Early Outcome of Coronary Artery Bypass Grafting in Obese and Non Obese Patients

Objective: To determine the impact of body mass index (BMI) on short-term outcomes like; renal failure, prolonged ventilation and mortality after CABG surgery. Methodology: This prospective comparative study was conducted at the Cardiac Surgery Department, Pervaiz Elahi Institute of Cardiology, Bahawalpur from February to December 2021. A total of 148 patients were enrolled after taking written consent and data was collected through predesign proforma sheets, including; clinical history, investigation and early outcomes in term of (renal failure, prolonged ventilation, and mortality). SPSS 23 was used to analyze data with statistically significant p-value < 0.05. Results: The findings showed that average age of research participants were 57.14 ± 3.07 (age range 30-73 years) and 121 (81.76%) male compared with 27(18.24%) female patients were enrolled with insignificant p-value of 0.730. In this study prolonged ventilation was found in 5(6.76%) obese and 8(10.81%) non-obese patients with insignificant p-value of 0.070. Renal Failure was found in 2 (2.70%) obese and 8 (10.81%) non-obese patients with significant p-value of 0.02 and mortality in 4(5.41%) obese and 2 (2.70%) non-obese patients with significant p-value of 0.0482. Conclusion: The results of the current investigation demonstrated that an obese BMI was a reliable indicator of morbidity or mortality following CABG.
