Data are presented as mean ± SD, unless otherwise indicated. Dlco = diffusing capacity of the lung for carbon monoxide; LAP = left atrial pressure; mPAP = mean pulmonary artery pressure; PAd = diastolic pulmonary artery pressure; PAOP = pulmonary artery occlusion pressure; PVR = pulmonary vascular resistance; RAP = right atrial pressure.
