Importance of complete revascularization in performance of the coronary bypass operation

Cardiac Data Bank records of 1,238 patients with triple-vessel disease (≥50% diameter reduction) who had undergone coronary bypass surgery were reviewed and divided into 2 groups depending on whether complete (n = 773) or incomplete (n = 465) revascularization had been accomplished. Patients with complete revascularization had a higher incidence of a normal preoperative electrocardiogram than did patients with incomplete revascularization (23 versus 14%, respectively, p
