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 This study
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
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 tests whether a Huawei smartwatch can accurately identify adults at risk for hypertension (high blood pressure) in everyday settings. About 500 adults in Malaysia will wear the smartwatch, which uses light sensors to estimate blood pressure. A subgroup of about 50 people flagged as high-risk will then undergo 24-hour ambulatory blood pressure monitoring, the gold standard, to confirm the smartwatch's accuracy. The goal is to see if wearable technology can support early detection of undiagnosed hypertension in the community.

What this could mean

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

Active substance
Huawei smartwatch using photoplethysmography (PPG) technology to estimate blood pressure
What this could lead to
If the smartwatch proves accurate, it could enable widespread, low-cost screening for undiagnosed hypertension, helping prevent heart disease and stroke.
What could go wrong
The trial is relatively small and early, and smartwatch readings may not match clinical accuracy. False alarms or missed cases could limit its real-world usefulness.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

Community-based sample of multi-ethnic Malaysian adults aged 18 years and older. Participants are recruited across Malaysia using digital advertisements via the Huawei Research Platform app, Sunway University community outreach programs, health screening events, corporate wellness initiatives, social media, and primary care clinic referrals. The population includes individuals with compatible smartphones who are willing to wear monitoring devices continuously to assess hypertension risk.
