Abstract
Atrial fibrillation (AF) is the most common sustained arrhythmia in clinical practice. Though the pathogenesis of AF is complex and is not completely understood, many studies suggest that oxidative stress is a major mechanism in pathophysiology of AF. Through multiple mechanisms, reactive oxygen species (ROS) lead to the formation of an AF substrate that facilitates the development and maintenance of AF. In this review article, we provide an update on the different mechanisms by which oxidative stress promotes atrial remodeling. We then discuss several therapeutic strategies targeting oxidative stress for the prevention or treatment of AF. Considering the complex biology of ROS induced remodeling, and the evolution of ROS sources and compartmentalization during AF progression, there is a definite need for improvement in timing, targeting and reduction of off-target effects of therapeutic strategies targeting oxidative injury in AF.
期刊介绍：
The Journal of Molecular and Cellular Cardiology publishes work advancing knowledge of the mechanisms responsible for both normal and diseased cardiovascular function. To this end papers are published in all relevant areas. These include (but are not limited to): structural biology; genetics; proteomics; morphology; stem cells; molecular biology; metabolism; biophysics; bioengineering; computational modeling and systems analysis; electrophysiology; pharmacology and physiology. Papers are encouraged with both basic and translational approaches. The journal is directed not only to basic scientists but also to clinical cardiologists who wish to follow the rapidly advancing frontiers of basic knowledge of the heart and circulation.
