Patients with end‐stage renal disease carry a risk of coronary atherosclerosis. This study was performed to evaluate the perioperative and remote data of coronary artery bypass grafting (CABG) in hemodialysis dependent patients. We retrospectively analyzed the results of isolated CABG performed at Shin‐Tokyo Hospital between June 1, 1993 and May 31, 2000. Preoperative, perioperative, and follow‐up data of the patients on hemodialysis (Group HD, n = 37) were collected and compared with those of control patients (Group C, n = 1,639). Group HD consisted of 26 males and 11 females with a mean age of 59.9 ± 8.1 years, and the mean number of bypasses was 2.5 ± 1.1. Group HD had a longer postoperative intubation time, ICU stay, and hospital stay than Group C. The postoperative major complication rate in Group HD (18.9%) was not significantly different from that in Group C (11.3%). However, the inhospital mortality rate in Group HD (5.4%) was higher than Group C (0.6%). At the mean follow‐up of 2.4 years, the actuarial 3‐year survival of Groups HD and C were 90.6% and 97.6%, respectively (p < 0.001), excluding hospital mortality. The actuarial 3‐year cardiac event‐free rates were 84.3% in Group HD and 88.8% in Group C, showing no difference. Patients on chronic hemodialysis carry a significant risk of prolonged inhospital care and hospital death. Once successful surgical revascularization was completed, their long‐term cardiac events could be controlled as effectively. The increased distant death rates was probably associated with the nature of renal disease.
