Intentional weight loss, particularly through bariatric surgery, is associated with improvements in New York Heart Association (NYHA) classification, diastolic function, and reductions in left ventricular (LV) mass index and left atrial size.
Intentional weight loss improves heart function, including diastolic function and reducing left ventricular mass and left atrial size.
ModerateSupportsMEDIUM confidence
Two recent meta-analyses of cohort studies confirmed that intentional weight loss is associated with improvements in New York Heart Association (NYHA) classification, diastolic function, reductions in left ventricular (LV) mass index, and left atrial size (20, 21).
Why this rating
Based on meta-analyses of cohort studies cited in the introduction.

- Roux-en-Y gastric bypass (RYGB) surgery is the only treatment for morbid obesity that conveys substantial and sustained weight loss and long-term remission of obesity-related comorbidities, whereas lifestyle interventions have failed to reduce cardiovascular event rates in obese patients with type 2 diabetes.Moderate
- Bariatric surgery (Roux-en-Y gastric bypass) reduces the incidence of heart failure by 2-5 times compared to non-surgical patients, as observed in large Swedish registries.Moderate
