AbstractThe efficacy and safety of bivalirudin in percutaneous coronary intervention (PCI) has always been a hot topic in perioperative antithrombotic therapy, but there are still some controversies. So studies are needed to provide more evidence, especially the real world study which includes patients excluded from previous RCT studys. Our study aimed to investigate these information and analyze the independent predictors of postoperative adverse events.A retrospective study enrolled 1416 patients underwent PCI in Tianjin Chest Hospital from May 2016 to October 2017. The incidence of stent-thrombosis and net clinical adverse events, including all-cause death, myocardial infarction, stroke, urgent target-vessel revascularization and bleeding, were followed up for 30 days and 1 year. Logistic regression and COX regression were respectively used to analyze independent predictors of bleeding events within 30-days, and independent predictors of Major adverse cardiovascular and cerebrovascular events (MACCE) in patients with stent implantation within 1-year.Seven hundred six patients were treated with bivalirudin while 710 with unfractionated heparin (UFH). The proportions of diabetes, hypertension, anemia, myocardial-infarction history, PCI history, moderate-to-severe renal-impairment, gastrointestinal-bleeding history in the bivalirudin group were significantly higher (P < .05). Women, anemia were independent risk factors for bleeding within 30-days (P < .05). Among 682 patients with stent implantation in bivalirudin group, anemia, Body Mass Index (BMI) >25 kg/m2, KILLIP ≥2, ejection fraction (EF) <45%, eGFR <60 ml/minutes were independent risk factors for MACCE, while Statins, proton pump inhibitor (PPI) were independent protective factors for MACCE with-in 1-year (P < .05).Bivalirudin have good anticoagulant effect and lower bleeding risk during PCI, especially in patients with higher bleeding risk. In patients treated with bivalirudin, female, anemia were independent predictors of bleeding within 30-days, BMI >25 kg/m2, anemia, KILLIP ≥2, EF <45%, eGFR <60 ml/minutes were independent risk factors and Statins, PPI were independent protective factors of MACCE within 1-year.Copyright © 2021 the Author(s).
