对１５例急性心肌梗塞，行紧急冠状动脉造影术，其中１２例进行了直接经皮腔内冠状动脉成形术（ＰＴＣＡ），１０例成功，２例因导引钢丝不到位而失败。其余３例因严重的３支血管病变而采取药物治疗。单支血管病变５例，两支以上血管病变者５例。急性下壁心梗５例（２例合并正后壁心梗），前壁心梗４例，高侧壁合并下壁心梗１例。有２例合并心源性休克，２例合并左心衰。梗塞相关血管段，右冠状动脉５段，前降支４段，回旋支１段。术后残留狭窄从９８％下降至２２％。冠脉血流从ＴＩＭＩ０～Ⅱ级全部达到Ⅲ级。
In 15 patients with acute myocardial infarction, urgent coronary angiography was performed. Among them, 12 cases underwent direct percutaneous transluminal coronary angioplasty (PTCA), 10 cases were successful, and 2 cases failed because the guide wire was not in place. The remaining 3 cases were treated with medication due to severe 3-vessel disease. Single vessel disease in 5 cases, more than two vascular lesions in 5 cases. 5 cases of acute inferior myocardial infarction (2 cases with posterior wall myocardial infarction), 4 cases of anterior myocardial infarction, 1 case of inferior wall combined with high myocardial infarction. There were 2 patients with cardiogenic shock, 2 patients with left heart failure. Infarction-related vascular segment, right coronary artery 5, anterior descending artery 4, cyclotron branch 1. Postoperative residual stenosis decreased from 98% to 22%. Coronary blood flow from grade TIMI0 ~ Ⅱ all reached Ⅲ grade.
