Data are present as mean ± SD. Compared with control group,

^aP < 0.05 and

^bP < 0.01. PiCCO: Pulse index continuous cardiac output; APACHE II: Acute physiology and chronic health evaluation II; SOFA: Sequential organ failure assessment; Hs-TnI: High-sensitivity cardiac troponin I; NT-proBNP: N-terminal pro-brain natriuretic peptide; PaO2/FiO2: Oxygenation index; Lac: Lactate.
