  1. Variables with the Gaussian distribution are expressed as the mean ± standard deviation; those with different distribution are in italics as the median (lower quartile – upper quartile)
  2. Variables marked in bold and denoted with * have their ANOVA p-value < 0.05
  3. P-values of the post hoc tests < 0.05 are marked in bold
  4. LGE– negative late gadolinium enhancement, LGE+ positive late gadolinium enhancement, LV left ventricle, EF ejection fraction, LVMi left ventricular mass index (g/m2), EDVi end-diastolic volume index, ESVi end-systolic volume indexm, SVi stroke volume index
