Abstract
Gender has been reported to be an independent risk factor for coronary artery bypass grafting (CABG) cardiac risk evaluation. The effect of the body size on the CABG outcome is less clear. There is ongoing debate about obesity as a risk factor for adverse outcomes after cardiovascular procedures. In sixty patients with high body mass index (BMI) ( > 35) subjected to isolated CABG surgery (30 males, 30 females) aged 35 - 65 years, with coronary atherosclerosis all sixty were studied for early postoperative mortality and early outcome. The females study group showed significantly higher mortality (20%) compared to the males study group (0%) with a p value of 0.010. And also showed significantly longer hospital stay (29.8 ± 42.48) compared to the males study group (13.4 ± 5.05) with a p value of 0.040. Gender can be considered an independent risk factor for mortality and postoperative stay in morbidly obese patients undergoing CABG operation
