A group of patients with failed angioplasty who then required emergency coronary bypass was compared with a historically matched group of patients who had had elective bypass grafting. The two groups were well matched in age, sex, ejection fraction, and New York Heart Association classification and in the incidence of diabetes and hypertension. Significant differences were found in the prevalence of mortality (12% versus 1.5%), hemorrhage (28% versus 13%), cardiac tamponade (10.5% versus 1.5%), myocardial infarction (28% versus 9%), and length of hospital stay (15.3 days versus 13.4 days). Cardiogenic shock carries the worst prognosis; four of the five patients with this condition died. Because emergency operation after failed angioplasty carries with it significant postoperative morbidity and mortality, this procedure cannot be considered equivalent to elective coronary bypass grafting.
将一组血管成形术失败后需要进行紧急冠状动脉搭桥手术的患者与一组历史对照的择期搭桥手术患者进行了比较。两组在年龄、性别、射血分数、纽约心脏协会分级以及糖尿病和高血压的发生率方面匹配良好。在死亡率（12% 对 1.5%）、出血（28% 对 13%）、心脏压塞（10.5% 对 1.5%）、心肌梗死（28% 对 9%）和住院时间（15.3 天对 13.4 天）的患病率上发现了显著差异。心源性休克的预后最差；患有这种疾病的五名患者中有四名死亡。由于血管成形术失败后的急诊手术伴随着显著的术后发病率和死亡率，因此该手术不能被认为等同于择期冠状动脉搭桥手术。
