目的 :评价急性心肌梗死 (AMI)患者起病 1个月内行延迟经皮冠状动脉介入 (PCI)术的疗效。方法 :回顾性分析 2 12例首次AMI患者中 14 6例行延迟PCI术 (执行时间中位数 :发病后 15 .8d)与 6 6例未行延迟PCI术患者住院期死亡和起病 1年内死亡、再次AMI和死亡或 (和 )再次AMI的发生率。结果 :行延迟PCI术的患者与未行延迟PCI的患者相比 ,其住院期死亡 (2 .1%∶2 4 .0 % ,P <0 .0 1)、起病 1年内死亡 (2 .7%∶9.1% ,P <0 .0 1)、再次AMI(2 .1%∶6 .1% ,P <0 .0 5 )和死亡或 (和 )再次AMI(3.4 %∶13.6 % ,P <0 .0 1)的发生率均显著降低。多因素分析显示PCI术能独立降低AMI患者住院期死亡率 (OR 0 .0 2 8,95 %CI 0 .0 8～ 0 .112 )和 1年内死亡或 (和 )再次AMI的发生率 (OR 0 .191,95 %CI 0 .0 6～ 0 .6 0 8)。结论 :AMI后 1个月内行延迟PCI术能使AMI患者受益
Objective: To evaluate the efficacy of delayed percutaneous coronary intervention (PCI) within 1 month of onset of acute myocardial infarction (AMI). Methods: A retrospective analysis was performed in 146 patients with first AMI in 21 cases who underwent delayed PCI (median duration of execution: 15.8 days after onset) and 6 6 patients who died without PCI during the hospitalization period and within 1 year of onset Death, AMI again, and death or (or) AMI again. Results: In-hospital death (2.1%: 24.0%, P <0.01) was significantly lower in patients who underwent PCI than in patients who did not receive delayed PCI (P <0.01). P <0.01), AMI again (2.1%: 6.1%, P <0.05) and death or AMI again (3.4% vs 13.6%, P <0. 01) were significantly lower incidence. Multivariate analysis showed that PCI was able to independently reduce the in-hospital mortality (OR0.082.85% CI0.0-0.112) and the rate of death or (or) AMI within 1 year in patients with AMI 0 .191, 95% CI 0 .0 6 ~ 0.608). Conclusion: Delayed PCI within one month after AMI can benefit AMI patients
