Abstract

There is increasing evidence from molecular studies to support the role of inflammation and increased oxidative stress that produce structural and electrical atrial remodeling to produce Atrial Fbrillation (AF). Oxidative damage to cardiomyocytes yields chemical substances that are secreted in urine. These substances can serve as biomarkers that can be measured, potentially allowing clinicians to quantify oxidative damage to the heart.

Keywords: Atrial fibrillation, Oxidative stress, Urinary biomarkers, Inflammation, CRP, IL-6, Isoprostanes, 8-OHdG, Antioxidant, NADPH oxidase.
