Receiver-operator characteristic analysis showed that hMR had a numerically superior diagnostic accuracy over IMR to predict MPRI, although the difference did not reach statistical significance (AUC, 0.85 vs 0.72, p = 0.19) ( Figure 6 ).

23 Patel et al demonstrated that hMR had a superiority trend over IMR in predicting parameters of infarct size and impaired LV ejection fraction, but this failed to reach statistical significance. 23 However, they did not include measurements of MVD in this comparison.
