To present the Cardiology Institute of Rio Grande do Sul experience with percutaneous coronary angioplasty (PTCA), after thrombolytic therapy in acute myocardial infarction (AMI).
Fifty-three patients with transmural AMI in whom early successful intravenous streptokinase recanalization was followed by PTCA. The mean age was 50 years, male patients were more frequent, the predominant area of infarct was anterior wall and more frequently the "culprit" coronary was the left anterior descendent. The main indication of PTCA was uniarterial lesion with less than 20 mm of length.
The success comes out in 44 patients (81.5%). Ten patients (18.5%) were considered unsuccessful and were referred to emergency bypass graft surgery. The in-hospital AMI rate after PTCA was 5.5%. In the follow-up the reestenoses rate was 11% and reocclusion was 3.7%. New PTCA was necessary in 3 patients (5.5%) and in one, by-pass graft (1.8%).
PTCA is an important and secure modality of complementary therapy after thrombolytic therapy with low morbidity and mortality.
介绍南里奥格兰德州心脏病研究所对急性心肌梗死（AMI）溶栓治疗后经皮冠状动脉腔内血管成形术（PTCA）的经验。
53例透壁性AMI患者，早期静脉注射链激酶成功再通后接受PTCA治疗。平均年龄50岁，男性患者更为常见，梗死的主要部位是前壁，“罪犯”冠状动脉最常见的是左前降支。PTCA的主要指征是长度小于20mm的单支血管病变。
44例患者（81.5%）成功。10例患者（18.5%）被认为不成功，并被转诊进行急诊冠状动脉搭桥手术。PTCA术后住院期间的AMI发生率为5.5%。随访中再狭窄率为11%，再闭塞率为3.7%。3例患者（5.5%）需要再次进行PTCA，1例患者（1.8%）需要进行冠状动脉搭桥手术。
PTCA是溶栓治疗后一种重要且安全的辅助治疗方式，发病率和死亡率较低。
