Kaplan–Meier Curves for (A) radial, (B) circumferential and (C) longitudinal strain with thresholds obtained from receiver operator curves. For radial strain, which is a positive, patients with strain greater than the threshold had better survival (p<.001). Circumferential and longitudinal strain are negative and for those strains, patients with strains lower (more negative) than the threshold had better survival. Circumferential strain p=.001. Longitudinal strain p<.001.
