Abstract：Objective To investigate the relative risk factors in patients with lone atrial fibrillation (LAF). Methods The patients with LAF treated with radiofrequency ablation (RFA) were chosen as LAF group (n=14), and patients with paroxysmal supraventricular tachycardia (PSVT) treated with RFA at the same time were chosen as control group (n=43) from Jan. 2011 to Jun. 2012. The general clinical data was collected from the patients in two groups, and the changes of age, blood pressure (BP), heart rate (HR), left atrial size, BMI, blood fat and plasma glucose were analyzed. Results Compared with control group, in LAF group left atrial size was largger [(35.93± 5.74) mm vs. (31.20±4.64) mm, P=0.007], levels of BMI (25.70±3.21 vs. 23.49±2.32, P=0.003), LDL-C [(2.85± 0.61) mmol/L vs. (2.23±0.31) mmol/L, P=0.038] and FBG [(5.96±1.64) mmol/L vs. (4.76±0.74) mmol/L, P=0.031] were higher, level of HDL-C [(1.14±0.21) mmol/L vs. (1.49±0.27) mmol/L, P=0.015] was lower, and TC and TG had no significant changes (P>0.05). The left atrial size was positively correlated to BMI (r=0.55, P<0.05), LDL-C(r=0.85, P<0.01) and FBG (r=0.81, P<0.01), and negatively correlated to HDL-C (r=-0.91, P<0.01). Conclusion LAF is not isolated in clinic, and left atrial size, BMI, blood fat and plasma glucose are its relative risk factors.
