dPR is a diastolic pressure ratio. Measuring different parts of diastole yields results that are numerically identical.

Selecting the wave-free period is not necessary for calculating results numerically identical to iFR.

VERIFY 2: dPR is within the Intra-iFR Variation of ~0.01*,3

Pd/Pa calculates the entire cardiac cycle at rest.

“Pd/Pa seems to offer a universal resting physiological metric with equivalent agreement to iFR. Although not numerically identical, 1 index can be linearly transformed into the other, much like the conversion of units of temperature. Using the binary cutoff of iFR ≤0.89 as a reference standard, Pd/Pa...
