    PurposeThe impact of guideline-directed medical therapy for coronary heart disease in those hospitalized with acute heart failure is unknown.MethodsWe studied guideline-directed medical therapies for coronary disease: angiotensin-converting enzyme (ACE) inhibitors or angiotensin II receptor blockers (ARBs), beta-adrenoreceptor antagonists, antiplatelet agents or anticoagulants, and statins. Using inverse probability of treatment weighting the propensity score, we examined associations of guideline-directed medical therapy intensity (categorized as low [0-1], high [2-3], or very high [4] number of drugs) with mortality in 1873 patients with angina, troponin elevation, or prior myocardial infarction.ResultsAt discharge, 0-1, 2-3, and 4 medications were prescribed in 467 (25%), 705 (38%), and 701 (37%) patients, respectively. Relative to those prescribed 0-1 drugs (reference), all-cause mortality was lower with 2-3 (hazard ratio [HR] 0.48, 95% confidence interval [CI] 0.28-0.84, P = 0.009) or all 4 drug classes (HR 0.56, 95% CI 0.33-0.96, P = 0.034) over 181-365 days, with similar reductions present from 0-180 days. In those with heart failure with preserved ejection fraction, mortality trended lower with 2-3 drug classes (HR 0.43, 95% CI 0.18-1.02, P = 0.054) and was significantly reduced with 4 drugs (HR 0.32, 95%CI 0.12-0.84, P = 0.021) during 0-180 day follow-up. In heart failure with reduced ejection fraction, all-cause mortality was reduced during both 0-180 and 181-365 days when discharged on 2-3 (HR 0.30 for 181-365 days, 95%CI 0.14-0.64, P = 0.002) or all 4 drug classes (HR 0.43, 95%CI 0.19-0.95, P = 0.038).ConclusionsIncreasing guideline-directed medical therapy intensity for coronary heart disease resulted in lower mortality in patients with acute ischemic heart failure with both preserved and reduced ejection fractions.Copyright © 2020 The Authors.
