Serum was collected, fluorescent quantitative PCR kit was used to detect miR-148b expression, and enzyme-linked immunosorbent assay kit was used to detect the contents of myocardial injury markers and myocardial fibrosis markers.Results:Serum miR-148b expression as well as CK-MB, cTnT, H-FABP, PICP, PIIINP, CTX-I, TGF-β1 and GDF-15 levels in AMI group was significantly higher than those in control group;serum CK-MB, cTnT, H-FABP, PICP, PIIINP, CTX-I, TGF-β1 and GDF-15 levels in AMI patients with high miR-148b expression were significantly higher than those in AMI patients with low miR-148b expression.Conclusion: Highly expressed miR-148b in serum of patients with myocardial infarction can promote myocardial injury and myocardial fibrosis.展开更多
