ROC curves for distinguishing infarcted and remote myocardium based on segmental strain parameters. Below a SPCS value of − 5.9% (sensitivity of 86.2%, specificity of 83.5%, AUC 0.89 [95% CI 0.878–0.923, p < 0.05]) segments are considered infarcted. The cut-off value for SPRS was 20.2% (sensitivity of 77.5%, specificity of 77.9%, AUC 0.78 [95% CI 0.718–0.814, p < 0.05]) and − 6.6% for SPLS (sensitivity of 60.4%, specificity of 72.9%, AUC 0.66 [95% CI 950.598–0.715, p < 0.05]). Infarcted segments in LGE were considered gold standard.
