Fig. 2. Correlation between LV mass and LV longitudinal systolic strain. LVGLS and LVGLSR show significant correlations with LV mass (A and B). However, LVGLS and LVGLSR were not significantly correlated with LV mass index (C and D) (open circle: female, filled quadrangle: male). LV: left ventricular, LVGLS: LV global longitudinal strain, LVGLSR: LV global longitudinal systolic strain rate.
