New heart test could predict future attacks
NCT ID NCT06890013
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at a new technology called Cor-IS that measures how well blood vessels widen (flow mediated dilation) in people who have had a heart attack. Researchers will compare it to the standard FMD test and track patients for future heart problems. The goal is to see if Cor-IS can better predict who is at risk for another heart attack or stroke.
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 successful, this could lead to a simpler, more accurate way to assess heart health after a heart attack, helping doctors better predict and prevent future events.
- What could go wrong
- This is an early observational study with only 100 participants, so results may not apply to everyone. The new method may not prove better than existing tests.
