Study Subject Data

Note.—With exception of P values, data are median values, with 25th–75th percentile ranges in parentheses.

^*BSA = body surface area, EDV = end-diastolic volume, ESV = end-systolic volume, PVRI = pulmonary vascular resistance index, RPP = rate-pressure product, sPAP = systolic pulmonary arterial pressure, VMI = ventricular mass index.

^†P values for comparison between non-PAH, PAH, and control groups with the Kruskal-Wallis test. Only in the cases of significance, the Mann-Whitney U test was then used for intergroup comparisons.

^‡NS = not significant after Bonferroni correction, accounting for the 29 variables tested.

^§Only the Mann-Whitney U test was used for these direct comparisons.

^‖P < .05 (Mann-Whitney U test) for intergroup comparisons.

^#P < .01 (Mann-Whitney U test) for intergroup comparisons.

^**MPRI of LV wall, with septum excluded.
