Abstract
Objective. To assess the prognostic value of circulating microRNA-29a expression levels in relation to cardiac arrhythmias detected by 24-hour (Holter) ECG monitoring in patients with hypertrophic cardiomyopathy (HCM).
Materials and methods. The study included 41 patients with a verified diagnosis of HCM (21 men, 20 women), with a mean age of 57.2±14.2 years. All patients underwent 24-hour ECG monitoring. The expression level of microRNA-29a in plasma was measured using RT-qPCR. The Mann–Whitney U test was used for statistical analysis (p < 0.05).
Results. In patients with arrhythmias, the level of microRNA-29a was significantly lower compared to those without arrhythmias (0.206 vs. 0.433; p = 0.0015). No statistically significant associations were found between miR-29a expression and conduction disturbances.
Conclusion. Reduced expression of microRNA-29a may be associated with an increased risk of arrhythmias in patients with HCM. This epigenetic marker could serve as a valuable addition to existing risk stratification tools and warrants further investigation in larger patient cohorts.
