[摘要] 目的 探讨白细胞介素-6、8(IL-6、IL-8)和基质金属蛋白酶-9(MMP-9)与心房颤动(AF)之间的关系。 方法选取AF患者108例,其中,阵发性AF 48例,持续性AF 33例,永久性AF 27例;另外,窦性心律者45例。采用酶联免疫吸附法检测血清中IL-6、 IL-8、MMP-9水平,评估IL-6、IL-8、MMP-9与AF的相关性。 结果 AF组IL-6、IL-8、MMP-9水平均高于窦性心律组(P<0.05);在IL-6和MMP-9水平方面,永久性AF组高于阵发性AF组和持续性AF组(P<0.05),阵发性AF组和持续性AF组差异无统计学意义(P>0.05);Logistic回归分析结果提示,IL-6水平是AF发生的独立因子(P<0.01)。 结论 AF患者血清IL-6、IL-8、MMP-9水平明显高于窦性心律者,炎性因子可能参与了AF的发生和进展过程。

[Abstract] Objective To probe into the relationship between interleukin-6(IL-6),interleukin-8(IL-8),matrix metalloproteinase-9(MMP-9) and atrial fibrillation(AF). Methods 108 cases of AF patients were selected including paroxysmal pattern(n=48),persistent pattern(n=33),permanent pattern (n=27).45 cases of patients with sinus rhythm were also recruited.The levels of IL-6,IL-8 and MMP-9 in serum were tested by enzyme linked immunosorbent assay in order to compare the levels of these above-mentioned indexes among each group.The correlations between IL-6,IL-8,MMP-9 and AF were evaluated by logistic regression analysis. Results The levels of IL-6,IL-8 and MMP-9 in AF groups were all higher than those of sinus rhythm group(P<0.05).Levels of IL-6 and MMP-9 in permanent AF group were higher than those of paroxysmal AF group and persistent AF group(P<0.05),but the two indexes didn′t display statistical differences in paroxysmal AF group and persistent AF group(P>0.05).Logistic regression analysis results suggested that the level of IL-6 was the independent factors of AF occurrence(P<0.01). Conclusion Levels of IL-6,IL-8 and MMP-9 in serum from AF patients were remarkably higher than those of sinus rhythm people.Inflammatory factors may get involved in the occurrence and persistence of AF.

心房颤动(atrial fibrillation,AF)是临床上最常见且治疗费用昂贵的慢性心律失常疾病。AF是脑卒中最重要的独立危险因素之一,有研究表明,非瓣膜病AF引起脑梗死的发生率是窦性心律的5.6倍,瓣膜病合并AF是窦性心律的17.6倍[1],因此,预防AF的发生迫切需要提上日程。AF的病因除了传统的年龄、高血压、瓣膜病、冠心病等原因外,一些新的危险因素也日益受到重视,如胰岛素抵抗、代谢综合征等。临床已证实炎性因子在AF的发生和维持中起着重要的作用[2]。白细胞介素-6(interleukin-6,IL-6)、白细胞介素-8(interleukin-8,IL-8)、基质金属蛋白酶-9(matrix metalloproteinase-9,MMP-9)作为炎症细胞因子,在免疫应答和炎症反应的过程中扮演着重要的角色,同时参与了炎性损伤的全部过程。本次研究测定了AF患者IL-6、IL-8、MMP-9水平,从炎症因子的角度探讨AF的发病机制,为AF的防治提供理论基础。
1 资料与方法
1.1 一般资料
108例AF患者为2012年1月~2013年10月在吉林市中心医院心血管内科住院患者。AF的诊断及分类按 2010年ESC制订的标准[3]。其中,阵发性AF 48例,持续性AF 33例,永久性AF 27例,45例窦性心律患者为同一期间住院的无AF病史患者。……
