A 4.4 year follow-up study has been done on a previously reported group of 200 consecutive patients who underwnet coronary bypass. The yearly mortality rate has been 1% (8/200 in 4 years). Our total group of 1,038 surgically treated patients has had an operative mortality rate of 1.3%, and an early graft patency rate of 89.6% has been recorded in the 60% of patients consenting to restudy. These results are compared to natural history studies with and without angiography. Comparison with recent prospective randomized studies of patients with chronic stable angina and those with unstable angina suggests that a low operative mortality rate and optimal technical performance are necessary to improve the survival rate of patiens with symptomatic obstructive coronary disease.
对先前报道的连续200例接受冠状动脉搭桥手术的患者进行了一项为期4.4年的随访研究。年死亡率为1%（4年中200例中有8例）。我们总共1038例接受手术治疗的患者的手术死亡率为1.3%，在同意再次研究的60%的患者中，早期移植血管通畅率记录为89.6%。这些结果与有无血管造影的自然史研究进行了比较。与近期关于慢性稳定型心绞痛患者和不稳定型心绞痛患者的前瞻性随机研究相比，提示低手术死亡率和最佳技术操作对于提高有症状的阻塞性冠状动脉疾病患者的生存率是必要的。
