Evaluation of anticoagulant efficacy and safety for domestic bivalirudin during percutaneous coronary intervention in elderly patients with acute coronary syndrome / 中国介入心脏病学杂志

ABSTRACT

Objective To evaluate the safety and efficacy of bivalirudin during perioperation of percutaneous coronary intervention (PCI) in patients older than 80 years old with acute coronary syndrome. Methods A total of 64 patients were randomly divided into two groups, respectively received heparin(n=32), or bivalirudin (n=32). We compared the activated coagulation time (ACT), procedural success rate, bleeding rate between two groups. Results The two groups ACT, PCI success rates are not statistically different, No signiifcant difference in the incidence of mild hemorrhage which is 4 (12.5%) for heparin and 1(3.1%) for bivalirudin and severe bleeding which is 2 (6.2%) for heparin and 0 for bivalirudin. However there are signiifcant differences in the overall incidence of bleeding between the two groups with lower incidence of beeding in the bivalirudin group than the heparin group (P<0.05). Conclusions Bivalirudin has comparable anticoangulation effect as heparin during perioperation of percutaneous coronary intervention (PCI) among patients older than 80 years of age with acute coronary syndrome with lower bleeding incidence than heparin dose.
