Role of fibroblasts in the development of atrial fibrillation / 医学研究生学报

ABSTRACT

Influenced by a variety of pathologic factors, cardiac fibroblasts can transdifferentiate into myofibroblasts and pro-liferate excessively, followed by an overdue secretion of extracellular matrix ( ECM) .This process involves complicated signaling path-ways and electrophysiological mechanisms and may result in atrial fibrosis and contribute to atrial remodeling in structure, function and electrophysiological signaling, which is considered as a most important phase of atrial fibrillation.This review focuses on the role of fi-broblasts in atrial fibrosis, atrial remodeling, and the development of atrial fibrillation.
