Hunting the hidden warning signs of heart attacks and strokes
NCT ID NCT05821894
First seen Sep 08, 2026 · Last updated Sep 09, 2026 · Updated 1 time
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.
