Overview
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.
