Mobile Applet for Weight Management in Obese Heart Failure Patients

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.
