Abstract: Fractional flow reserve (FFR) and nonhyperemic pressure ratios (NHPRs) have been widely used to assess the functional severity of coronary stenosis. However, their measurement requires using a pressure wire, making their use in all patients… read more here.

Abstract: Invasive coronary physiology to measure fractional flow reserve (FFR) or nonhyperemic pressure ratios (NHPRs) requires vessel instrumentation using a pressure wire. Although modest, the pressure wire and its insertion carry some cost and risk. Deriving… read more here.
