Key result
Severe obesity (BMI ≥40.0) was associated with a higher risk of overall early complications (adjusted OR 1.56; 95% CI 1.21-2.01) and longer length of stay following coronary artery bypass grafting.
Why the study?
Does severe obesity increase the risk of early complications and extended length of stay in patients undergoing coronary artery bypass grafting surgery?
Population
7,560 patients who underwent coronary artery bypass grafting (CABG) surgery
Comparison
Higher body mass index categories vs Normal body mass index (BMI 18.5 to 24.9 kg/m²)
Design
Cohort
Follow-up
In-hospital

May warrant enhanced perioperative monitoring in severe obesity; leaves open whether weight optimization reduces CABG complications.
Cohort (n=7,560)
Does severe obesity increase the risk of early complications and extended length of stay in patients undergoing coronary artery bypass grafting surgery?
Odds Ratio: 1.56 (95% CI 1.21–2.01)
Severe obesity (BMI ≥35.0) is an independent risk factor for early post-surgical complications, particularly infections, and extended length of stay following CABG.
Terada et al. (2016) conducted a cohort in Coronary artery bypass grafting (n=7,560). Severe obesity (BMI ≥40.0 kg/m2) vs. Normal weight (BMI 18.5-24.9 kg/m2) was evaluated on Overall early complications (adjusted OR 1.56, 95% CI 1.21-2.01). Severe obesity (BMI ≥40.0) was associated with a higher risk of overall early complications (adjusted OR 1.56; 95% CI 1.21-2.01) and longer length of stay following coronary artery bypass grafting.
