CT-Guided heart exams could cut radiation and time
NCT ID NCT05218694
First seen Aug 26, 2026 · Last updated Aug 27, 2026 · Updated 1 time
Summary
This trial tests whether using detailed CT images of the heart's arteries to plan invasive procedures can reduce radiation exposure, procedure time, contrast use, and tools needed. Adults with stable angina and significant blockages are randomly assigned to receive either standard care or a CT-guided approach. The goal is to see if this smarter planning makes the procedure more efficient and potentially safer.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- CCTA-guided focused coronary angiography examination
- What this could lead to
- If effective, this approach could make heart procedures faster, safer, and less resource-intensive.
- What could go wrong
- The trial is relatively small and early, so benefits may not be confirmed or widely applicable.
