Background: Data concerning the impact of stent generation on long-term outcomes in ST-segment elevation myocardial infarction (STEMI) patients with multivessel disease (MVD) who underwent primary percutaneous coronary intervention (PCI) with culprit-only PCI (C-PCI) or multivessel PCI (M-PCI) are limited. Methods: A total of 7,266 patients were separated into the two groups, a C-PCI (n = 4,901) or M-PCI group (n = 2,365). The primary endpoint was the occurrence of major adverse cardiac events (MACE) defined as all-cause death, recurrent myocardial infarction, and any repeat revascularization. The secondary endpoint was the cumulative incidence of stent thrombosis (ST) at 2 years. Results: The cumulative incidence of MACE was significantly higher in the bare-metal stents (BMS) group than the first-generation (1G)-drug-eluting stents (DES) (C-PCI: adjusted hazard ratio [aHR], 1.940; 95% confidence interval [CI], 1.389–2.709; p <.001; M-PCI: aHR, 1.544; 95% CI, 1.099–2.074; p =.038), and the second-generation (2G)-DES group (C-PCI: aHR, 2.271; 95% CI, 1.657–3.114; p <.001; M-PCI: aHR, 2.999; 95% CI, 1.899–4.704; p <.001). In the M-PCI group, 1G-DES showed a higher incidence of MACE compared with 2G-DES (aHR, 1.639; 95% CI, 1.028–2.614; p =.004). The cumulative incidences of ST in the both groups were similar. Conclusion: The cumulative incidence of MACE was the lowest for 2G-DES, the highest for BMS, and intermediate for 1G-DES in the STEMI patients with MVD after C-PCI or M-PCI. However, cumulative incidence of ST in the two different reperfusion strategy groups was similar regardless of stent generation.
