延迟经皮冠状动脉介入治疗对急性心肌梗死患者心功能的影响

Effect of heart function on delayed percutaneous coronary artery interventional therapy after acute myocardial infarction

目的评价急性心肌梗死(AMI)后梗死相关血管(IRA)延迟经皮冠状动脉介人治疗(PCI)的疗效。方法对29例AMI后7-14d的患者IRA作PCI后进行临床随访,设同期住院30例AMI患者作对照组,分别比较两组患者近期(术后1月)和远期(术后6月)心功能的变化。结果无论是近期还是远期,介入组比对照组心功能恢复好,均有显著性差异(P<0.01),远期心功能的改善较近期显著,心血管事件的发生率显著下降。结论AMI后,延迟PCI恢复IRA血流对改善左心室心功能及预后有重要的临床意义。

Objective To evaluate the effect of heart function on delayed percutaneous coronary artery interven-tional therapy(PCI) after episode of acute myocardial infarction (AMI) . Methods A follow-up study was conducted on 29 AMI patients with PCI within 7-14 days after the attack. 30 AMI patients without PCI were gathered as control group for comparing the changes of heart function in present stage(1 month post-operation ) and long-term stage (6 months after operation). Results Given the present and long-term stage, the heart function progress of PCI was better than the control group (P<0. 01). The heart function progress in long-term group appeared to be much better than the present one and the rate of heart incidence marked obvious reduction. Conclusion Delayed PCI plays a key role in improving left ventricle heart function and prognosis for victims after AMI.
