Aim: To investigate the comparative effectiveness of renin-angiotensin system inhibitor (RASI) therapy on major clinical outcomes in patients with acute myocardial infarction (AMI) and prediabetes or diabetes after successful percutaneous coronary intervention (PCI) with newer-generation drug-eluting stents (DESs). Methods: A total of 11,962 patients with AMI were divided into six groups according to glycemic status and the presence or absence of RASI therapy: normoglycemia (n = 3,080; RASI+ [n = 2,496], RASI− [n = 584]), prediabetes (n = 3,709; RASI+ [n = 2,944], RASI− [n = 765]), and diabetes (n = 5,173; RASI+ [n = 4,133], RASI− [n = 1,040]). The major endpoint was major adverse cardiac events (MACEs), defined as all-cause death, recurrent myocardial infarction (re-MI), or any repeat revascularization. Results: After adjustment, in RASI users, the cumulative incidence of re-MI of the diabetes group was significantly higher than that of the prediabetes group (aHR, 1.999; 95% CI, 1.153–3.467; p = 0.014). However, the cumulative incidences of MACEs, all-cause death, and any repeat revascularization were similar between the two groups during a 2-year follow-up period. Conclusions: In the era of newer-generation DESs, RASI therapy did not reduce re-MI in patients with AMI and diabetes in this study.
