GIII values significantly different from those of other groups
CG: control group; GI: indeterminate form; GII: electrocardiographic abnormalities and LV ejection fraction ≥ 0.55; GIII: electrocardiographic abnormalities and LV ejection fraction < 0.55; E wave: E wave in mitral flow; A wave: A wave in mitral flow; E/A: E wave/A wave ratio; DTE: E wave deceleration time; LVEF: left ventricular ejection fraction.
