Figure 2. Hemodynamic measures in upright (45°) and supine position at baseline rest, at 50% and 100% of individual work rate.

Figure 2

Means and SD of main hemodynamic measures assessed by right heart catheterization in upright (main cohort, n=217, black diamonds) and supine position (historical cohort, n=270, white squares) at baseline, and at 50% and 100% of individual end‐exercise work rate. *P<0.05 between groups in the adjusted regression analyses. A, Mean pulmonary artery pressure. B, Pulmonary artery wedge pressure. C, Cardiac index. D, Pulmonary vascular resistance. mPAP, mean pulmonary artery pressure; PAWP, pulmonary artery wedge pressure; PH, pulmonary hypertension; PVR, pulmonary vascular resistance; and WU, Wood units.
