Summary

This study looks at whether certain blood markers can identify people without significant coronary artery disease, avoiding the need for more invasive tests. Researchers will enroll 1000 adults referred for a CT scan of the heart. The goal is to see if these biomarkers can accurately rule out blockages.

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 simple blood test to rule out significant coronary artery disease, reducing the need for invasive procedures.
What could go wrong
This is an observational diagnostic study, not a treatment trial. The biomarkers may not be accurate enough to replace current methods, and results may not apply to all populations.
