Figure 1.
Serum concentration of troponin I. The serum concentration of troponin I at baseline before (preop) and over 72 h after coronary artery bypass graft (CABG) surgery in patients undergoing remote ischemic preconditioning (RIPC; n = 23, black symbols/bars) or placebo (n = 23, white symbols/bars). Decreased troponin I concentrations confirmed protection by RIPC. Insert: area under the curve (AUC) for serum troponin I concentrations over 72 h. +p < 0.05 versus RIPC using 2-way ANOVA for repeated measures or unpaired Student’s t-test (AUC).
