Has the Time Come to Be More Aggressive With Bariatric Surgery in Obese Patients With Chronic Systolic Heart Failure?

purpose of reviewObesity is a strong risk factor for the development of heart failure (HF). Diet, exercise, and weight-loss pharmacotherapies have limited potential to achieve significant and sustainable weight loss, especially in patients with symptomatic systolic HF. This review seeks to determine the role of bariatric surgery for patients with systolic HF and obesity. RECENT

findingsBariatric surgeries such as the laparoscopic sleeve gastrectomy (LSG) and Roux-en-Y gastric bypass (RYGB) represent the most successful long-term strategy for achieving weight loss and diabetes and hypertension remission in the general obese population. These benefits translate to reductions in cardiovascular events and mortality, as well as improvements in myocardial structure and function. There is also now data supporting the safety of LSG or RYGB in patients with systolic dysfunction and a reduction in HF admissions post-operatively. Current literature and clinical experience suggest that the most appropriate bariatric surgery candidates with HF are patients aged < 50-60 years, with severely depressed systolic function and NYHA II-III symptoms, who have failed non-surgical strategies and have a high likelihood of future cardiac transplantation candidacy after weight loss. This review seeks to determine the role of bariatric surgery for patients with systolic HF and obesity.
