Analysis of peak right ventricular free wall (RVFW) contractility γRVFW,max for control and pulmonary arterial hypertension (PAH) groups. A: graphical depiction of γRVFW,max for both controls (diamonds) and patients (black dots) as a function of the ratio of right ventricular end-diastolic volume to left ventricular end-diastolic volume (RVEDV/LVEDV). Dashed line shows a linear fit to the patients with PAH group (γRVFW,max = –0.13 (RVEDV/LVEDV) +0.44, R2 = 0.77). B: average γRVFW,max for controls, patients with RVEDV/LVEDV < 1.5, and patients with RVEDV/LVEDV ≥ 1.5. C: linear fit of γRVFW,max with RVEDV index (RVEDVi; γRVFW,max = –0.001 (RVEDVi) +0.32, R2 = 0.40). D: linear fit of γRVFW,max with right ventricular ejection fraction (RVEF; γRVFW,max = 0.39 (RVEF) +0.09, R2 = 0.50). *P < 0.05.
