The impact of angiotensin-converting-enzyme inhibitors versus angiotensin receptor blockers on 3-year clinical outcomes in patients with acute myocardial infarction without hypertension

초록

This study aimed to investigate the impact of angiotensin-converting-enzyme inhibitors (ACEI) and angiotensin II type 1 receptor blockers (ARB) on 3-year clinical outcomes in acute myocardial infarction (AMI) patients without a history of hypertension who underwent successful percutaneous coronary intervention (PCI) with drug-eluting stents (DES). A total of 13,104 AMI patients who were registered in the Korea AMI registry (KAMIR)-National Institutes of Health (NIH) were included in the study. The primary endpoint was 3-year major adverse cardiac events (MACE), which was defined as the composite of all-cause death, recurrent myocardial infarction (MI), and any repeat revascularization. To adjust baseline potential confounders, an inverse probability weighting (IPTW) analysis was performed. The patients were divided into two groups: the ACEI group, n = 4,053 patients and the ARB group, n = 4,107 patients. During the 3-year clinical follow-up, the cumulative incidences of MACE (hazard ratio [HR], 0.843; 95% confidence interval [CI], 0.740–0.960; p = 0.010), any repeat revascularization (HR, 0.856; 95% CI, 0.736–0.995; p = 0.044), stroke (HR, 0.613; 95% CI, 0.417–0.901; p = 0.013), and re-hospitalization due to heart failure (HF) (HR, 0.399; 95% CI, 0.294–0.541; p <0.001) in the ACEI group were significantly lower than in the ARB group. In Korean patients with AMI without a history of hypertension, the use of ACEI was significantly associated with reduced incidences of MACE, any repeat revascularization, stroke, and re-hospitalization due to HF than those with the use of ARB. © 2020 Her et al.
