Summary

This study examined how being obese (BMI over 30) affects hospital outcomes after coronary artery bypass grafting (CABG) in 500 patients with chronic ischemic heart disease. Researchers tracked death rates, neurological injury, kidney injury, breathing machine time, and need for repeat surgery. The goal was to understand risks in this specific group, not to test a new treatment.
