Summary

Atrial fibrillation (AF) is the most frequently encountered cardiac arrhythmia. Emerging data suggests that common genetic variants are associated with the development of AF. The main feature of the structural remodelling in AF is atrial fibrosis and is considered the substrate for AF perpetuation. Genome-wide association studies suggest that AF-susceptibility variants may modulate atrial fibrosis. However, the association between atrial fibrosis and genetic polymorphisms in humans has not yet been specifically investigated. In this study, we plan to investigate the relationship between genetic polymorphisms, atrial fibrosis and other components of thrombogenic substrate in patients with non-valvular AF. Primary objectives of this study are to assess associations between (i) polymorphic genetic variants and atrial fibrosis (detected by magnetic resonance imaging), (ii) polymorphic genetic variants and components of thrombogenic substrate (inflammation, endothelial function, prothrombotic state, atrial functions).
