为评估75岁以上病人经皮冠脉成形术(PTCA)或冠脉旁路移植术(CABG)的临床疗效,作者研究了1980～1987年间收治的93例行PTCA和81例行CABG的老年病人,年龄分别为75～89和75～84岁,随访时间分别为8.2和8.3年,心绞痛分级均为Ⅲ～Ⅳ级(加拿大心血管病学会标准)。通过调查其住院期间并发症及随访期间的生存率后发现,PTCA组首次治疗成功率为84％(78/93),治疗失败者7例(5例行择期CABG,2例保守治疗),2例死亡,2例行紧急CABG,3例出现心肌梗死,1例出现脑血管意外,平均住院时间4.3天;CABG组首次治疗成功率为63％(53/81),6例死亡,2例出现脑血管意外,8例发生心肌梗死,10例再次手术。4例发生成人呼吸窘迫综合征,平均住
To assess the clinical efficacy of percutaneous transluminal coronary angioplasty (PTCA) or coronary artery bypass grafting (CABG) in patients over 75 years old, the authors studied 93 elderly PTCA patients and 81 elderly patients with CABG admitted between 1980 and 1987 , Aged 75-89 and 75-84 years old respectively. The follow-up time was 8.2 and 8.3 years respectively. The grade of angina pectoris was grade Ⅲ ~ Ⅳ (Canadian Cardiovascular Society standard). Through investigating the complications during hospitalization and the survival rate during follow-up, it was found that the success rate of initial treatment in PTCA group was 84% (78/93), treatment failure in 7 cases (5 cases of elective CABG, 2 cases of conservative treatment), 2 2 died of acute CABG, 3 cases of myocardial infarction, 1 case of cerebrovascular accident, the average hospital stay of 4.3 days; CABG group, the first treatment success rate was 63% (53/81), 6 died and 2 cases Cerebrovascular accident, myocardial infarction in 8 cases and reoperation in 10 cases. 4 cases of adult respiratory distress syndrome, the average live
