Abstract: To observe the D-dimer levels and the numbers of micro-embolic signals (MES) in atrial fibrillation patients with different thromboembolic risk scores. A total of 216 persistent atrial patients were classified according to their different scores with a range of 0 -6.They were also divided into two groups by ≥2 or ＜ 2 according to the CardiacFailure,Hypertension,Age,Diabetes,Stroke 2 (CHADS2) point system.D-dimer levels and the numbers of MES were detected in all patients.A rising trend of D-dimer level and the number of MES was observed with the increases of CHADS2 score. D-dimer level and the number of MES in group 0 or 1 score were significantly lower than those in other high score groups (P ＜ 0.05).And the number of MES in group 5 or 6 score was significantly higher than those in other low score groups (P ＜ 0.05).D-dimer level and the number of MES in the group of ≥ 2 score were significantly higher than those in group ＜ 2 score ( P ＜ 0.01 ).It suggests that D-dimer level and the nunber of MES may reflect the thromboembolic risks in atrial fibrillation patients.
