Objective

To examine the impact of tissue selectivity of angiotensin-converting enzyme (ACE) inhibitors on mortality and morbidity in patients following acute myocardial infarction (AMI).

Methods

A retrospective cohort study using a Medicaid claims database was conducted. Patients hospitalized for an AMI and subsequently filling a prescription for an ACE inhibitor were followed longitudinally for the occurrence of cardiovascular-related hospitalizations and all-cause mortality. A subanalysis was also conducted to account for switching/discontinuation of ACE inhibitor therapy. Stepwise (forward conditional) Cox-proportional hazards models were used to analyze the effect of tissue selectivity on study outcomes.

Results

The final study sample consisted of 689 AMI and the results indicated that tissue-selective ACE inhibitors had a protective effect against hospitalization due to stroke/transient ischemic attack (TIA) (hazard ratio [HR] = 0.265; 95% confidence interval [CI] = 0.101–0.698). A similar lower rate in hospitalizations due to heart failure was observed in the group using tissue-selective ACE inhibitors; however, the results were not statistically significant (HR = 0.681; 95% CI = 0.436–1.063). A protective effect was also observed on the combined outcome of hospitalization due to any cardiovascular condition (HR = 0.712; 95% CI = 0.536–0.945). Hospitalizations due to recurrent AMI, need for coronary revascularization procedures, and mortality were not significantly different between patients using tissue-selective and non-tissue-selective ACE inhibitors. The completer subanalysis provided similar findings regarding the impact of tissue selectivity on study outcomes.

Conclusion

Tissue-selective ACE inhibitors may have a protective effect against hospitalization due to stroke/TIA or heart failure when compared to non-tissue-selective ACE inhibitors for patients following AMI.
