Correlation Of CoAGulation Biomarkers and Atrial Fibrillation Burden in Patients Post Catheter Ablation: the COAG-AF Pilot Study
Tulane University
Summary
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.
Description
COAG-AF is a 3-month prospective observational study in patients diagnosed with atrial fibrillation and undergoing a first-time ablation procedure. It will be a pilot study consisting of approximately twenty patients. Patients will undergo a baseline blood draw prior to ablation. A cardiac MRI (LGE-MRI) scan will also be performed prior to ablation and is part of standard of care in patients undergoing ablation. During catheter ablation, blood will be taken simultaneously from a peripheral blood vessel and from the left atrium (LA) at two different timepoints. Patients will have additional…
