Brief Summary:
This is a prospective, multi-center, single-arm study enrolling adult patients who have been hospitalized for heart failure and subsequently discharged. For the duration of study participation, patients will obtain daily at-home bioimpedance measurements. Heart failure symptoms, medications, and re-hospitalizations will be tracked. Additionally, quality of life questionnaires will be administered at the beginning and end of study participation.
