Heart scan study: family history may reveal hidden plaque risk
NCT ID NCT07172308
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study used cardiac CT scans to compare the amount of high-risk plaque in the coronary arteries of 480 people with and without a family history of coronary artery disease. All participants had no prior heart problems. The goal was to see if those with a family history have more dangerous plaque, which could help guide earlier prevention.
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 it shows more high-risk plaque in those with a family history, it could support using heart CT scans for earlier prevention in that group.
- What could go wrong
- This is a small, completed observational study, not a treatment trial. It only looks at images, not future heart attacks, so the real benefit is uncertain.
