A method of determining one or more diagnostic metrics to assess a blood vessel using intravascular data includes: sampling a sensor of an intravascular data collection probe disposed in the blood vessel during a pullback of the intravascular data collection probe through the blood vessel to obtain sampled distal pressure (Pd) values; receiving, at an intravascular data processing system, the sampled distal pressure (Pd) values and proximal pressure (Pa) values; determining sets of Pd/Pa ratios, each set including Pd/Pa ratios that are determined through an entirety of one heart cycle; determining minimum Pd/Pa ratios, each of which is a minimum within one of the sets of Pd/Pa ratios over the entirety of the corresponding heart cycle; and controlling a display system to generate a plot of a moving average of the minimum Pd/Pa ratios over time during the pullback.
