Computed Tomography-derived Fractional Flow Reserve vs. Angiographic Quantitative Flow Ratio in Management of Patients With Coronary Artery Disease
1,402 participantsStarted 2026-03-01
Plain-language summary
This is a multi-center, randomized controlled trial to compare the clinical outcomes between CT-derived fractional flow reserve (CT-FFR) guided strategy and angiography-derived quantitative flow ratio (QFR) guided strategy among patients with coronary artery disease (CAD). Participants who have at least one coronary stenosis of 70%-90% (vessel diameter ≥2.5 mm) detected by coronary CT angiography will be enrolled and are randomly assigned in a 1:1 ratio to CT-FFR guided group or QFR guided group. In CT-FFR group, the decisions of invasive angiography and revascularization will be guided by CT-FFR. In QFR group, the decision of invasive angiography will be made as usual care, and revascularization will be guided by QFR. The primary endpoint is the 1-year incidence of major adverse cardiac events (MACEs), including death, myocardial infarction, and unplanned revascularization.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.

. Severe valvular heart disease, aortic disease, or large ventricular aneurysm requiring surgery.
. Atrial fibrillation or other severe cardiac arrhythmias.
. Refusal or inability to sign informed consent.
. Poor-quality CCTA images that prevent CT-FFR analysis.
. Severe coronary vessel tortuosity, overlapping segments, or other factors expected to cause poor-quality invasive angiography, hindering QFR measurement.
