rates of coronary artery disease (66% vs. 59%, P < 0.001) and peripheral vascular disease (40% vs. 33%, P < 0.001), but less mitral regurgitation, lower E/e' ratio, and smaller left atrial sizes. Both eligible and ineligible patients demonstrated high rates of structural heart disease consistent with HFpEF [elevated left atrial size or left ventricular (LV) hypertrophy/increased LV mass], although this was slightly higher among eligible patients (95% vs. 92%, P = 0.001). The two cohorts demonstrated similar LV global longitudinal strain along with a similar prevalence of atrial fibrillation/flutter, hypertension, and obesity. Ineligible patients had similar all-cause mortality (33% vs. 33% at 3 years) to those eligible but lower rates of heart failure hospitalization (20% vs. 28% at 3 years, P < 0.001).ConclusionsAmong patients with HFmrEF/HFpEF from a large health system, approximately one in seven were eligible for major trials based on key criteria applied through a clinical computable phenotype. These findings highlight the large proportion of patients with HFmrEF/HFpEF ineligible for contemporary trials for whom the generalizability of trial findings may be questioned and further investigation would be beneficial.

Project description:ImportanceTreatment with finerenone, a nonsteroidal mineralocorticoid receptor antagonist (MRA), improved outcomes in patients with heart failure with mildly reduced or preserved ejection fraction in FINEARTS-HF, but was associated with increased levels of serum potassium in follow-up.ObjectiveTo investigate the frequency and predictors of serum potassium level greater than 5.5 mmol/L and less than 3.5 mmol/L and examine the treatment effect associated with finerenone, relative to placebo, on clinical outcomes based on postrandomization potassium levels.Design, setting, and participantsSecondary analysis of the FINEARTS-HF multicenter, randomized clinical trial, performed between September 14, 2020, and January 10, 2023, with a median follow-up of 32 months (final date of follow-up: June 14, 2024). Patients with heart failure and left ventricular ejection fraction greater than or equal to 40%, New York Heart Association class II to IV symptoms, and elevated natriuretic peptides were included.InterventionParticipants received finerenone or placebo.Main outcomes and measuresThe primary outcome was a composite of total worsening heart failure events or cardiovascular death.ResultsA total of 6001 participants were included (3003 randomized to receive finerenone and 2998 randomized to receive placebo). The increase in serum potassium was greater in the finerenone group than the placebo group at 1 month (median [IQR] difference, 0.19 [0.17-0.21] mmol/L) and 3 months (median [IQR] difference, 0.23 [0.21-0.25] mmol/L), which persisted for the remainder of trial follow-up. Finerenone increased the risks of potassium level increasing to greater than 5.5 mmol/L (hazard ratio [HR], 2.16 [95% CI, 1.83-2.56]; P < .001) and decreased the risks for potassium level decreasing to less than 3.5 mmol/L (HR, 0.46 [95% CI, 0.38-0.56]; P < .001). Both low (< 3.5 mmol/L; HR, 2.49 [95% CI, 1.8-3.43]) and high (>5.5 mmol/L; HR, 1.64 [95% CI, 1.04-2.58]) potassium levels were associated with higher subsequent risks of the primary outcome in both treatment groups. Nevertheless, the risk of the primary outcome was generally lower in patients treated with finerenone compared with placebo, even in those whose potassium level increased to greater than 5.5 mmol/L.Conclusions and relevanceIn patients with heart failure with mildly reduced or preserved ejection fraction, finerenone resulted in more frequent hyperkalemia and less frequent hypokalemia. However, with protocol-directed surveillance and dose adjustment, clinical benefit associated with finerenone relative to placebo was maintained even in those whose potassium level increased to greater than 5.5 mmol/L.Trial registrationClinicalTrials.gov Identifier: NCT04435626.

Project description:AimsHeart failure with mildly reduced ejection fraction (HFmrEF) is associated with a favourable prognosis compared with heart failure (HF) with reduced ejection fraction (EF). We assessed whether left ventricular ejection fraction (LVEF) trajectory can be used to identify groups of patients with HFmrEF who have different clinical outcomes in a large retrospective study of patients with serial imaging.Methods and resultsPatients with HF and ≥2 echocardiograms performed ≥6 months apart were included if the LVEF measured 40-49% on the second study. Patients were classified as HFmrEF-Increasing if LVEF had increased ≥10% (n = 450), HFmrEF-Decreasing if LVEF had decreased ≥10% (n = 512), or HFmrEF-Stable if they did not meet other criteria (n = 389). The primary outcome was all-cause mortality or cardiovascular hospitalization after the second echocardiogram. Associations with time to first event were assessed with multivariable Cox analyses adjusted for age, co-morbidities, and medications. In total, 1351 patients with HFmrEF (median age 74, 64.2% male) were included with 28.8% exhibiting stable LVEF. During median follow-up of 15.3 months, the composite outcome occurred in 811 patients. During follow-up, patients with HFmrEF-Increasing were less likely to experience the primary outcome [adjusted hazard ratio (HR) 0.72, 95% confidence interval (CI) 0.60-0.88, P < 0.001] compared with HFmrEF-Stable. Patients with HFmrEF-Decreasing were more likely to experience the composite outcome in unadjusted analyses (unadjusted HR 1.19, 95% CI 1.01-1.40, P = 0.040) but not adjusted analyses (adjusted HR 1.16, 95% CI 0.98-1.37, P = 0.092). Associations with death or HF hospitalizations were similar (HFmrEF-Increasing: adjusted HR 0.72, 95% CI 0.59-0.88, P = 0.005; HFmrEF-Decreasing: adjusted HR 1.20, 95% CI 1.01-1.44, P = 0.044). Patients with HFmrEF-Decreasing had a similar risk of the composite outcome as patients with HF with reduced EF (adjusted HR 1.03, 95% CI 0.89-1.20, P = 0.670). Patients with HFmrEF-Increasing were less likely to experience the composite outcome compared with patients with HF with preserved EF (adjusted HR 0.73, 95% CI 0.62-0.87, P < 0.001).ConclusionsAmongst patients with HFmrEF, those exhibiting positive LVEF trajectory were less likely to experience adverse outcomes after correcting for important confounders including medical therapy. Categorizing HFmrEF patients based on LVEF trajectory provides meaningful clinical information and may assist clinicians with management decisions.
