Inflammatory indexes such as high-sensitive C-reactive protein （hs-CRP） have been related to the development and persistence of AF. However, the role of inflammation in the atrial electrophysiological remodeling indexed by P-wave dispersion （Pa） remains unclear. Methods： The study consisted of 71 patients with lone paroxysmal AF （AF group） and 71 age- and gender-matched controls of paroxysmal supraventricular tachycardia without history of AF （control group）. Electrocardiography, P hs-CRP, and other clinical characteristics were compared between the two groups. Results： There was no significant difference between the two groups regarding age, gender, hyperlipidemia, etc. Compared to controls, left atrial diameter （44 ± 7 vs 39 ± 7 mm）, Pd （49 ± 13 vs 26 ± 8 ms）, and hs-CRP （2.17 [1.46-2.89] vs 1.12 [0.74-1.41] rag/L） were increased （P 〈 0.05）, respectively. Linear regression identified hs-CRP as an independent correlation ofPd level both in the total population and the AF group （r = 0.464 and 0.313; P 〈 0.001, respectively）. Multiple logistic regression revealed hs-C RP as an independent determinant of AF （odds ratio [OR] =l 5.430, 95% confidence interval： 6.031-39.476： P 〈0.001）. Further adjusted tbr Pd, both Pd and hs-CRP were independent predictors for AF, but the OR for hs-CRP in predicting AF has been attenuated from 15.430 to 6.246. Conclusions： In lone AF, P and plasma hs-CRP concentration are inter-associated and related to AF. The interaction between hs-CRP and AF may be mediated by Pe, suggesting an important role of inflammation in the atrial electrophysiological remodeling predisposing to AF.展开更多
