Correlation Of CoAGulation Biomarkers and Atrial Fibrillation Burden in Patients Post Catheter Ablation: the COAG-AF Pilot Study
The aim of the Correlation Of CoAGulation-Atrial Fibrillation (COAG-AF) study is to prove that an increase in pro-thrombotic biomarkers in AF is associated with an increase in AF burden. Secondary objectives of the study are the following: * To investigate the impact of catheter ablation on serum pro-thrombotic biomarkers in patients with AF. * To correlate coagulation biomarkers with imaging features such as, the degree of fibrosis found on Late Gadolinium Enhancement Magnetic Resonance Imaging (LGE-MRI) scans, which is a part of standard of care. * To determine baseline values of coagulation and pro-thrombotic biomarkers in the AF population and compare those baseline values with the general population values. * To compare central and peripheral thrombotic biomarkers in patients with atrial fibrillation.
• Patients, male or female and older than 18 years of age.
• Patients diagnosed with persistent or paroxysmal AF.
• Patients that are undergoing catheter ablation at Tulane University Medical Center.
• Patients that had a cardiac MRI prescribed by their physician as part of their standard of care.
