miRNAs(microRNAs,miRs) have very important role in regulating cardiac pathophysiologic progress. The expressing level and phenotype of miRNAs are different in myocardial injury, it can be regarded as sensitive and specific biomarker for diagnosis in cardiovascular diseases. Because of the regulating mechanism of miRNAs, it can be used as a better and more accurate therapeutics to treat heart diseases.%miRNAs(microRNAs,miRs)在调节心脏病理生理的发展过程中起着极其重要的作用.miRNAs可作为诊断心血管病敏感且特异的标志物,在不同的心肌损伤中其表达水平和表型各不相同.充分利用miRNAs的调节机制可以更精确且有效的治疗心血管疾病.
