Atrial Fibrillation Clinical Trial
Official title:
Pre Procedural High Serum Visfatin and Tumor Necrosis Factors "Alpha" Might Predict Recurrent Atrial Fibrillation After Catheter Ablation
Evaluation of the predictive value of serum levels of adipocytokines and primary phase reactant for recurrent atrial fibrillation (RAF) after catheter ablation in 26 patients had persistent and 91 patients had paroxysmal AF. During 12-m follow-up, 41 patients had RAF (35%). Patients had RAF were significantly older, had significantly higher BMI, lower ejection fraction and wider maximal left atrial diameter (LAD). Serum hs-CRP, IL-6, TNF-α, visfatin, and adiponectin levels were significantly higher in patients developed. Elevated serum levels of TNF-α, visfatin and adiponectin are a significant positive predictors for RAF.
Objectives: Estimation of serum levels of visfatin, adiponectin, tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6) and high-sensitivity C-reactive protein (hs-CRP) in patients had atrial fibrillation (AF) resistant to medical treatment and assigned to catheter ablation (CA) to evaluate these biomarkers as predictors for recurrent AF (RAF). Patients & Methods: 117 patients; 26 patients had persistent and 91 patients had paroxysmal AF underwent had clinical and echographic evaluations and gave blood samples for ELISA estimation of serum levels of studied cytokines. CA was performed through isolation of all pulmonary veins according to the stepwise procedure of ablation. Patients were re-evaluated every three months till 12-m follow-up for post-procedural RAF. ;
