摘要:

背景:越来越多研究表明,心房纤维化是多种神经体液介质相互作用引起的,其中包括转化生长因子β1、肾素-血管紧张素-醛固酮系统、半乳糖凝集素3、炎症递质、松弛素等。

 

目的:探讨上述神经体液介质与心房纤维化的关系及在心房结构重构及房颤发生发展中的作用。

 

方法:应用计算机检索万方数据库及PubMed数据库2000至2014年文献,中文检索词为“心房纤维化,结构重构,房颤,转化生长因子β1,肾素-血管紧张素-醛固酮,半乳糖凝集素3,炎症,松弛素”;英文检索词为“myocardial fibrosis,Structural remodeling,Atrial fibrillation,RAAS,Galectin-3,Inflammatory mediators,relaxin”,依据纳入排除标准选择42篇文献进行归纳总结。

 

结果与结论:通过分析影响心房纤维化的诸多因素,可以发现促进纤维化发生的各因子间并不是绝对孤立的,而是以一定方式相互增强或相互抑制的,其中转化生长因子β1在各种机制中起着核心作用。各个信号传导途径有不同的侧重,各个信号途径之间亦存在着交叉作用,加深了心房纤维化发病机制的复杂性。心房纤维化会导致局部区域的传导异质性,引起单向阻滞和多子波折返,促进房颤发生。

Abstract:

BACKGROUND: More and more studies have shown that atrial fibrosis is caused by the interaction of multiple neurohormonal media, including transforming growth factor-β1, rennin-angiotensin-aldosterone system, galectin 3, inflammatory mediators, relaxin.

OBJECTIVE: To investigate the relationship between these neurohormonal media and atrial fibrosis as well as the role in the occurrence and development of atrial structural remodeling and atrial fibrillation.
METHODS: PubMed and CNKI databases were searched by computer for relevant articles published from 2000 to 2014. The keywords were “atrial fibrosis, structural remodeling, atrial fibrillation, transforming growth factor-β1, rennin-angiotensin-aldosterone, galectin-3, inflammation, relaxin” in Chinese and “myocardial fibrosis, structural remodeling, atrial fibrillation, RAAS, galectin-3, inflammatory mediators, relaxin” in English. According to the inclusion and exclusion criteria, 46 articles were included finally.
RESULTS AND CONCLUSION: By analyzing the many factors that influence atrial fibrosis, we can find that the factors promoting fibrosis are not absolutely isolated, but mutually enhance or inhibit each other in a certain manner, and wherein the transforming growth factor-β1 plays a central role in various mechanisms. Various signaling pathways have different emphases, and there is also a cross-interaction among these signaling pathways deepens the complexity of the pathogenesis of atrial fibrosis. Atrial fibrosis can lead to conduction heterogeneity in the local area, and induce unidirectional conduction block and multiple wavelet reentry, thereby developing atrial fibrillation.
