  1. General demographic data for all groups. To test for differences between the different groups (last column) ANOVA with posthoc Dunnets (controls as reference) was used for normally distributed data and Kruskal Wallis analysis of variance with Mann Whitney U tests for non-normally distributed data. #p < 0.05, *p < 0.01, **p < 0.001. Abbreviations: BSA body surface area, RVSP right ventricular systolic pressure, VO 2 /kg peak oxygen uptake per kg, %PredVO 2 /kgg % of predicted peak oxygen uptake, RV right ventricular, EDV end-diastolic volume ESV end-systolic volume, EF ejection fraction
