Angiotensin-converting enzyme inhibitors versus angiotensin II receptor blockers in acute ST-segment elevation myocardial infarction patients with diabetes mellitus undergoing percutaneous coronary intervention

초록

Background: Diabetes Mellitus (DM) is an important factor of adverse cardiovascular events in acute ST-segment elevation myocardial infarction (STEMI) patients. Renin-angiotensin-aldosterone system (RAAS) inhibitors is associated with improved clinical outcomes, however, there are limited data comparing the effectiveness of two different RAAS inhibitors in STEMI patients with DM undergoing percutaneous coronary intervention (PCI) with drug-eluting stents (DES). Methods: A total of 3811 eligible STEMI patients with DM were enrolled in Korea Acute Myocardial Infarction Registry (KAMIR). They were stratified into two groups: Angiotensin converting enzyme inhibitors (ACEI) group (n = 2691) and angiotensin receptor blockers (ARB) group (n = 1120). To adjust baseline confounding factors, we performed propensity score matching (PSM) analysis and evaluated individual and composite major clinical outcomes between the two groups up to 2 years. Results: After PSM, a total of 1049 well-matched pairs were generated. Baseline clinical, angiographic and procedural characteristics were well-balanced between the two groups. The incidence of death, recurrent myocardial infarction (MI), revascularization and major adverse cardiac events (MACE) were not significantly different between the two groups up to 2 years, Conclusion: In the present study, ACEI and ARB showed comparable effectiveness and safety on individual and composite clinical outcomes in STEMI patients with DM who underwent successful PCI with DES at least up to 2 years.
