The Manage HF study is a multicenter 12-week randomized controlled double-blind 2x2 factorial clinical trial. This study will investigate the effectiveness of two contextual just-in-time adaptive interventions (JITAIs) delivered via a mobile app for heart failure patients. The clinical worsening intervention targets self-management of behaviors to prevent worsening of a patient's heart failure symptoms. The dietary sodium intervention promotes lower sodium intake. Eligible participants will be randomized to the dietary sodium intervention, the clinical worsening intervention, both interventions, or no intervention in a 1:1:1:1 manner, stratified by site, gender, and HF type (HFpEF versus HFrEF).
