冠心病急性心肌梗死急性期后择期PCI时机的选择及对左室功能的影响

Effect of Elective Percutancous Coronary Intervention's time on Left Ventricular Systolic Funtion in Patients with Myocardial Infantion

目的:探讨冠心病急性心肌梗死(AMI)急性期后病例不同时间择期PCI术对左室功能影响。方法:选择冠心病AMI急性期后病例120例,分为三组,分别于AMI后10天～2周、2周～1月、3月～1年行择期PCI术治疗,运用经胸超声心动图于术前及术后半年测定左室功能指标EF、WMSI、LVED、E/A以评价左室功能,并进行组间对比分析。结果:冠心病AMI后10天-2周择期PCI组、2周～1月择期PCI组术后EF、WMSI、E/A等左室功能指标与3月～1年择期PCI组,比较有显著性差异(P<0.01或P<0.05),10天～2周择期PCI组与2周～1月择期PCI组术后各项左室功能指标比较无显著性差异(P>0.05)。结论:冠心病AMI急性期后病例择期PCI宜选择在心肌梗死后1月内完成PCI治疗,可改善左室功能,改善预后。

Objective： To explore the effect of derive PCI＇ s time on left ventricular systolic Function at different stage of MI. Metheds：120 cases with MI were divided into 3 groups 10 day - 2weeks. 2weeks ~1months and 3 months ~ 1 years.They Were treated by PCI, To measure the date of LV systelic function（WMIS, EF, LVED, E/A） by UCG before and in 6 months after PCI in order to evaluate LV systolic Function and to contrast the data. Results： The date was obviously different deturech 10 day ~ 2 weeks and 2weeks ~ 1 months groups and 3months ~ lyears groups, But There was hardly different between 10day ~ 2weeks groups and 2weeks ~ 1 months groups. Conclusion： the accomplishment of elective PCI can improve LV systolic Function and proghosis in the patients with AMI in 1 months after MI.
