ABSTRACT
Objective To investigate the level and the source of inflammatory factors in patients with paroxysmal atrial fibrillation.Methods Thirty patients with paroxysmal atrial fibrillation were selected as observation group,and 20 cases of patients with paroxysmal supraventricular tachycardia were selected as control group.The blood samples of coronary sinus,right atria,left atria and femoral vein were consecutively collected during the procedure of radiofrequency ablation.The level of tumor necrosis factor (TNF)-α,soluble tumor necrosis factor receptor-1 (sTNFR1),and interleukin(IL)-6 was detected by ELISA separately and compared between two groups.Results The level of TNF-α and IL-6 of coronary sinus,right atria,left atria and femoral vein in observation group was significantly higher than that in control group [TNF-α:(4.45 ± 1.76) ng/L vs.(0.59 ± 0.36) ng/L,(6.67 ± 1.43) ng/L vs.(0.51 ± 0.30) ng/L,(8.35 ± 2.03) ng/L vs.(0.85 ± 0.50) ng/L,(9.97 ± 2.70) ng/L vs.(0.28 ± 0.29) ng/L,P=0.000;IL-6:(2.02 ± 0.87) ng/L vs.(1.04 ± 0.63) ng/L,(1.51 ± 0.68) ng/L vs.(0.74 ± 0.26) ng/L,(2.00 ± 0.51) ng/L vs.(0.88 ± 0.35) ng/L,(1.32 ±0.47) ng/L vs.(0.48 ±0.28) ng/L,P =0.000].The level of high sensitivity C reactive protein (hs-CRP) in observation group was significantly higher than that in control group [(2.41 ± 1.35) mg/L vs.(1.10 ±0.53) mg/L,P =0.002].The level of TNF-αof left atrium in observation group was significantly higher than that of other three sites (P=0.000).The level of IL-6 in the coronary sinus and femoral vein was significantly increased,compared with that in the right atria and left atria (P < 0.05).The level of sTNFR 1 in the femoral vein,right atria and coronary sinus difference was not statistically significant (P > 0.05),but was significantly higher than that in the left atria(P < 0.05).The level of TNF-α,IL-6 and hs-CRP was correlated with the diameter of left atrium (LAD) (P < 0.01 or < 0.05).The level of sTNFR1 in left atria was positively correlated with LAD,and the level of sTNFR1 in right atria was negatively correlated with LAD (P < 0.01).Conclusions The level of TNF-α,IL-6 and hs-CRP is increased in patients with paroxysmal atrial fibrillation.TNF-α and IL-6 may come from the heart and is related with the enlargement of left atrium.
