Brief Summary:
This research study is being done to find out whether autoimmune mechanisms are associated with the development of atrial fibrillation.

Condition or disease Intervention/treatment
Atrial Fibrillation Other: Peripheral Blood Sample

Detailed Description:
The study sets out to identify an explanation for the pathogenesis of AF, potentially forming the basis for designing novel targeted therapies to prevent or reverse this prevalent human disease. The overall objectives are to determine whether autoimmune diseases are associated with AF development and to identify specific diagnostic and prognostic biomarkers that will improve the ability to accurately predict risk of AF development. The study will prospectively enroll patients with and without AF and determine their serum cytokine levels and assess the functional responses of T cells on the basis of cytokine production after in vitro T-cell specific stimulation, using Luminex bead-based multiplex technology.
