摘　　要：目的评估急性心肌梗死(acute myocardial infarction,AMI)合并糖尿病患者急诊行经皮冠状动脉介入治疗(percutaneous coronary intervention,PCI)围术期应用比伐芦定的安全性及有效性。方法选取BRIGHT研究中AMI合并糖尿病行急诊PCI患者465例,其中比伐芦定组168例,肝素组137例,肝素联合替罗非班组160例。主要终点为术后30 d净不良临床事件(net adverse clinical event,NACE),包括主要不良心脑血管事件(major adverse cardiac and cerebral events,MACCE)及全部出血事件。结果所有患者均完成30 d临床随访。比伐芦定组NACE事件[17例(10.1%)比33例(20.6%),P=0.008]及全部出血事件[5例(3.0%)比20例(12.5%),P=0.001]发生率显著低于肝素联合替罗非班组;与肝素组相比有降低趋势[NACE:17例(10.1%)比22例(16.1%),P=0.122;全部出血事件:5例(3.0%)比10例(7.3%),P=0.082],但差异均无统计学意义。三组间MACCE和支架内血栓发生率比较,差异均无统计学意义(均P>0.05)。结论 AMI合并糖尿病患者急诊PCI围术期应用比伐芦定安全有效,与应用肝素或肝素联合替罗非班相比,可降低术后30 d的NACE和出血事件风险,且不增加MACCE和支架内血栓风险。Objective To evaluate the safety and efficacy of bivalirudin in patients with acute myocardial infarction （ AMI） and diabetes undergoing primary percutaneous coronary intervention （ PCI） . Methods BRIGHT was a multicenter , randomized , controlled study which enrolled AMI patients underwent primary PCI in 83 Chinese centers between August 2012 and June 2013.All patients were randomly assigned to receive bivalirudin , heparin or heparin plus tirofiban. This study was a prespecified subgroup analysis of the BRIGHT study.A total of 465 diabetics in the BRIGHT study were included , consisted of 168 in the bivalirudin group , 137 in the heparin group and 160 in the heparin plus tirofiban group .Primary endpoint was net adverse clinical event （ NACE） at 30 days, which was defined as a composite of major adverse cardiac and cerebral events （ MACCE ） and any bleedings .Results The incidences of NACE at 30 days were significantly different among three arms （ Bivalirudin：10.1% vs.heparin：16.1% vs.Heparin plus tirofiban 20.6%, P=0.031 ） .Compared with heparin plus tirofiban , bivalirudin was associated with a significantly lower NACE rate （P〈0.01）.Bivalirudin treatment significantly reduced bleeding events at 30 days compared with heparin and heparin plus tirofiban （ 3.0% vs.7.3% vs.12.5%, P 〈0.01 ） .The 30-day incidences of MACCE and stent thrombosis were similar among the three groups （ P〉0.05 ） . Conclusions The use of bivalirudin has dramatically reduced the rate of bleeding and did not increase the incidence of ischemic events compared with heparin and heparin plus tirofiban , indicating a better safety and efficacy profile of bivalirudin during primary PCI in patients with AMI and diabetes .
