Key result
Bariatric surgery in patients with comorbid obesity and heart failure is associated with significant weight loss, improved left ventricular ejection fraction, and enhanced functional capacity.
Why the study?
Heart failure risk increases dramatically in obese individuals, prompting the need to explore interconnecting physiologic mechanisms and weight loss treatment strategies focusing on bariatric surgery.
Does bariatric surgery improve cardiac function and symptoms in patients with obesity and heart failure?
Does bariatric surgery improve cardiac function and symptoms in patients with obesity and heart failure?
Bariatric surgery appears to be an effective intervention for weight loss in patients with obesity and heart failure, leading to improvements in left ventricular ejection fraction and functional status.
May support bariatric surgery in obese HF; hypothesis-generating from Level 5 data and needs RCTs before practice change.
Obesity is a growing worldwide epidemic with significant economic burden that carries with it impacts on every physiologic system including the cardiovascular system. Specifically, the risk of heart failure has been shown to increase dramatically in obese individuals. The purpose of this review is to provide background on the individual burdens of heart failure and obesity, followed by exploring proposed physiologic mechanisms that interconnect these conditions, and furthermore introduce treatment strategies for weight loss focusing on bariatric surgery. Review of the existing literature on patients with obesity and heart failure who have undergone bariatric surgery is presented, compared, and contrasted.

Datta et al. (2021) conducted a review in Heart failure and obesity. Bariatric surgery vs. Non-surgical management or pre-operative baseline was evaluated. Bariatric surgery in patients with comorbid obesity and heart failure is associated with significant weight loss, improved left ventricular ejection fraction, and enhanced functional capacity.
