Addition of Computed Tomography–Derived Fractional Flow Reserve in the Diagnostic Pathway of Patients With Stable Coronary Artery Disease
- Randomised controlled trial
- investigator-initiated
- multicentre
Authors' conclusion
Adding FFRct to the diagnostic pathway of patients with a 50% to 90% stenosis on CCTA reduced the rate of ICA without obstructive CAD at 90 days and 1 year, without differences in revascularizations, quality of life, and costs compared with usual care.

- Comparison
- FFRct-guided vs usual care
- FFRctn = 263
- Usual caren = 265reference
- Primary endpoint
- ICA without obstructive CAD
- Follow-up
- 90 days

Events by treatment group
Secondary outcomes
ICA use (post hoc exploratory) · 90 days · post hoc exploratory endpoint
P = 0.004
| Outcome | P value |
|---|---|
| Revascularization · 1 year | P = 0.948 |
Invasive coronary angiography (ICA) without obstructive CAD and ICA use · 1 year
- Both differences persisted at 1 year
Quality of life, costs, MACE
- Did not differ between groups; clinical event rates low
