Data are expressed as (SD), numbers, or median (interquartile range). F: female; M: male; PBW: predicted body weight, calculated as follows: for women , for men ; ASA: American Society of Anesthesiologist; BMI: body mass index; CVD: coronary vessel disease; LEF: left ventricle ejection fraction; FVC: forced vital capacity; FEV1: forced expiratory volume in the first second; SaO2: oxyhaemoglobin saturation.
