Brief Summary
Quantitative Flow Ratio (QFR) is a novel method for evaluating the functional significance of coronary stenosis. QFR is estimated based on two angiographic projections. Studies have shown a good correlation with the present wire-based standard approach Fractional Flow Reserve (FFR) for assessment of intermediate coronary stenosis. The purpose of the FAVOR III Europe Japan study is to investigate if a QFR-based diagnostic strategy will results in non-inferior clinical outcome after 12 months compared to a standard pressure-wire guided strategy in evaluation of patients with chest pain (stable angina pectoris) and intermediate coronary stenosis.

Study Arms (2)
QFR-based diagnostic strategy
EXPERIMENTALIntermediate stenosis with indication for evaluation are diagnosed by Quantitative flow ratio (QFR). Revascularization is indicated if QFR≤0.80. Treatment is performed according to standard clinical practice.
FFR-based diagnostic strategy
ACTIVE COMPARATORIntermediate stenosis with indication for evaluation are diagnosed by fractional flow reserve (FFR). Revascularization is indicated if FFR≤0.80. Treatment is performed according to standard clinical practice.
Interventions
Novel computer based calculation of lesion severity. Pressure wire-free and adenosine-free
Standard FFR based diagnostic method. Pressure drop across the stenosis is measured with a pressure wire during medical induced hyperaemic conditions
Eligibility Criteria
You may qualify if:
- Age of 18 years and above

- Able to provide written informed consent
- Diameter stenosis of 40-90% diameter stenosis
- Vessel diameter of at least 2.5 mm and supplying viable myocardium
- Patients with restenosis in a native coronary artery can be included
