BACKGROUND: Coronary artery bypass grafting (CABG) was performed on patients with cardiopulmonary bypass (CPB group) or without CPB (non-CPB group). A series of CABG patients, performed between January 1, 1995 and September 30, 1997 is included. METHODS: Data were collected and analyzed as determined by the New York State Department of Health. Preoperative comorbidity, postoperative morbidity and mortality were compared. There were 2869 patients in the CPB group and 505 patients in the non-CPB group. RESULTS: Demographics of the two groups were similar but preoperative risk factors were more common in patients undergoing CABG without CPB. Of the non-CPB patients, 31.9% had reoperations as compared to 8.5% in CPB patients (p = 0.00005). The presence of an extensively calcified aorta was more common in the non-CPB patients (5.9% vs. 2.8%, p = 0.0002). Immune deficiency was also more common in the non-CPB group (p = 0.001). Risk-adjusted mortality was similar in the two groups while major complications were much less common when CPB was not utilized. In CPB patients only 84.3% avoided major complications, while among non-CPB patients 90.1% were complication-free (p = 0.0008). CONCLUSIONS: CABG without CPB is an attractive method of surgical revascularization. Increasing age and preoperative comorbidity in patients referred for CABG dictate changes in surgical strategy, of which avoidance of CPB appears most beneficial.
