  1. Data were presented as mean ± SD. *Dynamic result based on 3 slices (clinical routine 2-, 3-, and 4-chamber views); P values obtained using Mann-Whitney U test. Sm: peak systolic velocity; Em: peak early diastolic velocity; Am: peak late diastolic velocity; MAPSE: mitral annular plane systolic excursion.
