Circulating miR-499 as a potential biomarker for acute myocardial infarction.

Acute myocardial infarction (AMI), a common heart disease that may lead to chronic heart failure, is the leading cause of morbidity and mortality worldwide. MicroRNAs (miRNAs) are small non-coding RNAs that mediate the expression of target genes. Recently, a number of miRNAs are emerging as potential biomarkers of AMI.
