Micro ribonucleic acids (miRNAs) are small non-coding RNA molecules that control gene expression by translational inhibition. They have been identified to play a role in a multitude of physiological and pathophysiological cellular processes amongst others in the heart. Due to their ability to be released into the blood as well as their stability in body fluids, they appear suitable as biomarkers. This review discusses the role of selected miRNA that currently emerge as biomarkers for coronary artery disease, their potential to discriminate between different diseases, as well as how they might be used as predictive tools for cardiac events or disease outcome. Furthermore, we propose procedural steps of miRNA analysis, to allow better comparison between studies in the future.
