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.

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 study compares a CT-based method to measure blood flow in the heart with the standard invasive test, to see if it can help guide treatment for people with chest pain. It aims to reduce the need for invasive procedures.
This trial compares two non-invasive imaging tests to help doctors decide whether patients with narrowed heart arteries need stents or surgery. One test uses a CT scan, the other uses a standard angiogram, both measuring blood flow to guide treatment.
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 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.
