ABSTRACT
Introduction:
The aim of this study was to investigate the relationship between ferroptosis and myocardial fibrosis in atrial fibrillation (AF).

Material and methods:
The patient’s left atrial appendage tissue was obtained in cardiac surgery. Sirius red staining, Prussian blue and Western blot were used to detect staining to assess histological fibrosis and ferroptosis changes.

Results:
There is a certain correlation between the degree of tissue fibrosis and ferroptosis in AF (r = 0.7763, p = 0.0004). The key proteins related to the regulation of ferroptosis were significantly abnormal in the AF group.

Conclusions:
Ferroptosis is involved in myocardial fibrosis of AF and is a potential target for the diagnosis, prevention and treatment of AF.
