Purpose

The ENGAGE-HF mobile application tracks three key features over time: (1) heart failure health status, (2) vital signs (e.g., blood pressure, heart rate) and weight, and (3) the quality of heart failure medication therapy. Helping patients understand how these characteristics interact and change over time may improve their ability to understand and manage heart failure. In this study, the investigators aim to evaluate whether the ENGAGE-HF mobile application, by facilitating the behavior change strategies of self-monitoring and feedback, and a clinician-facing dashboard, improves the optimization of heart failure guideline-directed medical therapies (GDMT) and quality of life. An optional sub-study of cognitive function will invite all eligible participants enrolled in the main study to participate.
