3.4 Diagnostic efficiency of 3D strain parameters
The areas under the curve (AUC ) of LVtw, Tor, and MCI were all > 0.8 (P< 0.05), the sensitivity and specificity were all > 60%, and the Youden indices were all > 0.5. Among them, the AUC of the MCI was the highest (0.909), the sensitivity of MCI was the highest (90.00%), and the specificity of Tor was the highest (86.67%) (Table 5, Figure 5).
