Long-term exposure to high concentrations of PM2.5 significantly increases the risk of cardiovascular disease

, a new study revealed that long-term exposure to high concentrations of fine particulate matter (PM2.5) can significantly increase the risk of cardiovascular disease and death in China's residents. The study was published online in the Journal of the American College of Cardiology.
that the study used international advanced satellite remote sensing intronsic technology to evaluate the long-term exposure levels of atmospheric PM2.5 in the population (2000-2015). The study found that the average annual exposure concentration of atmospheric PM2.5 increased by 10 micrograms per cubic meter, and the risk of cardiovascular disease and death increased by 25% and 16%, respectively, while long-term exposure of atmospheric PM2.5 was the most harmful to the incidence of acute coronary syndrome and death from acute myocardial infarction, increasing the risk by 38% and 52%, respectively. The study also suggests that the cardiovascular health of the elderly and rural residents is greatly affected by air pollution. The study population came from about 120,000 urban and rural residents in 15 provinces and cities in China, and the atmospheric PM2.5 exposure level covered a concentration range of 26 to 114 micrograms per cubic meter.
Commenting on the findings, Rajagopalan, a professor at case Western Reserve University in the United States, said: "This study adds evidence of past high concentrations of air pollution and cardiovascular disease risk and expands our understanding of the morphological characteristics of the relationship between PM2.5 and cardiovascular disease exposure-response curves. In addition, Rajagopalan stressed that the study has some clinical guidance value, suggesting that clinicians should consider air pollution exposure as a risk factor when assessing an individual's risk of cardiovascular disease.
