BACKGROUND: Obesity surgery reduces the incidence of long-term cardiovascular events by modifying the associated risk factors. The derived benefits of weight loss surgery might be counterbalanced by the increased cardiovascular risks in some patients. The primary objective of the present study was to determine the rate of cardiovascular events after obesity surgery in patients considered to have an increased cardiac risk profile at a tertiary referral hospital. METHODS: A retrospective analysis of the data from consecutive patients who underwent obesity surgery at the Cleveland Clinic Florida was performed. The use of beta-blockers, noninvasive stress testing, and perioperative events were assessed. RESULTS: The data from 154 patients who had undergone a preoperative cardiac consultation at the Cleveland Clinic Florida before obesity surgery from 2003 to 2006 were analyzed. Most patients were women (n = 108, 69%), and 25 (16%) were >65 years old. The number of patients who received perioperative beta-blockers was 72 (47%). Noninvasive stress testing was performed in 78 patients (50%). Of the 78 patients who underwent noninvasive stress testing, 25 (32%) had a positive finding. Only 1 patient with positive stress test results had an obstructive coronary artery lesion found on cardiac catheterization. A total of 5 nonfatal cardiac-related events (3.2%) occurred. The in-hospital mortality rate was 0%. CONCLUSION: Obesity surgery in patients with established coronary heart disease or risk factors is a safe and well-tolerated procedure, with an overall low rate of cardiac events. Noninvasive stress testing in this population resulted in a high rate of false-positive results and uncommonly led to intervention.
