OBJECTIVES: This study sought to assess the safety and the efficacy of bivalirudin compared with unfractionated heparin (UFH) alone in the subset of patients at increased risk of bleeding undergoing transfemoral elective percutaneous coronary intervention (PCI). BACKGROUND:Bivalirudin, a synthetic direct thrombin inhibitor, determines a significant decrease of in-hospital bleeding following PCI. METHODS: This is a single-center, investigator-initiated, randomized, double-blind, controlled trial. Consecutive biomarker-negative patients at increased bleeding risk undergoing PCI through the femoral approach were randomized to UFH (UFH group; n = 419) or bivalirudin (bivalirudin group; n = 418). The primary endpoint was the rate of in-hospital major bleeding. RESULTS: The primary endpoint occurred in 11 patients (2.6%) in the UFH group versus 14 patients (3.3%) in the bivalirudin group (odds ratio: 0.78; 95% confidence interval: 0.35 to 1.72; p = 0.54). Distribution of access-site and non-access-site bleeding was 18% and 82% in the UFH group versus 50% and 50% in the bivalirudin group (p = 0.10). CONCLUSIONS: The results of this randomized study, carried out at a single institution, suggest that there is no difference in major bleeding rate between bivalirudin and UFH in increased-risk patients undergoing transfemoral PCI.
