Abstract

Objective: To compare major clinical outcomes after successful percutaneous coronary intervention (PCI) with first-generation (1G) drug-eluting stents (DES) and second-generation (2G) DES in patients with acute myocardial infarction (AMI) and prediabetes. Background: Patients with prediabetes are associated with an increased incidence of coronary artery disease. The relative superiority of 1G- and 2G-DES in these patients is not well established. Methods: A total of 4997 patients with AMI and prediabetes were divided into two groups: the 1D-DES group (n = 726) and the 2G-DES group (n = 4271). The primary outcomes were the patient-oriented composite outcomes (POCOs) defined as all-cause death, recurrent myocardial infarction (Re-MI), and any disease revascularization at 2-year follow-up. The secondary outcome was probable or definite stent thrombosis (ST). Results: After propensity score-matching (PSM) analysis, two PSM groups (698 pairs, n = 1396, C-statistics = 0.725) were generated. The cumulative incidence rates of POCOs (hazard ratio (HR): 1.467; 95% confidence interval (CI): 1.068-2.015; p = 0.018), any disease revascularization (HR: 2.259; 95% CI: 1.397-3.654; p = 0.001), and ST (HR: 4.361; 95% CI: 1.243-15.30; p = 0.021) in the 1G-DES group were significantly higher than those in the 2G-DES group. However, the cumulative incidence rates of all-cause death, cardiac death, and Re-MI were similar between the two groups. Conclusions: In patients with AMI and prediabetes, 2G-DES implantation was more efficacious than 1G-DES implantation over a 2-year follow-up period. However, further studies are needed to confirm these results.
