People health loss in a certain city due to coronary heart disease caused by atmospheric particulate matter PM2.5
Objective To understand the health loss of people in a certain city due to coronary heart disease caused by atmospheric particulate matter PM2.5 in recent ten years.Methods The data of atmospheric particulate matter PM2.5 from 2011 to 2020 and the death data of coronary heart disease of the residents were collected,and the years of early life lost(YLL)caused by coronary heart disease was calculated,the short-term exposure and long-term effects of atmospheric particulates was analyzed,and the health improvement of patients with coronary heart disease under the first level national standard of PM2.5(μg/m3)was evaluated.Results In recent ten years,the total number of coronary heart disease deaths caused by PM2.5 increased from 747 in 2011 to 890 in 2020,with an increase of 19.14％.The life loss of coronary heart disease caused by PM2.5 in recent ten years was 106 840.48 YLLs.From 2011 to 2020,the average life expectancy loss of coronary heart disease attributed to PM2.5 in the city was 0.20 years,0.29 years for men and 0.12 years for women,and for Men it was 2.42 times of women.According to the first level standard of the National Ambient Air Quality Standard,the annual average atmospheric PM2.5 was 15 by adjusting the level of μg/m3,4 375 deaths of coronary heart disease in the city in recent 10 years could be reduced,49 001.61 YLLs could be reduced,and life expectancy could be increased by 0.09 years.Conclusion Coronary heart disease can lead to serious health loss in local residents,and the residents in this city can obtain good health benefits after reducing the concentration of PM2.5,which indicates that the reduction of PM25 concentration may decrease the cardiovascular disease mortality in our city.
