BACKGROUND: Acute myocardial infarction (AMI) is myocardial necrosis caused by acute and persistent ischemia and hypoxia of coronary arteries. AMI is one of the most common diseases in European countries and over 1.5 million AMI patients die of it in the United States annually. A collection of studies proposed that certain micro-RNAs play crucial roles in the onset and development of AMI. METHODS: Ninety-four AMI patients and 83 non-AMI healthy controls were recruited from Zhongda Hospital, Southeast University between July 2015 and September 2017. Serum samples were collected at admission and the expression of miR-142 was detected using real-time quantitative polymerase chain reaction (RT-qPCR) assays. RESULTS: miR-142 expression was markedly elevated in serum samples of AMI patients compared with the 83 non-AMI healthy controls. miR-142 expression was positively correlated with creatine kinase-KB (CK-MB; r = 0.6731, p = 0.0021) and troponin (r = 0.7138, p = 0.0013). The area under the curve (AUC) of miR-142, CK-MB, and troponin for the diagnosis of AMI were 0.9185, 0.8172, and 0.8717, respectively. Overall survival analysis implied that high miR-142 expression may predict poor survival (log-rank test, p = 0.0146). CONCLUSIONS: miR-142 may be a diagnostic and prognostic indicator for AMI, and therefore, it may contribute to AMI clinicopathologic prediction.
