Voice-based Outcome Identification and Clinical Evaluation in Heart Failure

VOICE-HF is a clinical study designed to evaluate the performance of a novel non-invasive software device (Noah Labs Vox) that uses vocal characteristics to estimate DHF risk and has strong potential for clinical success. This study will compare the performance of Noah Labs Vox with the contemporary performance of commonly used weight-based remote monitoring rules and applications to determine efficacy and safety.

Inclusion Criteria: * Age ≥22 * HF diagnosis (Stage C) * DHF event within prior 180 days Exclusion Criteria: * Monitoring with implantable volume or pressure monitoring devices, or * Planned cardiac surgery or major intervention (e.g., LVAD or transplant), or * Otherwise inability or unwillingness to comply with study procedures.
