Fig. 2. Cardiac troponin I concentrations in the propofol and sevoflurane groups before surgery (control), at arrival in the intensive care unit (T0), and after 3 (T3), 12 (T12), 24 (T24), and 36 h (T36). The upper panels show the median values with 95% confidence intervals. The lower panels show the evolution of the individual values. Concentrations were significantly higher with propofol. In the propofol group, all patients had troponin concentrations above the cutoff value off 2 ng/ml (gray line).
