What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
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
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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

Researchers are testing whether primary care clinics can prevent heart attacks and strokes by automatically calculating each patient's cardiovascular risk and sending monthly text messages with advice to those at high risk. The trial enrolls about 22,000 adults aged 40 to 79 in Yinzhou, China, who have no history of heart disease, stroke, or heart failure but whose 10-year risk score is 10% or higher. Clinics are randomly assigned to use the risk-based monitoring strategy or usual care, and researchers will track changes in risk factors like blood pressure and cholesterol, as well as whether fewer participants have major cardiovascular events.

What this could mean

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

Active substance
automatic cardiovascular risk scoring with monthly text-message advice
What this could lead to
If it works, this could give primary care clinics a low-cost way to flag high-risk patients and nudge them toward prevention before a heart attack or stroke happens.
What could go wrong
The strategy relies on patients acting on text messages and on clinics using the risk scores. Many prevention trials show that reminding people does not always change long-term outcomes, and the study may not prove that this approach prevents heart attacks or strokes.

Participants

About 22,032 people

The number the study aims to enrol. It can still change while the study runs.
