Data are expressed as median (25-75th percentiles) or proportion of patients in %
*Data are calculated as median (25-75th percentiles) only for cases with cardiopulmonary bypass (n = 385)
BMI: body mass index; COPD: chronic obstructive pulmonary disease; GFR: glomerular filtration rate; LVEF: left ventricular ejection fraction; surgical delay: delay between diagnostic coronarography and surgery; OPCABG: off-pump coronary bypass graft; CABG: coronary artery bypass graft with cardiopulmonary bypass; Valve surgery: aortic valve replacement or mitral valve repair/replacement surgery; Valve and CABG: aortic valve replacement or mitral valve repair/replacement surgery combined with coronary artery bypass graft; CPB: cardiopulmonary bypass; MAP: mean arterial pressure.*: n = 385; ICU: intensive care unit
