Abstract:
Objective To investigate the independent factors associated with the apex of left atrial appendage(LAA) spontaneous echo contrast (SEC) in patients with valvular atrial fibrillation (VAF). Methods Seventeen normal subjects and 21 patients with VAF were included. Plasma fibrinogen (Fg),vov Willebrand factor (vWF),D-dimer (DD),P-selectin,thrombin-antithrombin complexes (TAT) and plasminogen activator inhibitor-1(PAI-1) were measured. The apex of LAA SEC was assessed quantitatively by integrated backscatter (IBS). LAA flow and pulmonary venous flow were detected by transesophageal echocardiography. Results Fg,vWF,DD,TAT and PAI-1 were increased significantly in patients with atrial fibrillation compared with control ( P
