Coronary artery disease as a definitive risk factor of short-term outcome after starting hemodialysis in diabetic renal failure patients.
Cardiovascular disease is a major cause of morbidity and mortality in patients with diabetes who are receiving dialysis. It is known that cardiac mortality is high in the first year of hemodialysis (HD). The purpose of this study was to clarify the prevalence of coronary artery disease (CAD) in patients with diabetes at the initiation of HD, and to investigate the relationship between short-term outcomes after starting hemodialysis and CAD. We performed coronary angiography (CAG), whether or not patient had angina, within one month of initiation of maintenance HD in 17 of 34 consecutive unselected diabetic patients. We studied the two-year survival rate of those with CAD. Eleven patients (65%) were classified CAD-positive. Nine (82%) of these 11 had multivessel disease. Clinical and hematologic factors did not differ significantly between the groups with and without CAD. During the two-year follow-up period, 28 (82%) of 34 patients survived. In patients with CAD the two-year survival rate was 60%. None of the patients without CAD died within 2 years after starting HD. These results suggest that the presence of CAD at the initiation of HD may play a critical role in short-term outcomes after starting HD. We believe that an evaluation of CAD should be performed at the initiation of HD.
