Long-term follow-up of patients with coronary artery bypass grafts.
A follow-up study of 1532 patients who had coronary artery bypass grafts from 1969 through 1974 revealed that the 5-year survival rate was substantially better than that recorded in previously published series of patients with similar disease demonstrated angiographically who did not undergo operation. Within this group of operated patients, those who had complete myocardial revascularization (i.e., three grafts for those with three-vessel disease) experienced a significantly better long-term prognosis than those who had fewer grafts than the number of vessels obstructed. The mortality curve in the completely revascularized patients was very similar to that of the general population of the United States, corrected to correspond to this patient sample in age and sex.
