  1. Data expressed as mean ± standard deviation (SD); LV left ventricular, NC normal controls, LVEF left ventricular ejection fraction, HT-NEF hypertension with normal LVEF, HT-REF hypertension with reduced LVEF, SL longitudinal strain, SC circumferential strain, SR radial strain; −mv, −pm, −ap indicates basal level, papillary and apical level;
  2. p < 0.05 vs NC; p < 0.05 vs group HT-NEF
