Pak J Med Health Sci Jan ;12(1):411-4.

Background: Coronary artery bypass grafting improves coronary blood flow to the heart in severe coronary heart disease. According to most of studies, in spite of co–morbid illnesses often present along with obesity, an obese body mass index was not found as an independent predictor of morbidity or mortality after Coronary artery bypass grafting (CABG). Aim : To compare outcomes (complications) after Coronary artery bypass grafting (CABG) in obese and non obese patients during their hospital stay. Methods : Study was conducted at Punjab Institute of Cardiology Lahore, Cardiology and Medical units of Mayo hospital Lahore and Gulab Devi Hospital Lahore. This study was conducted from March 2015 to March 2016. Non-probability sampling technique was used to collect the data and entered on specified proforma. Sample size was 200 CABG patients. SPSS 16 was used for the data analysis. The qualitative data variables like Gender, BMI etc were presented in form of tables along with its percentage. Quantitative data were presented in form of mean +/-S.D. Results : In this study the patients mean age was 52+/-10.10 years. There were 185(92.50%) male and 30 (15%) female patients. There were 65(32.5%) normal weight patients, 36(18%) overweight and 110(55.5%) obese patients. For CPB time the mean was 1.11+/-3.958 hours, ranging from 180 minutes with minimum to 45 minutes and maximum 250 minutes. For Cross Clamp time, mean was determined as 50.41+/-3.07, the range was 100 minutes with minimum of 15 minutes and maximum of 99 minutes. The mean duration of ventilator support was observed as 8.89+/-6.11 hours; the range was 41 hours with minimum of 2 hours and maximum of 46 hours. Mean duration of ICU stay was determined as 8.99+/-3.99 days; the range was 25 days with minimum duration of 3 days and maximum for 29 days. Sternal wound infection was found in 12(6%) patients. Conclusion: In outcomes of CABG, mean for ventilator support was 8.89+/-6.11 hours; mean for ICU stay was 8.99+/-3.99 days. 12 patients got sternal wound infection, 22 patients have atrial fibrillation, 15 patients have stroke.
