文摘目的 研究老年急性前壁心肌梗死3支血管病变患者应用主动脉内球囊反搏（IABP）的临床效果.方法 符合入选标准的43例患者均行PCI,采取前瞻性的研究方法,以随机数字表非等量随机法,按是否行IABP,将IABP支持的21例作为实验组,未行IABP支持的22例作为对照组,比较2组患者住院期间生存率及远期生存曲线变化.结果 实验组住院期间生存率较对照组明显升高了13.4％（95.2％ vs 81.8％,P=0.011）.Cox回归分析显示,IABP是患者预后的支持因素（β=0.931,OR=0.394,95％CI：0.165-0.942,P=0.036）.实验组远期生存曲线明显优于对照组（84.3％ vs 70.3％,P=0.003）.结论 老年急性前壁心肌梗死3支病变的患者IABP置入能有效提高近期及远期生存率,改善患者预后.
