Existing markers of myocardial infarction have limited diagnostic value for infarction, so it is necessary to identify new markers of infarction. To study the predictive value of serum miRNA-203 for acute ST-elevation myocardial infarction. Seventy patients with STEMI who were diagnosed in Hefei Second People's Hospital from December 2020 to December 2021 were selected, and 35 patients with transient chest pain who were hospitalized for other diseases in the Cardiology Department of our hospital during the same period were selected as the control group. The sera of the two groups of patients were collected, and a miRNA-203 semiquantitative experiment was performed. The miRNA-203 level in the STEMI group was higher than that in the control group. The AUC area of miRNA-203 in predicting STEMI was 0.912. Logistic regression analysis showed that miRNA-203 and white blood cell counts were independent risk factors for STEMI (P<0.05), and their ORs (95% CI) were 3.913 (1.574-9.728) and 2.13 (1.247-3.641), respectively. The present study reveals that miRNA-203 could be a possible candidate for a novel biomarker in the early prediction of STEMI.
