FVC: forced vital capacity as percentage of predicted values; FEV1: forced expired volume in the 1 second as percentage of predicted values; PaO2: arterial oxygen tension; PaCO2: arterial carbon dioxide tension; PAP: mean pulmonary artery pressure; : cardiac output measured by radiologic method (radiol) and Fick method (Fick); PVR: pulmonary vascular resistance; 6 MWD: six minutes walking distance; WHO: dyspnoea rating according to WHO stages; and GOLD st. II-III and IV: % of patients belonging to GOLD stages II, III, and IV.; Values are expressed as mean ± standard deviation; : number of observations. |
