Abstract
Objective
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 elderly (≥ 65) acute myocardial infarction (AMI) patients without a history of hypertension who underwent successful percutaneous coronary intervention (PCI) with drug-eluting stents (DES).
Methods
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.
Results
The patients were divided into two groups: the ACEI group, n = 872 patients and the ARB group, n = 508 patients. After IPTW matching, baseline characteristics were balanced. During the 3-year clinical follow-up, the incidence of MACE was not different between the two groups. However, incidence of stroke (hazard ratio [HR], 0.375; 95% confidence interval [CI], 0.166–0.846; p = 0.018) and re-hospitalization due to heart failure (HF) (HR, 0.528; 95% CI, 0.289–0.965; p = 0.038) in the ACEI group were significantly lower than in the ARB group.
Conclusion
In elderly AMI patients who underwent PCI with DES without a history of hypertension, the use of ACEI was significantly associated with reduced incidences of stroke, and re-hospitalization due to HF than those with the use of ARB.
