Figure 2.

(A) Pulmonary capillary wedge pressure (PCWP) is positively correlated with left atrial pressure. Hemodynamic data are from the baseline catheterization performed at pulmonary hypertension diagnosis. (B) PCWP is positively correlated with left ventricular end-diastolic pressure (LVEDp) when LVEDp is more than 5 mm Hg. Hemodynamic data are from the baseline catheterization performed at pulmonary hypertension diagnosis. LAP = left atrial pressure; WSPH = World Symposium on Pulmonary Hypertension.
