Plasma miRNA levels in the validation population. The box plots show the expression levels of miR-26a-1 (a), miR-27a (b), miR-30d (c), miR-146a (d), miR-199a-1 (e) and miR-423 (f) measured by quantitative real-time polymerase chain reaction (qPCR) in AMI patients (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
