Early complications and long-term survival in severely obese coronary bypass patients.
Our objective was to describe the short-term morbidity of coronary artery bypass operations and the effect of surgery plus aggressive cardiac rehabilitation on the long-term prognosis of severely obese patients with coronary artery disease. We investigated an inception cohort of 28 consecutive severely obese patients with three-vessel coronary disease followed on average for 51 months. The patients' age, preoperative and postoperative weight, risk factors, and cholesterol were measured. We performed coronary artery bypass surgery, then began aggressive cardiac rehabilitation programs. We recorded intraoperative data, perioperative deaths, complications, readmissions, and lengths of stay. Also, New York Heart classifications and use of anti-anginal or cholesterol-lowering medications were noted. All patients were followed up. Despite high morbidity, long-term function and survival of severely obese CABG patients compares favorably with that of average patients. However, aggressive behavior modification fails to alter their postoperative weight or risk profile, placing them at risk for both second CABG procedures and continued obesity-related disease occurrences.
