LONDON: Long-term exposure to polluted air increases the risk of heart disease many times over, but even a slight reduction in pollution reduces the risk of heart disease.
The researchers based their findings on data from 157,000 participants aged 35 to 70 from 21 countries. Research has shown that an increase of 10 micrograms per square meter in PM2 point five pollution increases the incidence of heart disease by up to 5%. PM2.5 refers to the pollution caused by particles of 2.5 microns in volume.
To find out the level of PM2.5 around the world, the researchers looked at the details of different countries and concluded that 14% of the heart attack cases recorded are directly related to air pollution.
Perry Hestad, an environmentalist who oversaw the study between 2003 and 2018, said the study showed a direct link between air pollution and a heart attack or stroke. Is found.
PM2.5 particles are formed by fumes from car engines and coal-fired plants. The volume of these particles is so small that they easily enter the lungs through inhalation where they cause permanent inflammation.
However, according to experts, the good news is that if the air pollution caused by these particles is reduced, it will also have a very positive effect on heart disease.
According to Perry Hastad, we could not say for sure before this study. According to some research, the positive effects of air pollution will require extraordinary measures to reduce air pollution in developing countries because of the abundance of air pollutants.
