1979年Gruentzig首先报道应用经皮穿刺冠状动脉腔内成形术(PTCA)治疗50例病人的经验。本文旨在回顾这些病例五年的随访结果。方法:50例病人接受PTCA,32例获得成功。其中随访时间超过五年以上者23例(平均62.2±5.6月)。男性22例,女性1例。行PTCA时平均年龄47.5岁(36～64岁)。PTCA前无一例发生心肌梗塞。该23例PTCA前作选择性冠状动脉造影证实:单支血管病变19例[左前降支(LAD)15例,左旋支(LCX)1例,右冠状动脉(RCA)3例];多支血管病变4例。23例中有15例定期进行非创伤性检查。临床检查和心电运动试验每3～6月检查1次,铊运动闪烁图每6～18月1次。其中11例
In 1979 Gruentzig first reported the experience of percutaneous transluminal coronary angioplasty (PTCA) in the treatment of 50 patients. This article aims to review the results of these five-year follow-up visits. Methods: Fifty patients underwent PTCA and 32 patients were successful. Among them, 23 cases were followed up for more than five years (average 62.2 ± 5.6 months). There were 22 males and 1 females. The average age of PTCA was 47.5 years (36-64 years). No case of myocardial infarction preceded PTCA. The 23 cases of PTCA before selective coronary angiography confirmed that: 19 cases of single vessel disease [left anterior descending artery (LAD) in 15 cases, left circumflex artery (LCX) in 1 case, right coronary artery (RCA) in 3 cases]; multivessel disease 4 cases. Fifteen of 23 patients underwent non-invasive tests on a regular basis. Clinical examination and ECG exercise test every 3 to 6 months 1, thallium scintigraphy every 6 to 18 months 1. Of which 11 cases
