Data are presented as mean±sd, unless otherwise stated. FEV1: forced expiratory volume in 1 s; FVC: forced vital capacity; DLCO: diffusing capacity of the lung for carbon monoxide; TLC: total lung capacity; RV: residual volume; PaO2: arterial oxygen tension; PA–aO2: aveolar–arterial oxygen tension gradient; LV: left ventricular; DD: end-diastolic dimension; SD: end-systolic dimension; RV: right ventricular; 6MWD: 6-min walking distance.
