We examined the results of coronary artery bypass grafting (CABG) in patients with end-stage renal disease and symptomatic ischemic heart disease who had significant arteriosclerotic narrowing of one or more coronary vessels between 1970 and 1984. Twenty-four such patients underwent bypass grafting, 20 dialysis patients and four who had been transplanted. Bypass grafting completely or partially relieved symptoms in 83%. The hospital mortality associated with this surgery for the 20 dialysis patients was 20% compared with a lower overall hospital mortality for bypass grafting in nondialysis patients of 1.3%. Greater hospital mortality was noted for patients over age 60 undergoing bypass grafting, 33.3% v 1.9% in nondialysis patients. In this study, the most significant factor associated with mortality was older age. We conclude that bypass grafting has an acceptable mortality in younger end-stage renal disease patients anticipating or having had renal transplantation, but it is associated with a high hospital mortality in older dialysis patients. © 1988, National Kidney Foundation, Inc..
