Identification of Genetic, Biochemical and Hormonal Factors Contributing to Atrial Fibrillation

Blood samples and data will be collected from subjects with atrial fibrillation and normal
controls. The primary aim of future research using these samples is to identify mechanisms
and pathogenesis of atrial fibrillation. Through this information, we hope to identify
targets for new therapies and improve knowledge and understanding of atrial fibrillation.
Identification of disease genes could improve strategies that prevent progression of atrial
fibrillation to more persistent disease.
