Background and aims: There are limited data comparing clinical outcomes among new-generation drug-eluting stents (DES) in ST-segment elevation myocardial infarction (STEMI) patients with multivessel coronary artery disease (MVD) who underwent primary percutaneous coronary intervention (PCI) with culprit-only or multivessel PCI. We investigated 1-year clinical outcomes between biodegradable-polymer (BP)-coated biolimus-eluting stent (BES) and durable-polymer (DP)-coated DES in STEMI patients with MVD who underwent two different reperfusion strategies. Methods: A total of 4255 patients were enrolled and divided into two groups, a culprit-only (n = 2571, BP- [n = 264] or DP-DES [n = 2307]) or a multivessel PCI group (n = 1684, BP- [n = 145] or DP-DES [n = 1539]). The primary endpoint was major adverse cardiac events (MACE) defined as all-cause death, recurrent myocardial infarction (re-MI), and total repeat revascularization. The secondary endpoint was the incidence of definite or probable stent thrombosis (ST). Results: BP-BES and DP-DES showed a similar 1-year adjusted hazard ratio (HR) for MACE (culprit-only, adjusted hazard ratio [HR], 1.114; p = 0.740; multivessel, HR, 0.564; p = 0.167) and ST (culprit-only, HR, 1.110, p = 0.891; multivessel, HR, 0.375; p = 0.402). The adjusted HR for all-cause death, re-MI, and repeat revascularization were similar between the two groups. In the total population, the culprit-only PCI group showed a higher incidence of total repeat revascularization than the multivessel PCI group. Conclusions: BP-BES and DP-DES showed comparable safety and efficacy in STEMI patients with MVD who underwent primary PCI with two different reperfusion strategies during a 1-year follow-up period.
