SUMMARY
There is increasing evidence that cardiopulmonary bypass (CPB) may be responsible for the morbidity associated with coronary artery bypass grafting (CABG) surgery. Recent developments in cardiac stabilization devices have made CABG without CPB feasible. However, there is conflicting evidence to date from published trials comparing outcomes between CABG performed with and without CPB.
In this study, eighty low-risk ischemic heart disease patients with multivessel disease were included.
The patients were divided into two groups:
• Group I: Included forty patients who underwent on-pump CABG.
• Group II: Included forty patients who underwent off-pump CABG.
There was no statistically significant difference between the two groups preoperatively regarding their age, sex, Canadian cardiovascular angina classification, comorbidities, and ejection fraction.
Regarding Intraoperative comparison, there was a significant difference in the total operation time where in group II it was significantly less , on the other hand, in group I the total number of grafts and the mean per patient were higher with no statistical significant difference.
Regarding early postoperative comparison in the intensive care unit, there was a significant difference in the ventilation time and the ICU stay which were shorter in group II. Also, the total blood loss and blood transfusion were less in group II.
Regarding postoperative ejection fraction, there was marked increase in both groups. There was a significant difference in the same patient group regarding preoperative and postoperative ejection fraction, but there was no statistically significant difference between the two groups.
The postoperative complications of both groups showed no statistically significant difference.
