Abstract
The global burden of obesity is on a rising trend and is a major aetiopathogenic factor for non-communicable diseases, prevalence of obesity-related complications including cardiovascular risk factors such as diabetes, hypertension and dyslipidemia. But numerous studies have documented an obesity paradox in which overweight and obese people with cardiovascular disease have a better prognosis compared with patients with normal body mass index (BMI). This prospective observational study aims to evaluate the effects of obesity on early post-operative outcomes after coronary artery bypass grafting (CABG). This is a prospective study, which includes total 100 patients of multi-vessel CAD who has undergone elective CABG. These patients have been divided in two groups: Group I with 54 patients having BMI> 30 and Group II with 46 patients having BMI< 30. Aim- This study aims to evaluate the effects of obesity on the early post-operative outcomes following CABG like post-operative ventilation time, duration of ICU and hospital stay, improvement in ejection fraction, wound infection, CVA, renal impairment, hepatic insufficiency and mortality. Result: Our study demonstrated a significantly prolonged duration of hospital stay and increased wound infection rates in obese patients, but no statistically significant difference in other parameters between the two groups.
