Delineation of epicardial stenosis in patients with microvascular disease using pressure drop coefficient: A pilot outcome study

Figure 3 Comparison of %MACE between fractional flow reserve < 0. 75 and pressure drop coefficient > 27.9 groups for the coronary flow reserve < 2.0 subgroup and diabetic subgroup. These patient subgroups are obtained from the complete patient group analyzed in Effat et al[22]. The P-values are provided for the χ² test, and the P-values for the Fischer’s exact test are provided in parentheses. CDP: Pressure drop coefficient; FFR: Fractional flow reserve.
