Air pollution in India related to a heart attack – Health Updates

Researchers have discovered that air pollution in India is associated with an increased risk of cardiovascular diseases (CVD) such as stroke and heart attack.

Researchers who conducted a study in a peri-urban area of ​​southern India found that air pollution in the country is associated with an increased risk of cardiovascular disease (CVD).

The study shows that people most exposed to fine particles have a higher CIMT index (thickness of the carotid intimate media), a marker of atherosclerosis, which means that they have a higher risk of developing cardiovascular diseases such as stroke or heart attack.

Air pollution in India related to a heart attack – Health Updates

Our findings highlight the need for further studies on air pollution in low and middle-income countries, since the conclusions may differ considerably from studies in high-income countries due to differences in population characteristics and levels and sources of air pollution, “he said. researcher Cathryn Tonne of the Institute of Global Health of Barcelona (ISGlobal).

The study was published in the International Journal of Epidemiology.

Previous studies indicate that inflammation and atherosclerosis are probably responsible for the association between long-term exposure to air pollution and cardiovascular disease and mortality.

Study methodology

For the findings, the research team chose India, a low middle-income country with high levels of air pollution.

The study was conducted with 3,372 participants from a peri-urban region of Hyderabad, Telangana, in southern India.

The research team measured the IACML and estimated exposure to air pollution using an algorithm called land-use regression (LUR) that is frequently used to predict the number of fine particles (suspended particles with a diameter less than 2.5 µm) in high-income countries.

Participants also provided information on the type of cooking fuel they used.

Findings of the study

The results indicate that the high annual exposure to environmental fine particles was associated with a higher IACML, particularly in men, participants over 40 years of age or those with cardiometabolic risk factors.
