Monitoring heart failure patients through voice analysis

A Pilot Study on AI-Based Voice Analysis for Monitoring Patients Hospitalized With Acute Decompensated Heart Failure

Observational Noah Labs · NCT06566911

This study is testing if daily voice recordings from heart failure patients in the hospital can help spot signs of their condition getting worse.

What this trial studies

This observational study focuses on patients with acutely decompensated heart failure at two sites in the United States and Germany. Participants will record their voices daily during their hospital stay, from admission to discharge, while additional clinical data such as left ventricular ejection fraction and NTpro-BNP levels will be collected. The aim is to identify voice-based indicators that could signal heart failure progression, potentially improving remote monitoring and self-management for these patients.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older who have been clinically diagnosed with acutely decompensated heart failure.

Not a fit: Patients with disabling mental diseases, chronic obstructive pulmonary disease, or those requiring intensive care treatment may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to more effective monitoring and management strategies for heart failure patients.

How similar studies have performed: While voice analysis for health monitoring is an emerging field, this specific approach in heart failure is relatively novel and has not been extensively tested in prior studies.
