Name of journal: The American journal of cardiologyAbstract: The randomized TRial to Assess Improvement in Therapeutic Outcomes by Optimizing Platelet InhibitioN with Prasugrel-Thrombolysis In Myocardial Infarction (TRITON-TIMI) 38 trial compared prasugrel and clopidogrel in patients with acute coronary syndrome undergoing percutaneous coronary intervention (PCI). Patients treated with prasugrel had fewer ischemic events but more procedure-related bleeding. In the present study, we aimed to determine the effect of bivalirudin on bleeding in patients treated with prasugrel. A total of 692 patients with consecutive acute coronary syndrome underwent PCI with stent implantation and were anticoagulated with bivalirudin. The patients were divided into 2 groups according to the antiplatelet regimen (clopidogrel or prasugrel) chosen during or just after PCI. The bleeding complications during hospitalization were tabulated. Ischemic events were analyzed during hospitalization and at 30 days. Prasugrel was used in 96 patients (13.9%) and clopidogrel in 596 (86.1%). The clinical and procedural characteristics were similar, although the clopidogrel patients more often reported systemic hypertension (p = 0.01), previous PCI (p <0.001), and chronic renal insufficiency (p = 0.05). During hospitalization, the bleeding and ischemic complication rates were similar and low in both groups (major in-hospital complications 4.2% for clopidogrel vs 2.1% for prasugrel, p = 0.6; Thrombolysis In Myocardial Infarction major bleeding 2.5% vs 2.1%, p = 1.00; Thrombolysis In Myocardial Infarction minor bleeding 4.2% vs 5.2%, p = 0.6). At 30 days, no differences were found in ischemic events between both groups (target vessel revascularization/major adverse cardiac events 5.4% vs 2.1%, p = 0.2). In conclusion, prasugrel, when given after bivalirudin as the intraprocedural antithrombin agent for patients with acute coronary syndrome undergoing PCI, is as safe and effective as clopidogrel.
