The HEARTFELT Study

This pragmatic randomized crossover trial looks at the effect(s) of using a remote patient monitoring device (Heartfelt device) with health alerts to monitor the development of peripheral edema in patients with heart failure (HF). The hypothesis is that this passive measurement method will lead to better data availability, which in turn will improve patient care and reduce hospitalizations for the management of worsening HF (HF hospitalizations, HFHs) in nonadherent participants with chronic HF. The study objectives are: * Primary objective: Establish if the Heartfelt device is safe to use and effective at reducing HFHs. * Secondary objectives: 1. Establish the effect of the Heartfelt device on data availability compared to existing remote monitoring devices. 2. Establish the effect of the Heartfelt device on HF clinical outcomes. Participants will need to: * Install the device in their home for at least a year and up to 4 additional years after. * Reply to remote patient monitoring phone calls to follow the care plans.
