One hundred and six consecutive survivors were re-examined five years after coronary bypass surgery for stable angina pectoris (88 patients) or unstable angina (18 patients). Ninety-two per cent had less symptoms than before operation, 70% were so improved that they were not restricted in daily life and 30% considered themselves free from angina. Excluding one patient, who experienced chest pain at the exercise test and three asymptomatic patients who had undergone repeat operations, only 26% were free from angina at the five-year evaluation. Patients without angina had significantly lower diastolic blood pressure than those with residual symptoms, whereas the type of angina, smoking habits, serum lipids and common risk factors did not differ significantly. Thirteen per cent were employed on admittance for surgery, 49% had been able to work after surgery and 36% of those, who did not have old-age pension or invalidity pension for non-cardiac causes, worked full-time five years after surgery. Patients with sedentary work returned more often (53%) than those with manual labour (22%) and patients with sick-leave less than six months before surgery more often (91%) than those with sick-leave more than two years (13%). Peri-operative infarction was recorded in 5% and a further 10% suffered late myocardial infarction.
106例冠状动脉搭桥手术后的连续幸存者在术后五年接受了复查，这些患者术前患有稳定型心绞痛（88例）或不稳定型心绞痛（18例）。92%的患者症状较术前减轻，70%的患者症状改善明显，日常生活不受限，30%的患者认为自己已无心绞痛症状。排除1例在运动试验时出现胸痛的患者以及3例接受了再次手术的无症状患者后，在五年评估时仅有26%的患者无心绞痛症状。无心绞痛的患者舒张压显著低于仍有残余症状的患者，而心绞痛类型、吸烟习惯、血脂及常见危险因素无显著差异。13%的患者在手术入院时仍在工作，49%的患者术后能够工作，在那些因非心脏原因没有养老金或残疾抚恤金的患者中，36%的人术后五年全职工作。从事久坐工作的患者术后恢复工作的比例（53%）高于从事体力劳动的患者（22%），术前病假少于六个月的患者术后恢复工作的比例（91%）高于术前病假超过两年的患者（13%）。围手术期梗死发生率为5%，另有10%的患者发生晚期心肌梗死。
