Relationship of Body Mass Index With Outcomes After Coronary Artery Bypass Graft Surgery

This study demonstrates that BMI is an independent predictor of mortality and morbidity after CABG surgery. Previous studies that model BMI linearly or as categories cannot accurately capture this U-shaped relationship and are unlikely to find a significant contribution by including BMI. Further research is needed to determine the mechanisms of risk for patients with low and high BMI and whether interventions to modify BMI may improve patient outcomes.
