Off-pump coronary artery bypass grafting (Off-Pump CABG) may provide an alternative form of surgical revascularization by avoiding the unwanted complications of cardiopulmonary bypass, particularly in high-risk patients. To clarify the efficacy and cost performance of Off- Pump CABG, we studied the postoperative course of Off-Pump CABG and compared it to On- pump coronary artery bypass grafting (On-Pump CABG). From Aug. 1998 to Feb. 2002, twenty-eight patients who had preoperative complications such as cerebral vascular disease (11), chronic renal failure (4), atheromatous aorta (4), one lung (1), severely impaired left ventricular function (6), re-do CABG (1), and cancer (1) underwent Off- Pump CABG. Another thirty-six patients who underwent On-Pump CABG served as a control. The Off-Pump CABG patients were almost the same age as the On-Pump CABG patients (68 ± 8 vs 64 ± 8 years, ns). The Number of grafts was similar in both groups (2.6 ± 1.0 vs 2.9 ± 1.0, ns). Peak CK, peak CKMB, peak LDH, and peak GOT release were significantly lower in the Off-Pump CABG group compared with the On-Pump CABG group. Graft patency rates were similar in both groups (98 0n Off-Pump CABG vs 98 0n On-Pump CABG). The total cost for surgery and patient care was significantly lower (p<0.0001) in the Off-Pump CABG group ($ 21000 ± 7000) compared with the On-Pump CABG group ($ 33000 ± 4200). Off-Pump CABG is less invasive to the myocardium, is less expensive, and has a similar efficacy in comparison with On-Pump CABG.
