Abstract: The resting full-cycle ratio (RFR) is a new physiologic index to assess myocardial ischemia. RFR and fractional flow reserve (FFR), the conventionally used index, have not been directly compared in evaluating the entire cardiac cycle.… read more here.

DOI: 10.1016/s0735-1097(20)32078-7
Abstract: Diagnostic accuracy of NHPRs including Pd/Pa, iFR and RFR is ~80% when compared to FFR. The differential performance of NHPR among the different coronary arteries has been observed but not systematically studied. We evaluated the… read more here.

DOI: 10.12998/wjcc.v11.i10.2123
Abstract: Hemodynamical evaluation of a coronary artery lesion is an important diagnostic step to assess its functional impact. Fractional flow reserve (FFR) received a class IA recommendation from the European Society of Cardiology for the assessment… read more here.
