Correlations between right ventricular systolic and diastolic function in incident and prevalent patients with PAH. Systolic function (Ees) correlates with RV diastolic stiffness coefficient (β) in incident (a, c) and prevalent (e) PAH patients. Correlation between Ees and Eed is more variable with no significant correlation in treatment-naïve PAH patients (b) and significant correlations after three months of therapy (d) and in a prevalent cohort of PAH patients (f).
