title: Efficacy of off-pump coronary artery bypass grafting for the patients on chronic hemodialysis.
abstract: OBJECTIVE
  Coronary artery bypass grafting (CABG) under a beating heart is reported to be less invasive and promise earlier recovery. This study was performed to evaluate the efficacy of off-pump CABG in patients with end-stage renal failure.
  
  
  METHODS
  Isolated CABG was performed on 40 hemodialysis patients at Shin-Tokyo Hospital Group between September 1, 1993, and December 31, 2000. Among them, off-pump CABG was performed in 16 and on-pump CABG in 24. Their preoperative, perioperative, and follow-up data were retrospectively collected.
  
  
  RESULTS
  Patient's demographics and coronary risk factors were similar in off-pump and on-pump groups. The mean number of bypass grafts was 1.9 +/- 1.1 in the off-pump group and 2.8 +/- 1.1 in the on-pump group (P < 0.05). Blood transfusion was significantly less frequent in the off-pump group than in on-pump group. Postoperative complications were more frequently observed in the on-pump group (7.1% off-pump vs 25.0% on-pump). There were two hospital deaths in the on-pump group and none in the off-pump group. Postoperative intubation time, ICU stay, and hospital stay were significantly shorter in the off-pump group than in the on-pump group. Although follow-up period was short (1.1 +/- 0.7 years), no cardiac events occurred in the off-pump group.
  
  
  CONCLUSIONS
  Off-pump CABG for hemodialysis patients is safe and useful and it enables early recovery. Postoperative cardiac events were controlled effectively during the short period of follow-up.
