The Effect of Bariatric Surgery on Patients with Heart Failure: a Systematic Review and Meta-analysis

Ali Esparham et al. Obes Surg. 2023 Dec.

Abstract

The current study aims to evaluate the effect of bariatric metabolic surgery (BMS) on the New York Heart Association (NYHA) class and left ventricular ejection fraction (LVEF) in patients with diagnosed heart failure (HF). Fourteen related articles with 217 patients were included in the final analysis. LVEF significantly improved after BMS in patients with HF with a mean difference of 7.78% (CI 95%: 3.72, 11.84, I2 = 83.75, p-value < 0.001). Also, the NYHA class significantly decreased after BMS with a mean difference of - 0.40 (CI 95%: - 0.62, - 0.19, I2: 47.03, p-value < 0.001). A total of 27 patients with obesity and HF were listed for cardiac transplantation after BMS. Of those, 20 patients successfully underwent heart transplantation after BMS.
