This research investigates how weight loss through a diet management mobile app and an intelligent weight scale affects cardiovascular health in obese patients with heart failure. The study focuses on patients with heart failure with reduced ejection fraction and aims to see if these tools can reduce death rates, hospital stays related to heart failure, and improve frailty and quality of life. The trial addresses a gap where current heart failure guidelines recognize obesity as a risk but lack effective interventions for this group. Participants are randomly assigned to one of two groups: one group uses a fully functional diet management app and intelligent weight scale designed to support weight loss in obese heart failure patients, while the other group uses limited-function versions of the app and scale as a comparison. Both groups use the app at every meal and the scale daily for 12 months. The trial is a multicenter, single-blind randomized controlled study. During the study, participants will visit the clinic after 12 months for checkups. Researchers will collect data on a composite cardiovascular outcome, including all-cause mortality and hospitalizations related to heart failure, tracked over one year. Adherence to app and scale use is monitored through the mobile application. The study measures the impact on heart failure frailty, quality of life, and overall cardiovascular outcomes over the trial period.
