  1. Volumes are given in ml/m2 body surface area (BSA), mass in g/m2 BSA, strain and HDF values in %. Independent continuous parameters are presented as median with interquartile range and were compared by using the Wilcoxon signed-rank test. Bold p-values indicate statistical significance.
  2. LV left ventricular, EDV enddiastolic volume, ESV endsystolic volume, SV stroke volume, EF ejection fraction, GLS global longitudinal strain, RMS root mean square.
