Impact of obesity on early cardiac surgical outcomes in Egypt׃ Early outcomes of coronary artery bypass graft surgery

Background

Obesity is a great burden in developing countries as Egypt due to limited resources of health care services. More than one third of Egyptians are obese. Coronary artery bypass graft surgery (CABG) is necessary for many of them. The objective of this study was to investigate the association between obesity and post-CABG morbidity and mortality in Egyptian patients.

Methods

This prospective study was conducted on 162 patients indicated for isolated CABG in Zagazig Univeristy Hospitals and El Ahrar Hospital. The patients were classified into two groups according to Body mass index (BMI) ≥ 30 (obese, group 1, n = 81) and BMI˂ < 30 (non-obese, group 2, n = 81). In-hospital and after 6 months morbidity and mortality rates were compared between both groups.

Results

A total of 162 patients (35 females) with a mean age of 54 ± 8.5 years (range = 33–70 years), mean BMI of group 1 and group 2, (34.2 ± 3.9) and (26.5 ± 1.9) respectively with range = 23–44.4 were included. Saphenous vein harvest (SVH) site infection, intensive care unit (ICU) and in-hospital stay were significantly increased in patients with BMI ≥ 30 with (p value = 0.025, 0.02, 0.04) respectively.

Conclusions

Obesity is associated with SVH site infection and long ICU and in-hospital stays but not associated with other morbidity or mortality by the sixth post-operative month.
