Autoimmunity in the Pathogenesis of AF

February 17, 2022 updated by: Rowlens M. Melduni, Mayo Clinic

The Role of Autoimmune Mechanisms in the Pathogenesis of Atrial Fibrillation

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

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.
