Can a smart ring replace the blood pressure cuff for dialysis patients?
NCT ID NCT07753876
First seen Aug 10, 2026 · Last updated Aug 25, 2026 · Updated 3 times
Summary
This study tests whether a ring-shaped, cuffless device called CART BP Pro can accurately measure blood pressure in people receiving maintenance hemodialysis. Participants will wear the device on their finger for about 48 hours, and its readings will be compared with standard blood pressure measurements. The study also looks at whether the device's readings are consistent over time and whether they relate to heart health indicators. The goal is to see if this wearable could offer a more convenient and continuous way to monitor blood pressure in this population.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- CART BP Pro, a cuffless ring-type blood pressure monitoring device worn on the finger
- What this could lead to
- If validated, this device could offer a more comfortable and continuous way to monitor blood pressure in dialysis patients, potentially improving cardiovascular risk prediction.
- What could go wrong
- The device may not match the accuracy of traditional methods, and the study is observational, so it cannot prove that using the device improves health outcomes.
