  1. 6-MWT = six minute walk test; FEV1 = forced expiratory volume within first second; MEF75, 50, 25 = maximal expiratory flow at 75%, 50%, 25% of remaining VC; NT-proBNP = N-terminal-pro-B-type natriuretic peptide serum level; RV = residual volume, Rtot = airway resistance; sPAP = systolic pulmonary artery pressure as determined from tricuspid regurgitation velocitiy during echocardiography, TLC = total lung capacity, VC = vital capacity. Data are presented as mean ± SD.
