经皮腔内冠状动脉血管成形术对糖尿病并急性心肌梗死的心功能保护作用

目的　研究急诊经皮腔内冠状动脉血管成形术 (PTCA)对糖尿病并急性心肌梗死患者心功能的保护作用。方法　对 4 5例 2型糖尿病并急性心肌梗死患者施行急诊PTCA(PC TA组 ) ,并与同期 4 8例 2型糖尿病并急性心肌梗死而未行PTCA者 (非PTCA组 )进行比较 ,分别观察入院时、住院 2 4h及发病 3个月的心功能分级 (Killip分级 )和发病 3个月的心脏左室射血指数 (LVEF)。结果　两组患者入院时的心功能分级无显著性差异 ;住院 2 4h和发病 3个月的心功能分级 ,及发病 3个月的LVEFPTCA组均明显优于非PTCA组。结论　急诊PTCA能较好保护糖尿病并急性心肌梗死患者的心功能。

Protected effect of percutaneous transluminal coronary angioplasty on cardiac function in diabetes patients with acute myocardial infarction

Objective It is to study the protected effect of percutaneous transluminal coronary angioplasty (PTCA) on cardiac function in diabetes patients with acute myocardial infarction (AMI) at emergency treatment.Methods 45 type-2 diabetic patients with AMI who had underwent emergency PTCA (PTCA group) and 48 type-2 diabetic patients with AMI without who had not underwent emergency PTCA (no-PTCA group) were compared. The cardiac function classification (Killip classification) at hospitalizing, hospitalization after 24 hours and three months after AMI and left ventricular ejection fraction (LVEF) at three months after AMI in the two groups was observed respectively.Results The difference of the Killip classification at hospitalizing between the two groups was not marked. The Killip classification at hospitalization after 24 hours and three months after AMI and LVEF at three months after AMI in PTCA group were significant improved compared with those in no-PCTA group.Conclusion Emergency PTCA can better protect the cardiac function in diabetes patients with AMI.
