Abstract：Objective To investigate the correlation between left atrial diameter (LAD), serum uric acid (UA) level and atrial fibrillation (AF). Methods 239 patients with AF (case group) and 60 patients without AF (control group) were recruited from Jan 2016 to Jun 2016 in department of cardiology, Shenzhen People's Hospital. The medical records and laboratory results were collected. The left ventricular end systolic LAD, left ventricular end diastolic diameter (LVDD) and left ventricular ejection fraction (LVEF) were measured by using an ultrasonic diagnostic instrument. Logistic regression was used to analyze the risk factors of atrial fibrillation. Results The TC, TG and LEVF of the patients in the case group were significantly lower than those in the control group (all P<0.05). The UA and LAD in the case group were significantly higher than those in the control group (all P<0.05). Logistic regression analysis showed that age, UA and LAD were risk factors of atrial fibrillation. The levels of UA and LAD in patients with paroxysmal AF and persistent AF were significantly higher than those in control group (all P<0.05), and the levels of UA and LAD in patients with persistent AF were higher than those with paroxysmal AF (all P<0.05). Conclusion Left atrial diameter and serum uric acid level are independent risk factors of atrial fibrillation, and may be related to the progress of atrial fibrillation, the mechanism needs to be further studied and confirmed.
