NEJM:冠状动脉旁路移植术体外循环对术后的影响

2017-08-17 zhangfan MedSci原创

研究认为,对于接受冠状动脉旁路移植术的患者,不进行体外循环患者的5年临床结果由于接受体外循环的患者

冠状动脉旁路移植术(CABG)根据是否使用体外循环分为两类:体外循环下冠状动脉旁路移植术(On-Pump CABG)及非体外循环冠状动脉旁路移植术(Off-Pump CABG)。近日研究人员考察了体外循环对患者5年临床结果的影响。研究在18个医疗中心招募了2203名患者,随机采取体外循环或非体外循环。主要终点包括5年全因死亡和心血管综合事件,次要终点包括心血管事件死亡、血运重建、非致死性心肌梗死。研究发现,非循环组vs循环组5年死亡率: 15.2% vs 11.9% (rr, 1.28; 95% CI, 1.03-1.58; P=0.02);5年的主要心血管事件发生率:31.0%  vs 27.1% (rr, 1.14; 95% CI, 1.00 -1.30; P=0.046)。组间次要终点无显著差异,非致死性心肌梗死: 12.1% vs 9.6%(P=0.05); 心血管事件死亡: 6.3%vs5.3% (P=0.29); 血运重建:13.1% vs 11.9% (P=0.39);二次CABG 1.4% vs 0.5% (P=0.02)。研究认为,对于接受冠状动脉旁路移植术
