Abstract
To evaluate the functional results of aortocoronary saphenous bypass surgery, 66 patients aged 33-65 yr (mean 52) underwent a standarized bicycle exercise test before, and at an average of 14 mo. after operation. Capacity for exercise was correlated with symptomatic response and graft patency. Group exercise tolerance was significantly improved after operation, and was about 60% of that of a population-based series of 52 yr old men. After operation 74% of the patients could exercise to fatigue without apparent limiting cardiac symptoms, and 26% were still incapacitated by angina. Improved exercise tolerance correlated with symptomatic improvement and graft patency. Patients with no grafts remaining patent showed no improvement in exercise performance.
