经皮冠状动脉腔内成形术对急性心肌梗塞行早期血运重建

１２例急性心肌梗塞患者应用经皮冠状动脉腔内成形术进行早期血运重建，１１例梗塞相关血管再灌注血流为ＴＩＭＩ３级，残留狭窄１５．５±８．８％，１例并发血管内膜夹层形成行紧急冠状动脉旁路移植术，术后死亡。结果认为急性心肌梗塞早期直接进行经皮冠状动脉腔内成形术可实现稳定有效的血运重建，有利于减少心肌梗塞面积及心脏泵功能损害、降低再梗塞率和病死率。

Early revascularization by percutaneous transluminal coronary angioplasty in acute myocardial infarction]

Twelve patients with acute myocardial infarction (AMI) underwent percutaneous transluminal coronary angioplasty (PTCA). The reperfusion blood flow of the infarct-related arteries (IRA) in eleven patients was TIMI Grade 3 with residual stenosis of 15.5 +/- 8.8%. Vascular endothelial dissection complicated by angioplasty was observed in one case and the patient died after emergency coronary artery bypass graft. It is suggested that early primary PTCA in AMI may create stable and effective revascularization which will favor reducing infarct size, improving myocardial pump function, and lowering restenosis and mortality rate.
