Influence of Complete Revascularization on Long-term Survival after Coronary Artery Bypass Surgery

To evaluate the influence of complete coronary revascularization after coronary artery bypass grafting (CABG) on long-term survival, we reviewed the records, including reports of coronary angiography, of 198 patients (25 women). Coronary artery bypass grafting was performed in the period 1973-1982, when the patients' mean age was 52.5 years. No significant (p < 0.05) difference in survival in the first 15 postoperative years was found between the patients judged to have complete revascularization at coronary angiography 6 months after CABG and the general Danish population. Complete revascularization by extensive grafting should improve survival of patients treated for angina. If the revascularization remains complete at coronary angiography assessment 6 months postoperatively, the 15-year survival rate can be expected to equal that in the general population.
