Using a retrospective observational study design, we assessed whether all angiotensin-converting enzyme (ACE) inhibitors had similar mortality rates after acute myocardial infarction in patients aged 65 years or older. Our results showed that mortality rates for enalapril, fosinopril, captopril, and quinapril were higher than that for ramipril. This suggests that there is no class effect for ACE inhibitors. Further research is needed to confirm the results of our study.
