BACKGROUND:MicroRNAs(MiRNA) are a novel class of non-coding RNAs involved in the regulation of gene expression post-transcriptionally by cleavage or translational repression of their specific target miRNAs.Numerous studies have demonstrated that circulating miRNAs are stable and abundant in blood and aberrantly expressed under pathological conditions,including cardiovascular diseases.The implications of circulating miRNAs in acute myocardial infarction have recently been recognized.This review will highlight the potential role of miRNA as a novel class of biomarkers in acute myocardial infarction.METHODS:This systemic review is based on our own work and other related reports.RESULTS:During diseases circulating miRNAs are derived from not only circulating blood cells but also other tissues affected by ongoing diseases.These disease-related miRNAs in the blood can serve as potential biomarkers.CONCLUSION:The circulating miRNAs can be used as novel biomarkers potentially offering more sensitive and specific tests than those currently available for diagnosis of acute myocardial infarction.

Pediatric restrictive cardiomyopathy is rare and most commonly idiopathic in origin. Here, we applied a candi- date gene approach and identified a missense mutation in the cardiac troponin I gene in a 12-year-old Chinese girl with restrictive cardiomyopathy. This study indicates that mutation in sarcomere protein genes may play an im- portant role in idiopathic pediatric restrictive cardiomyopathy.
