Evaluation of cardiovascular risk for renal transplantation in diabetic patients.
Cardiovascular disease contributes in a major way to morbidity and mortality in diabetic patients with end-stage renal disease. Sixty patients with type I diabetes were evaluated prior to renal transplantation to determine the risk of cardiovascular complications. On the basis of results of thallium stress testing and/or cardiac catheterization, each patient was assigned to one of five categories. There were no cardiovascular events in the seven patients who had negative results on stress testing. Of the remaining 53 patients, all of whom underwent cardiac catheterization, 30 had normal coronary arteries. None of these 30 patients had any cardiac morbidity, and the two deaths that occurred in this group were not attributable to cardiac causes. Significant coronary artery disease was present in 38 percent of the patients. The overall mortality rate was 5.4 percent in those patients without coronary artery disease and 43.5 percent in those with the disease. In addition, the mortality rate in patients with coronary disease classified as severe was 62 percent, whereas it was 20 percent in those categorized as having moderate disease. The data indicate that patients with diabetes and end-stage renal disease who are at highest risk for cardiovascular events can be identified, and these patients probably should not undergo renal transplantation.
