Continuous data are expressed as mean ± SD. Categorical variables are expressed as n (%). PiCCO: Pulse index continuous cardiac output; BMI: Body mass index; APACHE II: Acute physiology and chronic health evaluation II; SOFA: Sequential organ failure assessment; Hs-TnI: High-sensitive Troponin I; NT-proBNP: N-terminal pro-brain natriuretic peptide; PaO2/FiO2: Oxygenation index; Lac: Lactate.
