NCT ID NCT07613853
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looks at how to best share personal heart health information to encourage healthy changes. About 1,500 people from the Dallas Heart Study will receive their results in one of two letter formats: one with simple color-coded risk categories, the other with exact numbers and a red-to-green scale. Researchers will track whether people watch educational videos and report any health changes they make after getting their results.
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 show the best way to share personal heart health information so people are more likely to take action and improve their health.
- What could go wrong
- This is a behavioral study, not a treatment trial. It tests how information is presented, not a new drug or therapy. Results may not apply to all groups or lead to lasting behavior change.
