Over the last 1-year period, we performed 130 consecutive percutaneous transluminal coronary angioplasty (PTCA) procedures in 108 patients, 103 of them were males and 5 females. Their mean age was 50.9 +/- 6.83 years (range 33-70). All of them were symptomatic, manifested by acute infarction in 18 (17%), chronic stable angina in 30 (28%), unstable angina in 5 (5%) and post-myocardial infarction angina in 55 (51%) cases. Among these patients, single-vessel CAD was present in 42 (39%), double-vessel in 37 (34%) and triple-vessel CAD in 11 (10%) patients. Nine patients (8.3%) had total occlusion, and 18 (16.6%) had tandem or bifurcation lesions of target artery. Of the 112 PTCA procedures (excluding those in acute infarction), 53 (47%) were performed on LAD, 29 (26%) on RCA, and 30 (27%) on circumflex artery, with success rates of 86.7%, 83.3% and 82.7% respectively. The overall success rate was 85% (95 of 112). The PTCA was successful in 36 of 42 (85.7%), 32 of 37 (86.5%) and 9 on 11 (82%) patients with single, double and triple-vessel CAD respectively. The mean diameter stenosis reduced from 67.1 +/- 16.54% to 19.9% +/- 10.9%. PTCA was unsuccessful in 17 (15%) due to failure to cross the lesion in 11 (9.7%), failure to dilate in 1 (0.9%) and abrupt reclosure of dilated segment in 5 (4.4%). Four (3.5%) patients underwent CABG. Two patients had redo PTCA owing to restenosis at about 6 months of first PTCA.(ABSTRACT TRUNCATED AT 250 WORDS)
在过去1年期间，我们对108例患者连续进行了130例经皮腔内冠状动脉成形术（PTCA），其中男性103例，女性5例。他们的平均年龄为50.9±6.83岁（范围33 - 70岁）。所有患者均有症状，表现为急性心肌梗死18例（17%）、慢性稳定型心绞痛30例（28%）、不稳定型心绞痛5例（5%）以及心肌梗死后心绞痛55例（51%）。在这些患者中，单支冠状动脉疾病（CAD）42例（39%），双支37例（34%），三支CAD 11例（10%）。9例患者（8.3%）存在完全闭塞，18例（16.6%）有靶血管串联或分叉病变。在112例PTCA手术（不包括急性心肌梗死患者的手术）中，53例（47%）在左前降支（LAD）进行，29例（26%）在右冠状动脉（RCA）进行，30例（27%）在回旋支进行，成功率分别为86.7%、83.3%和82.7%。总体成功率为85%（112例中的95例）。单支、双支和三支CAD患者的PTCA成功率分别为42例中的36例（85.7%）、37例中的32例（86.5%）和11例中的9例（82%）。平均直径狭窄率从67.1±16.54%降至19.9%±10.9%。17例（15%）PTCA手术失败，其中11例（9.7%）因未能通过病变、1例（0.9%）因未能扩张、5例（4.4%）因扩张段突然再闭塞。4例（3.5%）患者接受了冠状动脉旁路移植术（CABG）。2例患者因首次PTCA术后约6个月再狭窄而接受了再次PTCA。（摘要截断于250字）
