What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study tested whether the Corsano CardioWatch 287-2, a smartwatch that measures blood pressure using light sensors, can accurately track blood pressure changes in people starting or adjusting their blood pressure medication. Eighty adults with uncontrolled high blood pressure wore the watch for 28 days while also using a standard arm cuff for comparison. The goal was to see if the watch could reliably measure the drop in blood pressure after treatment changes, potentially enabling remote monitoring at home.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Corsano CardioWatch 287-2 (a smartwatch that measures blood pressure using light sensors)
What this could lead to
If successful, this could show that a smartwatch can reliably monitor blood pressure at home, potentially reducing the need for frequent clinic visits.
What could go wrong
This is a small, completed study (80 people) that only checks accuracy over 28 days. The device may not be as precise as a standard cuff, and results may not apply to all patients or long-term use.
