Prognosis after off-pump coronary artery bypass in patients receiving hemodialysis.
OBJECTIVE
This study was performed to evaluate the perioperative and long-term results of off-pump coronary artery bypass grafting (OPCAB) in hemodialysis (HD)-dependent patients.


METHODS
We retrospectively analyzed the results of isolated OPCAB performed at Tokyo Women's University Medical Center East from February 27, 2000, to May 12, 2006. Perioperative data for patients receiving HD (group HD, n=39) were compared with data from patients not receiving HD (group noHD, n=60). The long-term results of group HD also were examined.


RESULTS
Group HD consisted of 34 males and 5 females with a mean age of 63.2+/-10.2 years. The percentage of patients in group HD with complete all-arterial revascularization was significantly lower than in group noHD. However, the mortality rate, number of distal anastomoses, operative time, intensive care unit (ICU) stay, hospital stay, bleeding during surgery, blood transfusions, intubation time, intra-aortic balloon pumping use, and emergency ratio were similar in the two groups. During a mean follow-up of 27.0+/-13.7 months, the actuarial 1-and 5-year survival rates of group HD were 80% and 70%, respectively.


CONCLUSIONS
In patients receiving HD, OPCAB is safe and improves survival.
