Micro ribonucleic acids (miRNAs) are short non-coding RNA molecules responsible for regulation of gene expression. They are involved in many pathophysiological processes of a wide spectrum of diseases. Recent studies showed their involvement in atrial fibrillation. They seem to become potential screening biomarkers for atrial fibrillation and even treatment targets for this arrhythmia. The aim of this review article was to summarize the latest knowledge about miRNA and their molecular relation to the pathophysiology, diagnosis and treatment of atrial fibrillation.

The International Research Interdisciplinary School (IRIS), originally named the International Scientific Summer School (ISSS), provides an interdisciplinary international environment for training skills required for preparing research study protocols and scientific manuscripts and for international collaboration especially in the field of cardiovascular biomedicine. It is a common initiative of several scientific journals aiming to provide support for young researchers in their research career, in preparing their research projects and succeeding in publications.
