摘要(Abstract)：

目的研究不同血管重建方式对无保护左主干(ULMCA)末端病变患者治疗的效果及预后意义。方法连续收录冠状动脉造影明确诊断为ULMCA末端病变的222例患者临床资料,其中106例置入药物洗脱支架(PCI组),116例行冠状动脉旁路移植手术(CABG组),观察两组患者在12个月及3年发生全因死亡、非致死性心肌梗死、靶血管重建和主要不良心脏事件发生率,研究不同血管重建方式对ULMCA末端病变治疗效果的影响。结果两组患者在12个月期间,主要终点事件如全因死亡、非致死性心肌梗死差别无统计学意义(分别为:χ2=1.05,P=0.32和χ2=1.04,P=0.38),靶血管重建以及主要不良心脏事件发生率差异有统计学意义(分别为:χ2=5.45,P=0.02和χ2=6.63,P=0.01)。累积3年随访,PCI组与CABG组相比全因死亡率降低33%(10.38%比12.07%,χ2=0.47,P=0.45),但非致死性心肌梗死是后者的1.87倍(2.1%比0,χ2=1.04,P=0.38)。PCI组靶血管重建率是CABG组4.17倍(20.76%比8.62%,χ2=6.63,P<0.01),而主要不良心脏事件两组相比差异有统计学意义(33.02%比20.68%,χ2=4.78,P=0.03)。结论 ULMCA末端病变采用PCI或CABG进行血管重建是安全有效的。对解剖结构适合PCI且患者拒绝或不宜行CABG的ULMCA末端病变患者来说,药物洗脱支架PCI术是一种可以选择的替代治疗方案。
