Analysis on the levels of C-reactive protein, left atrial diameter, and D-dimer in patients with different types of atrial fibrillation.

Objective To observe the levels of C-reactive protein, left atrial diameter and D-dimer in patients with with different types of atrial fibrillation, and to explore their relationship with atrial fibrillation. Methods Forty-two patients with atrial fibrillation treated in our hospital from January 2009 to March 2012 were enrolled in the study, including 22 cases of persistent atrial fibrillation (persistent AF group) and 20 cases of paroxysmal atrial fibrillation (paroxysmal AF group). Forty-two patients without atrial fibrillation were selected as the control group. The levels of CRP, LAD and D-dimer levels were detected. Results The levels of CRP, LAD and D-dimer in persistent AF group and paroxysmal AF group were significantly higher than those in the control group (P0.05). The levels of CRP and LAD in persistent AF group were significantly higher than that in paroxysmal AF group (P0.05). The D-dimer levels in persistent AF group and paroxysmal AF group showed no statistically significant difference (P0.05). Conclusion The levels of CRP, LAD and D-dimer are associated with atrial fibrillation. Atrial remodeling and inflammatory response play an important role in patients with atrial fibrillation, and D-dimer levels can be used to determine thromboembolic risk of level.
