description

Fractional flow reserve (FFR) and coronary flow reserve (CFR) provide different and complementary information on vascular physiology. The two tests provide information, respectively, on the epicardial and total vascular resistances. Typically, a FFR <0.75 is also associated with an impaired CFR (<2); exceptions, however, exist.
