CABG indicates coronary artery bypass graft surgery. Low risk indicates lesions with <50% stenosis, 1‐ or 2‐vessel disease. High risk indicates 2‐vessel disease with proximal left anterior descending artery or left main artery disease, 3‐vessel disease or left main artery disease.
Subgroup significantly different from the normal BMI group (P<0.05).
