Acute Effects of Air Pollution on Ischemic Heart Disease Hospitalizations: A Population-Based Time-Series Study in Wuhan, China, 2017–2018

Abstract

Evidence of the acute effects of air pollutants on ischemic heart disease (IHD) hospitalizations based on the entire population of a megacity in central China is lacking. All IHD hospitalization records from 2017 to 2018 were obtained from the Wuhan Information Center of Health and Family Planning. Daily air pollutant concentrations and meteorological data were synchronously collected from the Wuhan Environmental Protection Bureau. A time-series study using generalized additive models was conducted to systematically examine the associations between air pollutants and IHD hospitalizations. Stratified analyses by gender, age, season, hypertension, diabetes, and hyperlipidemia were performed. In total, 139,616 IHD hospitalizations were included. Short-term exposure to air pollutants was positively associated with IHD hospitalizations. The age group ≥76 was at higher exposure risk, and the associations appeared to be more evident in cold seasons. PM2.5 and PM10 appeared to have greater effects on males and those without hypertension or diabetes, whereas NO2 and SO2 had greater effects on females and those with hypertension or diabetes. The risk of IHD hospitalization due to air pollutants was greater in people without hyperlipidemia. Our study provides new evidence of the effects of air pollution on the increased incidence of IHD in central China.

Long-Term Air Pollution Exposure and Ischemic Heart Disease Mortality Among Elderly in High Aging Asian Economies

“…Reduced particulate matter concentrations, however, are related to reductions in IHD mortality in as little as a few years. In this view, the improvement in quality of life and related health outcomes owing to lower concentrations of air pollutants might be seen by the population in a few years, essentially leading to the adoption of more rigorous policy choices on air quality in most parts of the world (9,13,45).…”

Health and economic impacts of ambient air pollution on hospital admissions for overall and specific cardiovascular diseases in Panzhihua, Southwestern China

“…So et al [ 61 ] investigated the effects of air pollutants on the risk of ischaemic heart disease admissions in South Korea and reported that one-month exposure to SO 2 was related to 1.36-fold higher odds for ischaemic heart disease and one-year exposure to SO 2 and PM 10 was associated with 1.58 and 1.14-fold higher odds for ischaemic heart disease. One study conducted in China [ 62 ] also observed significant and positive correlations between admissions for ischaemic heart disease and short-term exposure to air pollutants.…”

A mobile car monitoring system as a supplementary tool for air quality monitoring in urban and rural environments. The case study from Poland

“…For that reason informing communities about bad air quality episodes should be regarded as a duty not a privilege rendered only to chosen ones. Multiple research links air pollution to respiratory diseases, including chronic obstructive pulmonary disease (COPD) 4 , asthma [5][6] ), lung cancer [7][8] , ischemia heart disease [9][10] , or even urinary bladder cancer 11 . Moreover, prolonged exposure to the air pollution can cause DNA damage 12 , oxidation stress and might even be associated with the brain damage, Alzheimer's disease (AD) and other neurodegenerative disorders [13][14] .…”
