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”.
