Figure 3. Effect of reperfusion duration on myocardial enzyme release. (A) Myocardial enzyme concentrations of LDH. (B) Myocardial enzyme concentrations of CK. (C) Myocardial enzyme concentrations of CK-MB (n = 3 : 3 : 3 : 3). MI=Myocardial infarction, Rep=reperfusion. Data are shown as mean ± SD. One-way ANOVA followed by Tukey post hoc test was used for statistical comparisons between multiple groups. *P < 0.05; **P < 0.01; ***P < 0.001.
