Prognostic impact of additional mineralocorticoid receptor antagonists in octogenarian heart failure patients.

ABSTRACT: AIMS:Guideline-directed medical therapy (GDMT) including beta-blockers and renin-angiotensin system inhibitors is shown to reduce mortality risk in patients with heart failure (HF) and reduced left ventricular ejection fraction (LVEF). However, there is little evidence about the efficacy of additional administration of mineralocorticoid receptor antagonists (MRAs) with GDMT in patients ?80 years presenting with HF. We aimed to investigate the prognostic impact of GDMT with MRA in relation to the age of patients with HF. METHODS AND RESULTS:This observational study included patients admitted for HF with reduced LVEF who were discharged alive; among them, 224 patients were ?80 years, and 661 patients were <80 years. Both populations were divided into three groups depending on whether they received GDMT with or without MRA or single/no GDMT drugs (GDMT+MRA+, GDMT+MRA-, or non-GDMT, respectively). The primary endpoint was all-cause mortality. In patients ?80 years, all-cause mortality was the lowest in the GDMT+MRA+ group (log-rank trend, P = 0.034), and no significant differences were observed between the GDMT+MRA- and non-GDMT groups. Multivariate Cox regression analysis revealed that GDMT+MRA+ was superior to GDMT+MRA-, even after adjusting for parameters at discharge (hazard ratio: 0.32, 95% confidence interval: 0.11-0.99). In patients <80 years, GDMT reduced all-cause mortality; however, additional MRA was not associated with an improved outcome. CONCLUSIONS:The results of this study suggest that additional MRA to GDMT at discharge is one of the therapeutic options for elderly HF patients with reduced LVEF. This finding is not well documented in previous clinical trials.

Project description:AimsThis study aims to investigate the prognostic impact of mineralocorticoid receptor antagonists (MRAs) on cardiovascular events in patients hospitalized for acute decompensated heart failure with preserved ejection fraction (HFpEF; defined as left ventricular ejection fraction ≥45%).Methods and resultsA prospective multicentre cohort study was conducted in Nagano prefecture, Japan, between July 2014 and December 2018 that contained 518 consecutive HFpEF patients hospitalized for acute decompensated heart failure (HF). The primary outcome was a composite of cardiovascular death and HF readmission. We compared the incidence of cardiovascular events between patients who were prescribed with MRAs and those who were not in a propensity score matched cohort using a Cox proportional hazards regression model with a propensity score derived from 23 baseline variables. For sensitivity analysis, we conducted Cox proportional hazards regression models for the primary outcome adjusting for 16 clinically relevant variables in the crude cohort. The median age was 83 years, and 53% were female. The median left ventricular ejection fraction was 61%. During a median follow-up of 553 days, the primary outcome occurred in 192 (37%) patients. MRAs were used in 255 (49%) patients. After analysis, a matched cohort consisting of 370 patients was created. After propensity score matching, the baseline characteristics were well balanced between the two groups. The incidence of the primary outcome was significantly lower in MRA users than in non-users [32% (59/185) vs. 49% (90/185); hazard ratio (HR) 0.669, 95% confidence interval (CI) 0.482-0.929, P = 0.016]. The incidence of cardiovascular death was also significantly lower in the MRA users [11% (21/185) vs. 22% (41/185); HR, 0.563; 95% CI, 0.333-0.953; P = 0.032]. The risk of HF readmission tended to be lower in the MRA users [29% (54/185) vs. 41% (75/185); HR, 0.738; 95% CI, 0.520-1.048; P = 0.089]. MRA use was also associated with a lower risk of the primary outcome after Cox proportional hazards analysis adjusting for 16 clinically relevant variables in the crude cohort (HR, 0.710; 95% CI 0.507-0.995; P = 0.047).ConclusionsMineralocorticoid receptor antagonist use was significantly associated with a lower risk of the primary composite outcome of cardiovascular death and HF readmission in patients hospitalized for acute decompensated HFpEF. The incidence of cardiovascular mortality was also significantly lower in these patients.

Project description:OBJECTIVES:The purpose of this study was to investigate the effects of mineralocorticoid receptor antagonists (MRAs) on systolic blood pressure (SBP) and outcomes according to baseline SBP in patients with heart failure with reduced ejection fraction (HFrEF). BACKGROUND:MRAs are greatly underused in patients with HFrEF, often because of fear of adverse events. Concern about hypotension has been raised by the demonstration that MRAs are particularly effective treatment for resistant hypertension. METHODS:The effect of MRA therapy was studied in 4,396 patients with HFrEF randomized in the RALES (Randomized Aldactone Evaluation Study) and EMPHASIS-HF (Eplerenone in Mild Patients Hospitalization and Survival Study in Heart Failure) trials. RESULTS:Mean SBP change from baseline to 6 months was +1.4 ± 18.1 mm Hg in the placebo group and -1.2 ± 17.9 mm Hg in the MRA group. The between-treatment difference was 2.6 mm Hg (95% confidence interval [CI]: 1.5 to 3.6; p < 0.001). All outcomes were reduced by MRA therapy overall, with consistent effects across SBP categories (e.g., all-cause mortality, overall hazard ratio [HR] of 0.72; 95% CI: 0.64 to 0.82; p < 0.001; SBP ?105 mm Hg; HR: 0.72; 95% CI: 0.56 to 0.94; SBP >105 to ?115 mm Hg; HR: 0.78; 95% CI: 0.60 to 1.02; SBP >115 to ?125 mm Hg; HR: 0.71; 95% CI: 0.53 to 0.94; SBP >125 to ?135 mm Hg; HR: 0.79; 95% CI: 0.57 to 1.10; and SBP > 135 mm Hg; HR: 0.67; 95% CI: 0.50 to 0.90; p for interaction = 0.95). Hypotension was infrequent and not more common with MRA therapy than with placebo, overall (4.6% vs. 3.9%; p = 0.25) or in any SBP category. CONCLUSIONS:MRA treatment had little effect on SBP in patients with HFrEF, and the clinical benefits were not modified by baseline SBP. MRA treatment infrequently caused hypotension, even when the baseline SBP was low. The treatment discontinuation rates between MRA and placebo therapy were similar. Low SBP is not a reason to withhold MRA therapy in patients with HFrEF.
