New sensor could help doctors drain fluid from heart failure Patients' lungs
NCT ID NCT07600398
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests whether a wearable sensor that measures lung fluid can help doctors better treat fluid buildup in patients hospitalized for acute heart failure. About 216 adults will be randomly assigned to either standard care or care guided by the sensor. The goal is to see if the sensor-guided approach reduces the risk of death, rehospitalization, or urgent heart failure visits within 30 days after discharge.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Remote Dielectric Sensing (ReDS) device
- What this could lead to
- If it works, this could give doctors a simple, non-invasive tool to better manage fluid levels in heart failure patients, potentially reducing hospital readmissions.
- What could go wrong
- This is a relatively small, early-stage trial (216 participants) testing a device, not a drug. The benefit may be modest or not statistically significant, and results may not apply to all heart failure patients.
