Youden index	0.3659	0.4185	0.4094	0.3876	0.5322
AUC (95%CI)	0.735 (0.647-0.811)	0.753 (0.666-0.827)	0.750 (0.663-0.825)	0.735 (0.646-0.811)	0.801 (0.719-0.869)
Associated criterion	-17.0	-19.8	-23.5	32	0.44
P value	0.064	0.127	0.103	0.050

P values mean combined evaluation compare with global longitudinal strain and peak strain dispersion. GLSEpi: Global longitudinal strain of the epimyocardial; GLSMid: Global longitudinal strain of the middle myocardial; GLSEndo: Global longitudinal strain of the endomyocardial; PSD: Peak strain dispersion; ROC: Receiver operating characteristic; AUC: Area under the curve.
