Résumé
Exposure to fine particulate (PM2.5) has become a serious environmental risk factor threatening public health. A large number of epidemiological studies have shown that PM2.5 exposure is significantly associated with cardiovascular health. At present, studies have found that PM2.5 components are associated with the incidence and death of cardiovascular metabolic diseases (hypertension, diabetes, coronary heart disease, stroke, etc.), which may be due to the different components of PM2.5 in different regions, which have different effects on cardiovascular health. This article reviews the effects of different components of PM2.5 on cardiovascular metabolic diseases based on their sources and pathogenesis. The limitations of the effects of PM2.5 components on cardiovascular metabolic diseases are also discussed.
