Fig. 2

Plasma miRNA levels in the validation population before and after PCI. The box plots show the expression levels of miR-26a-1 (a), miR-146a (b) and miR-199a-1 (c)measured by qPCR in patients with AMI (including before and after PCI) (n = 31) and control subjects (n = 27). The relative miRNA expression levels were normalized to cel-miR-39 and calculated by –ΔΔCt. *p < 0.05, **p < 0.01, ***p < 0.001, compared with control subjects
