  1. Data are expressed as the mean ± SD
  2. LVEDD LV end-diastolic dimension, E/A ratio the ratio of E-wave and A-wave, IVRT isovolumic relaxation time, EDT E-wave decline time, EF ejection fraction, FS fractional shortening, HR heart rate, CO cardiac output
  3. ##P < 0.05 as DCM group vs. CON group, ** P < 0.01 as AIT group vs. DCM group, * P < 0.05 as AIT group vs. DCM group (ANOVA)
