主要空气污染物对缺血性卒中发病风险的影响及其作用机制

Effect of major air pollutants on the risk of ischemic stroke onset and its mechanism of action

缺血性卒中的死亡率和残疾率均很高。多项流行病学研究证实，空气污染物可增高缺血性卒中的患病率或入院率。空气污染物主要包括二氧化硫、二氧化氮、细颗粒物、一氧化碳、臭氧。文章就各种主要空气污染物的主要来源、对缺血性卒中发病风险的影响及其可能机制进行了综述。

The mortality and disability of ischemic stroke are high. A number of epidemiological studies have confirmed that air pollutants can increase the prevalence or admission rate of ischemic stroke. Air pollutants mainly include sulfur dioxide, nitrogen dioxide, fine particles, carbon monoxide, and ozone. This article reviews the main sources of various major air pollutants, the effect of major air pollutants on the risk of ischemic stroke onset, and the possible mechanisms.
