Data are mean values ± standard deviations. Ax-Tx time, duration between lung transplant assessment and lung transplantation; BMI, body mass index, calculated as the weight in kilograms divided by height in meters squared; FEV1, forced expiratory volume in 1 second; FVC, forced vital capacity; GBPS, gated blood pool scan; LVEF, left ventricular ejection fraction; PaCO2, partial pressure of arterial carbon dioxide; PaO2, partial pressure of arterial oxygen; RV, residual volume; RVEF, right ventricular ejection fraction; RVSP, right ventricular systolic pressure; TLC, total lung capacity; TLCO, transfer factor of the lung for carbon monoxide.
