Abstract Background: Fractional Flow Reserve (FFR) is recommended by society guidelines for assessment of the hemodynamic significance of intermediate coronary lesions when non-invasive evidence of myocardial ischemia is unavailable. However, little information is known about how FFR impacts revascularization decisions. Methods: We enrolled all patients referred for coronary angiogram for any indication at our institution from the period from May 2012 until January 2014. FFR was measured in all intermediate coronary lesions (30–70% stenosis). Based on the FFR results, the lesions were categorized into 3 different groups: FFR >0.80 (non-ischemic), FFR 0.75–0.80 (grey-zone), and FFR 0.80 (non-ischemic), FFR 0.75–0.80 (greyzone), and FFR
