老年急性心肌梗死患者急诊PCI的疗效

Clinical effect of PCI in old patients with acute myocardial infarction

目的:探讨直接经皮冠状动脉介入治疗(PCI)对老年急性心肌梗死(AMI)的疗效。方法:75例AMI 患者在发病12小时内接受冠状动脉造影,并对73例的梗死相关动脉行急诊PCI,随访1～12个月主要心血管事件发生情况。结果:73例接受PCI 的患者中7例行单纯PTCA,66例(88%)置入支架;2例行急诊冠状动脉旁路移植术(CABG);1例术中发生室颤,复律无效死亡,共有3例于住院期间死亡。随访期间主要心血管事件发生率11. 6% (8/69) ,其中2例猝死,4例出现再梗死,2例因支架内再狭窄行再次PCI。结论:急诊经皮冠状动脉介入术治疗老年急性心肌梗死可有效地使梗死相关动脉再通,成功率高,死亡率低,近期预后良好。

Objective： To evaluate the clinical effect of PCI for acute myocardial infarction （AMI） in aged patients.Methods：Seventy-three AMI patients underwent urgent PCI. The baseline clinical characterisstics and coronary artery lesions were analyzed and major cardiovascular events （MCVE） were followed-up during period of 1-12 months.Results：Of 73 patients underwent urgent PCI, seven patients were performed PTCA, 66 patients were performed PTCA and stenting; two patients were performed urgent CABG; one patient died of VF during operation; three patients died during hospital; MCVE rate during follow-up was 11.60% （8/69）. Conclusion： The emergency PCI in acute myocardial infarction has high successful and few complications.
