Background:We explored 12-month clinical outcomes of 929 patients with atrial fibrillation (AF) undergoing percutaneous coronary intervention (PCI) with bare-metal stents (BMS) vs. drug-eluting stents (DES) from the prospective multicenter AFCAS (Atrial Fibrillation undergoing Coronary Artery Stenting) registry.Methods and Results:Endpoints included the first occurrence of major adverse cardiac and cerebrovascular events (MACCE), defined as a composite of all-cause death, myocardial infarction (MI), target vessel revascularization, definite/probable stent thrombosis (ST), transient ischemic attack or stroke. Bleeding events were defined according to the Bleeding Academic Research Consortium criteria. Altogether, 673 (72.4%) patients received BMS and 220 (23.7%) at least one DES. Patients treated with DES more often had diabetes and prior ischemic events, and a longer stent length (P<0.05 for all), whereas patients treated with BMS more often had heart failure and were more likely to present with acute ST-elevation MI (P<0.05 for both). At 12-month follow-up, rates and risks of MACCE and total bleeding events were comparable between the groups (22.0% with BMS vs. 19.5% with DES, P=0.51, hazard ratio (HR) 0.89, 95% confidence interval (CI) 0.63–1.25 for DES) and (19.5% vs. 15.0%, respectively, P=0.16, HR 0.75, 95% CI 0.51–1.09 for DES). Definite/probable ST was more frequent in the BMS group (1.9% vs. 0%, respectively, P=0.046).Conclusions:In real-world patients with AF undergoing PCI, DES use was associated with outcomes comparable to those with BMS without excess bleeding complications. More ST was seen in BMS-treated patients. (Circ J 2014; 78: 2674–2681)
