Coronary angioplasty was successfully performed in 658/752 multivessel disease patients. One lesion was attempted in 338 patients (45%); two or more in 414 patients (55%). Complications occurred in 39 patients (5.2%): 19 (2.5%) had a transmural infarction, 26 (3.5%) urgent surgery, and 14 (1.9%) died. Recurrence occurred in 233/658 (35%) patients with 162/171 (94.7%) having a successful second angioplasty. Clinical improvement (follow-up: 31 months) remained in 81% of successful patients. Survival was not affected by the number of dilations performed but was adversely affected by the presence of prior surgery and ventricular dysfunction. Angioplasty can be an effective treatment without the need to dilate all vessels.
在752例多支血管病变患者中，658例成功进行了冠状动脉血管成形术。338例患者（45%）尝试对一处病变进行血管成形术；414例患者（55%）尝试对两处或更多处病变进行血管成形术。39例患者（5.2%）出现并发症：19例（2.5%）发生透壁性心肌梗死，26例（3.5%）接受急诊手术，14例（1.9%）死亡。658例患者中有233例（35%）复发，其中171例中有162例（94.7%）成功进行了二次血管成形术。成功患者中81%保持临床改善（随访31个月）。生存率不受血管扩张次数的影响，但受既往手术和心室功能障碍的不利影响。血管成形术可以是一种有效的治疗方法，无需对所有血管进行扩张。
