ROC curves for distinguishing infarcted and remote myocardium based on strain parameters. In SPCS the optimal cut-off is − 7.2% (sensitivity of 89.4% and specificity of 85.7%) and in SPRS the optimal cut-off is 16.6% (sensitivity of 83.3% sensitivity and specificity of 76.5%). ROC Receiver operating characteristic, SPCS segmental peak circumferential strain, SPRS segmental peak radial strain.
