概要	BACKGROUND: Using the standard maintenance dose of prasugrel (10 mg/day) as part of triple therapy with aspirin and an oral anticoagulant (OAC) is not recommended in the current guidelines because it increases the risk of bleeding compared with clopidogrel. However, the safety and efficacy of low-dose prasugrel (3.75 mg/day) as part of triple therapy has not been reported. Methods and Results: We registered 816 consecutive patients with atrial fibrillation (AF) who underwent percutaneous coronary intervention (PCI) from January 2011 to June 2016 at 8 hospitals in Japan. We examined the clinical outcomes of patients who received either low-dose prasugrel (n=57) or clopidogrel (n=451) as part of triple therapy after PCI. The incidences of bleeding (TIMI major and minor) and major adverse cerebrocardiovascular events (MACCE; all-cause death, nonfatal myocardial infarction, stent thrombosis, unplanned revascularization, and stroke) were evaluated. The cumulative 1-year incidence of bleeding was not significantly different (prasugrel 5.6% vs. clopidogrel 8.1%, log-rank P=0.55). In addition, the cumulative 1-year incidence of MACCE was also not significantly different (prasugrel 11.5% vs. clopidogrel 12.3%, log-rank P=0.88). CONCLUSIONS: Low-dose prasugrel, as part of triple therapy, did not increase the risk of bleeding compared with clopidogrel. Therefore, it can be an alternative to clopidogrel for patients with AF undergoing PCI.
