Wristband could change how we track high blood pressure
NCT ID NCT06356077
First seen Jun 25, 2026 · Last updated Jun 26, 2026 · Updated 1 time
Summary
This completed study looked at how blood pressure changes over 12 weeks in 1,729 adults with hypertension who used the Aktiia 24/7 optical blood pressure monitor. The device is a wristband that measures blood pressure continuously without a cuff. Researchers also asked participants which monitoring method they preferred: the Aktiia bracelet, a home blood pressure monitor, or a 24-hour ambulatory monitor. The goal was to gather information, not to test a treatment.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Aktiia 24/7 optical blood pressure monitoring (OBPM) device
- What this could lead to
- If successful, this study could show that continuous optical blood pressure monitoring is a practical and preferred way to track hypertension at home.
- What could go wrong
- This is an observational study, not a treatment trial. It cannot prove that using the device improves health outcomes, and results may not apply to all people with high blood pressure.
