FAC left atrial fractional area change, HCM hypertrophic cardiomyopathy, LAD left atrial diameter, LA-EF left atrial ejection fraction, LA-FS left atrial fractional shortening, PALS peak atrial longitudinal strain
Data are expressed as mean ± standard deviation
*indicate statistical significance at P < 0.05 of 3 subgroups
The significance difference was assessed by Kruskal Wallis test
^a and ^b indicate significant difference
