LA strain parameters
LA strain parameters were shown in Figure 2 and Table 3. Reduced LA strain was observed in both AL-CA group and HHD group. LASr and LASct were significantly lower (21.03 vs 26.17, P =0.01, and 12.11 vs 15.51, P=0.01, respectively) in AL-CA group than those in HHD group, while LAScd was not significantly different between the two groups (P=0.17). SD-TPS, SR-LAs, SR-LAe, and SR-LAa were similar between AL-CA group and HHD group. The cutoff values of LASr and LASct for discriminating between AL-CA and HHD were 19.53% and 11.34% according to ROC analysis, respectively. Correspondingly, the areas under the curve (AUCs) were 0.67, 95% CI [0.52–0.83] and 0.67, 95% CI [0.51–0.82], respectively (Figure 3).
