在慢性冠状动脉完全闭塞患者中进行冠状动脉腔内血管成形术(PTCA)的可行性至今尚未广泛评价,成功病例木后长期临床过程也不甚清楚。本文旨在评价多种临床、血管造影及与血管成形术有关的技木因素对76例冠状动脉完全闭塞患者作PTCA的影响,并讨论PTCA成功患者的长期临床随访。方法:作者在1980年11月至1984年9月对76例冠状动脉完全闭塞而又无急性心肌梗塞的患者作PTCA。男性62例,女性14例,平均年龄56.7岁(38～77岁)。全部患者均有心绞痛。在PTCA前,23例曾有呈Q波的心肌梗塞史,7例伴无Q波梗塞
The feasibility of performing coronary artery endovascular angioplasty (PTCA) in patients with complete occlusion of chronic coronary artery has not been widely evaluated to date, and the long-term clinical success of the successful case is poorly understood. This article aims to evaluate the impact of various clinical, angiographic and angioplasty-related techniques on PTCA in 76 patients with complete occlusion of the coronary artery and to discuss the long-term clinical follow-up of successful PTCA patients. METHODS: The authors performed PTCA in 76 patients with complete occlusion of the coronary artery without acute myocardial infarction between November 1980 and September 1984. 62 males and 14 females, with an average age of 56.7 years (38-77 years). All patients had angina. Prior to PTCA, 23 had a history of myocardial infarction with Q wave and 7 with no Q wave infarction
