Background MicroRNAs (miRNAs) are involved in the pathogenesis of atrial fibrillation (AF),
acting on development and progression. Our pilot study investigated the expression of six …

Background MicroRNAs (miRNA) s regulate expression of genes involved in various
processes including cardiac automaticity, conduction, excitability, and fibrosis and therefore …

Atrial fibrillation is the most frequent type of cardiac arrhythmia in humans, with an estimate
incidence of 1–2% in the general population, rising up to 8–10% in the elderly …

Highlights•miR423-5p discriminated patients with HF from those with other causes of
dyspnea.•miRNA-related pathophysiological mechanisms of AF were shown for miR-21 and …

Atrial fibrillation is the most common sustained arrhythmia associated with substantial
cardiovascular morbidity and mortality, with stroke being the most critical complication. The …

The potential of extracellular circulating microRNAs (miRNAs) as non-invasive biomarkers of
atrial fibrillation (AF) has been confirmed by a number of recent studies. However, the …

Background Among the potential factors which may contribute to the development and
perpetuation of atrial fibrillation, dysregulation of miRNAs has been suggested. Thus in this …

MicroRNAs (miRNAs) are a class of small non-coding RNA molecules that play a role in post-
transcriptional gene regulation. It is generally accepted that their main mechanism of action …

Background Structural changes of the left and right atria associated with atrial fibrillation (AF)
in mitral stenosis (MS) patients are well known, and alterations in microRNA (miRNA) …

Background Studies have reported that the integrated analysis of microRNA (miRNA)-
messenger RNA (mRNA) expression is valuable in exploring gene regulation systemically …
