Abstract :

Background: Extremely lower and extremely high body mass index (BMI) has been discussed as substantial risk factors for postoperative pulmonary complications and reduced functional capacity after cardiac surgery. The exact relationship between BMI and reduced functional capacity has not yet been defined. Objective: To find out the relationship between BMI and functional exercise capacity measured by 6MWD following coronary artery bypass graft (CABG). Methods: Patients posted for CABG were divided in to 4 groups based on the BMI. After the surgery Phase I cardiac rehabilitation was administered; the six minute walk test (6MWT) was performed preoperatively and on the 7th postoperative day. Results: The distance walked during 6MWT was significantly reduced postoperatively in all the groups (P=.000). When multiple comparisons were done, the underweight subjects fared significantly worse when compared with the other groups. (P= .000). Conclusion: There is marked reduction in functional exercise capacity following CABG. The most marked reduction was seen in the underweight group followed by the obese group.
