Circulating type IV collagen 7S concentrations are associated with left atrial remodeling indices in patients with atrial fibrillation.

Objective: Non-alcoholic fatty liver disease is a risk factor for atrial fibrillation. We assessed whether liver fibrosis markers are associated with atrial remodeling indicators in patients with atrial fibrillation in whom fatty liver disease has not been identified.

Methods: In this prospective, observational study, 174 patients with atrial fibrillation without chronic liver disease who underwent catheter ablation were enrolled.
