Telemonitoring to Optimize Medication Titration for Heart Failure: a Feasibility Study

A commercially available smart watch capable of continuous monitoring of heart rate and activities including daily steps count and daily activity level, detection of arrythmia using a proprietary FDA approved algorithm14, and measuring peripheral capillary oxygen saturation will be provided to the patient. Patients will be encouraged to wear the watch as often as possible during daytime and during sleep. Data gathered will be automatically transmitted wirelessly to a cloud-based platform provided by the manufacturer accessible only by the research team and the patient.

An electronic scale which measures bioimpedance using bioelectrical analysis from foot-to-foot impedance and body fluid percentage (BF%) using a proprietary equation15,16 will be provided to the patients. Patient will be encouraged to measure their bodyweight (BW) and bioimpedance twice per day, one in the morning, and one before bath, with minimal clothing. Both data will be automatically transmitted wirelessly to a cloud-based platform provided by the manufacturer accessible only by the research team and the patients.

An electronic cuffed arm blood pressure monitor will be provided to the patient with instruction on how to perform proper blood pressure measurement at home16. Patients are encouraged to take at least 2 blood pressure reading daily, one in the morning and one in the evening. Blood pressure reading will be transmitted wirelessly to an online platform provided by the manufacturer accessible only by the research team and the patients.

a mobile Application through which data from remote monitoring and wearables will be incorporated, and instruction for medication titration and education on heart failure management will be provided to the patients.
