Intentional Weight Loss in Overweight and Obese Patients with Heart Failure: A Systematic Review

Eur J Heart FailPublished

  • Systematic review

Authors' conclusion

All forms of weight loss intervention studied in this review were likely to result in significant weight loss, improved symptoms and QOL.

Study context

Population
Overweight and obese patients with heart failure (HF) (HF patients with obesity (HFpwO))
Participants
22 studies
Comparison
Intentional weight loss interventions in HF patients with obesity
  • Lifestyle interventionn = 9
  • Pharmacotherapyn = 3
  • Bariatric surgeryn = 10

Pooled result

As reported in the abstract

Weight loss, symptoms, QOL, LVEF and adverse events by intervention type
  • Semaglutide (1 randomized controlled trial (RCT), HF with preserved ejection fraction (HFpEF)): weight loss with improvement in quality of life (QOL)
  • Lifestyle intervention: weight loss, minimal adverse events and improved symptoms in HF with reduced ejection fraction (HFrEF) and HFpEF
  • Bariatric surgery (6 observational studies, HFrEF): weight loss and improved left ventricular ejection fraction (LVEF) safely in most patients; some developed worsening HF perioperatively
  • all studies moderate to high risk of bias except one RCT

Safety

Worsening HF after bariatric surgery · perioperatively

Bariatric surgery safe in most HFrEF patients but some developed worsening HF perioperatively
  • 6 observational studies
