Abstract
We evaluated long-term survival after coronary-artery bypass grafting in 686 patients with stable angina who were randomly assigned to medical or surgical treatment at 13 hospitals and followed for an average of 11.2 years. For all patients and for the 595 without left main coronary-artery disease, cumulative survival did not differ significantly at 11 years according to treatment. The 7-year survival rates for all patients were 70 per cent with medical treatment and 77 per cent with surgery (P = 0.043), and the 11-year rates were 57 and 58 per cent, respectively. For patients without left main coronary-artery disease, the 7-year rates were 72 and 77 per cent in medically and surgically treated patients, respectively (P = 0.267), and the 11-year rates were 58 per cent in both groups.
