Atrial Fibrillation, Endothelial Function
A Case Control Study to Investigate the Possible Association Between Atrial Fibrillation and Endothelium Dysfunction by Using Flow-Mediated Vasodilation Method
Endothelial function is closely related to the hemostasis , vascular tone, and organ perfusion in cardiovascular system, and its dysfunction would cause overactivation of the coagulative system to induce thrombus formation.
