China: air pollution on ischemic heart disease hospitalizations

Air pollution is a factor that is negatively affecting our life, especially in highly industrialized and urbanized areas. Some poles, especially in China, show another presence of pollutants in the air, such as poor air quality.

The situation is complicated in many Chinese cities, such as Beijing or Shanghai, but also in Wuhan, a city hit hard during the Covid-19 pandemic. And China has seen an increase in air pollution for years, despite all the efforts of the Chinese authorities to limit it.

The study: Acute Effects of Air Pollution on Ischemic Heart Disease Hospitalizations: A Population-Based Time-Series Study in Wuhan, China, 2017-2018, published on the International journal of environmental research and public health, explained: "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."

The research also said: "Stratified analyzes 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. "
