INTRODUCTION: The goal of this study was to determine the association between the use of angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin II receptor blockers (ARBs) and follow-up heart failure (HF) according to left ventricular ejection fraction (LVEF) in patients with acute myocardial infarction (AMI).
METHODS: This cohort study used a retrospective registry of 8169 consecutive patients discharged with a diagnosis of AMI from two university hospitals in Spain between 2010 and 2016. We used a multivariable competing risk analysis, survival-time inverse probability weighting (IPW) propensity score adjusting, and propensity score matching (PSM) to investigate the association between ACEI/ARB treatment and follow-up HF.
RESULTS: During the follow-up (3.3 ± 2.2 years), 1296 patients were admitted for HF (5.2 per 100 person-years). ACEI/ARB use was not associated with fewer follow-up HF admissions in patients with LVEF > 40% (univariate analysis: sub-hazard ratio [sHR] 1.10; 95% confidence interval [CI] 0.95-1.27; p = 0.197; IPW adjusting analysis: sHR 1.11; 95% CI 0.95-1.29; p = 0.192; PSM analysis: sHR 1.12; 95% CI 0.92-1.36; p = 0.248). However, ACEI/ARB use was associated with a significant reduction in HF admission rates in patients with LVEF ≤ 40% (univariate analysis: HR 0.70; 95% CI 0.56-0.88; p = 0.003; IPW adjusting analysis: HR 0.64; 95% CI 0.50-0.83; p = 0.001; PSM analysis: HR 0.65; 95% CI 0.46-0.92; p = 0.014).
CONCLUSION: Among hospitalized survivors of AMI, the use of ACEIs/ARBs was associated with a lower risk of follow-up HF in patients with LVEF ≤ 40% but not in those with LVEF > 40%. Further prospective studies are needed to confirm our results.
