Figure 4 Clinical Response to CRT Based on CMR Findings

These plots show data for individual improvement in function class for patients in the CRT-HF cohort based on baseline characteristics such as QRSd (A), CURE (B), and percent left ventricular scar volume by delayed enhancement-cardiac magnetic resonance (DE-CMR) (C). Those with function class improvement are shown in the left column of each panel, and those without improvement are shown in the right column of each panel. The QRSd (A) has no association with improvement in function class. MR-MT (B) has better accuracy (90%) than DE-CMR (78%) and (C) MR-MT and DE-CMR combined have superior accuracy (95%). This highlights the superior accuracy of CURE for predicting function class improvement. Abbreviations as in Figures 1 and 3.
