BackgroundBeta-blockers improve clinical outcomes in patients with heart failure with reduced ejection fraction (HFrEF). Less is known about their role in older nursing home residents with HFrEF.MethodsFrom the combined OPTIMIZE-HF and Alabama Heart Failure Project data sets, we assembled a propensity score-matched balanced cohort of 6494 hospitalized patients ≥65 years with HFrEF (ejection fraction ≤40%). In our primary approach, hazard ratios (HRs) and 95% confidence intervals (CI)s for outcomes associated with discharge prescriptions for beta- blockers were estimated, examining for heterogeneity by admission from nursing homes. In our sensitivity approach, we examined these associations in a separately assembled propensity score-matched cohort of 122 patients admitted from nursing homes.ResultsIn the matched primary cohort of 6494 patients, HRs (95% CIs) for 12-month all-cause mortality and heart failure readmission were 0.80 (0.74-0.87) and 0.94 (0.86-1.02), respectively. Respective HRs (95% CIs) in the nursing home and non-nursing home subgroups were 0.77 (0.51-1.16) and 0.81 (0.74-0.87) for all-cause mortality (interaction P: 0.653) and 1.06 (0.53-2.12) and 0.89 (0.82-0.96) for heart failure readmission (interaction P: 0.753). In the matched sensitivity cohort of 122 patients admitted from nursing homes, HRs (95% CIs) for 12-month all-cause mortality and heart failure readmission were 0.86 (0.55-1.35) and 1.07 (0.52-2.22), respectively. Similar associations were observed for 30-day outcomes.ConclusionsBeta-blocker use was associated with a lower risk of all-cause mortality but not of heart failure readmission in older patients with HFrEF, which were similar for patients admitted and not admitted from nursing homes.Copyright © 2021 Elsevier Inc.
