Abstract
Background: The aim of this study was to quantify the effect of obesity on
early results after coronary artery bypass grafting (CABG). Methods: A retrospective
cohort study of patients underwent isolated CABG from January
2000 through December 2012 was conducted. 586 patients were classified into
two groups: Obese (n = 100) BMI ≥ 30 kg/m2 and non-obese (n = 486) BMI ≤
30kg/m2
. Results: The obese patients included more women (p < 0.01), hypertensives
(p = 0.01) and dyslipidemics (p = 0001). The CPB, aortic champ
times and number of bypass graft were similar between the groups (p = 0.35, p
= 0.51 and p = 0.59 respectively). Also the composite of in-hospital mortality
and postoperative complication didn’t differ between the groups. The incidence
of perioperative myocardial infarction, and need for inotropic drugs or
IABP were significantly less in obese patients (p = 0.028, p = 0.031 and p <
0.01 respectively). Conclusions: The current study showed that obesity is not a
risk factor of adverse events after CABG and continuous to give another aspect
of the “obesity paradox”
