Brief Summary

To conduct a prospective, observational study to evaluate the non-interventional feasibility of using heart sounds measurements recorded by the LifeVest® Wearable Cardioverter Defibrillator (WCD) for monitoring clinical evidence of heart failure decompensation.

Detailed Description

To conduct a prospective, observational study to evaluate the non-interventional feasibility of using heart sounds measurements recorded by the LifeVest® Wearable Cardioverter Defibrillator (WCD) for monitoring clinical evidence of heart failure decompensation.

Participants will be adult (age ≥ 18 years) heart failure patients with an ejection fraction (EF) ≤ 35% and eligible to wear the WCD for at least 3 months.

An FDA-approved WCD will be prescribed for at least 3 months of use after hospital discharge.

This is a multi-center, prospective, observational study.

The study will enroll a total of 300 subjects, anticipating that at least 250 subjects will complete the study. A maximum of 50 sites will enroll patients into the study.
