Figure 5. Kaplan‐Meier survival curves for artificial intelligence (AI)‐measured global longitudinal shortening (GL‐Shortening) and mitral annular plane systolic excursion (MAPSE) for the outcome data set.

Figure 5

Based on the log‐rank statistic, MAPSE (A, C, and E) associated more strongly with outcomes of the composite of hospitalization for heart failure (HHF) or death (top row, n=335), death only (middle row, n=250), and HHF in survivors (bottom row, n=147) than the GL‐Shortening (B, D, and F) among participants (n=1572). To illustrate dose‐response relationships in both MAPSE and GL‐Shortening, Kaplan‐Meier curves relative to the median, standard deviation increments separated the strata, with the top 2 strata above the median and the lower 3 strata below the median (given the skewed distributions visible on histograms). CMR indicates cardiac magnetic resonance.
