PM2.5致心血管系统损伤及机制研究进展
摘 要:
细颗粒物(particulate matter, PM2.5) 是一种严重的环境污染物质。它对机体多系统都有不良影响,而心血管系统是其主要目标,因此PM2.5 暴露对心血管系统的影响越来越受到人们的关注。许多研究表明PM2.5 与心血管疾病(cardiovascular disease, CVD) 的发病率和死亡率之间具有明确的因果关系。PM2.5 通过氧化应激、炎症、线粒体损伤、细胞凋亡等机制对心血管系统造成损伤,成为CVD 的主要死亡危险因素。本文从流行病学、动物、细胞水平的角度总结了PM2.5 诱导CVD 机制的研究现状,为更好地了解心血管致病机理,提高公众对PM2.5 对CVD 危害的认识,为预防、管理、治疗PM2.5 引起的CVD 提供科学依据。

Abstract:
Cardiovascular system is the main target of fine particulate matter (PM2.5), a serious environmental contaminant, which has adverse health effects on multiple body systems. Therefore the influence of PM2.5 exposure to cardiovascular system has drawn more and more attention. A unequivocal link between PM2.5 and morbidity and mortality of cardiovascular diseases (CVD) has been proved by a number of studies. Cardiovascular system injury was induced by PM2.5 through mechanisms of oxidative stress, inflammation, mitochondrial dysfunction and cell apoptosis, etc., thus PM2.5 has become the main risk factor for CVD death. Current researches on mechanisms of PM2.5-induced CVD were summarized from the perspectives of human epidemiology, animal and cell, to improve the public awareness to CVD induced by PM2.5 and provide a scientific basis for the prevention, management and treatment of CVD caused by PM2.5.
