Mobile Applet for Weight Management in Obese Heart Failure Patients

Overview

The objective of this clinical trial is to investigate the effect of weight reduction through a diet management application and an intelligent weight scale on a composite cardiovascular endpoint in obese patients with heart failure. The main questions are: Does the use of a diet management APP and intelligent weight scale reduce 1-year all-cause mortality, heart failure hospitalization, and first heart failure hospital stay? Does the use of a diet management APP and intelligent weight scale improve the outcomes of assessment of heart failure frailty and quality of life for heart failure? Researchers will compare using the fully functional diet management app and intelligent weight scale to using the limitedly functional app and intelligent weight scale to see if the app works to improve heart failure conditions. Participants will: Use the diet management app at every meal and the intelligent weight scale every day for 12 months, and visit the clinic at 12 months for checkups.

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.
