Mobile Applet for Weight Management in Obese Heart Failure Patients

Obesity is one of the major risk factors for heart failure. Current guidelines for heart failure emphasize that severe obesity is associated with a poor prognosis in patients with heart failure, but there are no recommended effective interventions. Caloric restriction alone, increased exercise, the use of weight-loss drugs, and bariatric surgery are not appropriate for obese patients with heart failure. Whether obese heart failure patients with reduced ejection fraction (HFrEF) can benefit from weight loss treatment has not been evaluated in randomized controlled trials so far. This study combines caloric restriction with lifestyle management to help HFrEF patients lose weight.
