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 Results may not be published yet.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

Summary

This study examines plaques removed from the carotid arteries of about 3,500 people during surgery, along with imaging scans and blood samples, to find features that make some plaques prone to rupture and cause heart attacks or strokes. Researchers will track participants over several years to see who later experiences cardiovascular events. The goal is to develop better ways to identify high-risk plaques early and prevent those events.

What this could mean

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

What this could lead to
If this research succeeds, it could lead to better ways to identify people at risk of heart attacks or strokes before those events happen, and possibly point to new treatments to stabilize dangerous plaques.
What could go wrong
This is an observational study, so it will not test a new treatment directly. The findings may take years to translate into practical tests or therapies, and the markers they find may not prove reliable in larger, more diverse groups.
