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.
12例急性心肌梗死（AMI）患者接受了经皮腔内冠状动脉成形术（PTCA）。11例患者梗死相关动脉（IRA）的再灌注血流为TIMI 3级，残余狭窄为15.5±8.8%。1例患者发生血管内皮夹层并伴有血管成形术并发症，该患者在紧急冠状动脉搭桥术后死亡。提示AMI早期直接PTCA可实现稳定有效的血管重建，这将有助于缩小梗死面积、改善心肌泵功能并降低再狭窄率和死亡率。
