Is there a role for microRNAs as novel predictors of prognosis in myocardial infarction?

MicroRNAs (miRNAs) are endogenous, non-coding, single stranded RNA’s of 19–25 nucleotides in length that regulate gene expression at the post-transcription processing steps (1). Although the exact biological functions of miRNAs are still not fully understood they have been implicated in cellular development, differentiation, metabolism and death (2,3).
