This study is being done to find out if we can better monitor subjects with heart failure with the use of a wearable device (called SimpleSense garment) that can monitor multiple factors of heart failure that affect the body such as heart rate, activity, heart rhythm, and respiratory rate. Participants will wear the SimpleSense garment for 90 days for at least 12 hours daily. Participation in the study will include two research clinic visits and 2 phone calls over 4 months. Participants will be compensated for time and travel.
Risks of this study include loss of confidentiality, blood draw and skin irritation from wearing the garment.
