  1. Values are Mean ± SD. WHW/BW whole heart weight normalized by body weight; LVW/BW left ventricular weight normalized by body weight; LVW/WHW left ventricular weight normalized by whole heart weight; WHW/Tibia whole heart weight normalized by tibia length; LVW/Tibia left ventricular weight normalized by tibia length; IVSd inter-ventricular septum at diastole; LVPWd left ventricular posterior wall thickness at diastole; LVIDd internal dimension at diastole of left ventricle; LVIDs internal dimension at systole of left ventricle; FS: fractional shortening (LVIDd-LVIDs/LVIDd x100)
  2. * P < 0.05, significant differences from the Control group. #P < 0.05, ##P < 0.01, significant differences from the Hypoxia group
