CT scan vs. invasive test for heart artery blood flow
Part of Heart & circulation clinical trials.
This study looks at how well a special CT scan (FFR CT) matches the results of a more invasive wire test (invasive FFR) for measuring blood flow in heart arteries. It may help doctors use CT scans more confidently instead of always needing the invasive procedure.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 years or older.
- You have stable symptoms suggesting coronary artery disease (like chest pain or shortness of breath with activity).
- You have had a CT scan of your heart arteries (CTCA) and a special CT that checks blood flow (FFR CT).
- You also had a wire test during a heart catheterization (invasive FFR) to measure blood flow.

Other trials that look related to this one.
This study compares two heart-imaging tests—cardiac MRI (CMR) and CT—to see which better helps evaluate coronary artery disease in people with chest pain. You may be asked to have one of these scans as part of your heart work-up.
This trial compares two non-invasive ways to measure blood flow in narrowed heart arteries. If you have stable or unstable chest pain or had a heart attack more than 72 hours ago and a CT shows a moderate blockage (70-90% narrowed), you might be eligible.
This study is following people with chronic coronary syndrome to see how a special CT-based blood flow test (CT-FFR) helps predict their heart health. If you have already had this test, you may be eligible to join and help doctors learn more about managing your condition.
This study compares new imaging methods to see how well they work and whether they can lower costs for people with suspected coronary artery disease. It may help by using different scan approaches while keeping patient safety in mind.
This trial compares two ways of deciding what to do next after a CT heart scan in people with stable chest pain. It looks at how well each approach helps doctors choose the safest next step (such as further testing or treatment).
This study uses a special heart CT scan (coronary CT angiography) to look at plaque and how blood flows in people with coronary artery disease. It may help match your scan results with heart measurements and guide future care decisions.
