Postoperative Complication in Overweight Patients Undergoing Coronary Artery Bypass Graft Surgery

Abstract

This prospective observational study was conducted in National Heart Institute of Egypt. 98 patients with multi-vessel CAD indicated for CABG were included in the study, and divided into two groups: ● Group I: (53) patients with BMI over 30. ● Group II: (45) patient with BMI under 30. Patients with HBA1C above 7.5, combined CABG with other cardiac procedures, emergency CABG patients , redo patients with IHD, patients with heart failure , renal and hepatic patients were excluded from the study. Preoperative coronary angiography (CA) for both groups was studied for number, and site of diseased vessels. Conventional general anathesia, standard median sternotomy, standard cardiopulmonary bypass. In our study , we found that there is no difference between group 1(obese patients)and group2(non obese) in age and sex and other co-morbidities like diabetes and hypertension On analysis we found that obesity increases the risk of wound infections and mediastinitis. We found no increased risk of any other form of morbidity like chest infection, hepatic impairment, renal impairment or cardiovascular stroke among obese patients undergoing myocardial revascularization compared to non-obese patients.
