Using a wearable device to monitor congestion in heart failure patients during exercise

Correlation of the Non-invasive Cardiopulmonary Management Wearable Device With Measures of Congestion in Heart Failure in Exercise - CONGEST - HF - EX

Observational NHS Greater Glasgow and Clyde · NCT06393842

This study is testing a wearable device to see if it can help heart failure patients and those on dialysis monitor fluid buildup during exercise to prevent hospital visits.

What this trial studies

This observational study aims to evaluate the correlation between a non-invasive cardiopulmonary management wearable device and various measures of congestion in patients with heart failure. The study will involve two cohorts: one consisting of patients on hemodialysis and the other comprising heart failure patients requiring intravenous diuretics. By monitoring fluid status and congestion, the study seeks to identify early signs of decompensation, potentially allowing for timely interventions to prevent hospitalizations. The methodology includes the use of the wearable device alongside biochemical markers and non-invasive measures to assess congestion levels.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older with established heart failure or those on hemodialysis requiring significant fluid removal.

Not a fit: Patients with cognitive impairments, severe lung disease, or significant skin conditions at the device application site may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to earlier interventions for heart failure patients, reducing hospitalizations and improving patient outcomes.

How similar studies have performed: While the use of wearable devices in monitoring heart failure is a growing field, this specific approach is novel and has not been extensively tested in prior studies.
