ABSTRACT
@#ObjectiveTo investigate the relation between body mass index(BMI) and postoperative complications after coronary artery bypass grafting (CABG).MethodsThe clinical data of 99 patients who underwent CABG at Fujian Provincial Hospital were analyzed. The patients were divided into three groups according to their preoperative BMI: normal group(n=21), overweight group(n=33), and obese group(n=45). And the related observation indexes were compared among the 3 groups.ResultsThe hospital mortality of normal, overweight and obese groups were 0%, 3.03% and 4.44% respectively (P>0.05). The rate of pulmonary infection (24.44%) or wound infection (24.39%) in the obese group was significantly higher than those in the normal group(4.76% or 0%) (P<0.05). The time stay ICU or hospital in the obese group were significantly greater than those in the normal and overweight groups (P<0.05). 6-minute walking test (6MWT) in the obese group was significantly less than that in the normal and overweight groups 3 months after the operation(P<0.001).ConclusionHigh preoperative BMI can take a negative effect on patients after CABG following postoperative complications.
