Figure 5

A. ROC-curve for longitudinal strain, circumferential strain and radial strain to discriminate between predominantly viable segments (0–50% necrosis) and transmural necrotic segments (>50% necrosis). The area under the curve is significantly larger for longitudinal strain when compared to circumferential strain (p < 0.05) and radial strain (p < 0.01). B. ROC curve analysis for strain parameters to separate transmural necrotic segments (>50% necrosis) from predominantly viable (0–50% necrosis). AUC = Area under the curve; CI = Confidence interval; CS = Circumferential strain; LS = Longitudinal strain; RS = Radial strain. *p < 0.05 versus circumferential strain. #p < 0.01 versus radial strain.
