The modern lifestyle, despite its many advantages and advantages, compared to the old lifestyle, has harmful effects on public health, revealed by medical studies and research, most of which revolve around the chemical emissions and environmental pollution that people are exposed to in urban life in general.

In the same context, a recent study found that exposure to pollution threatens heart health, as in the following.


Air pollution and heart health


A recent study stated that exposure to air pollution even at levels lower than the air quality guidelines issued by the World Health Organization may lead to a heart attack.

The study found that exposure to any level of four common air pollutants, particulate matter, nitrogen dioxide, sulfur dioxide and carbon monoxide, can lead to the rapid onset of acute coronary syndrome, an umbrella term describing any condition in which the blood supply is blocked. For heart muscle, such as a heart attack or unstable angina, and chest pain caused by blood clots that temporarily block an artery.

The negative effects of air pollution on the cardiovascular system have been well documented, said Dr Haidong Kan, a professor at the Fudan University School of Public Health in Shanghai. But we are still amazed at the very rapid effects.

He added: The other surprise was the non-marginal effects of air pollution, any concentration of air pollutants may lead to the start of a heart attack.


Study details


Researchers analyzed medical data from 1.3 million people treated for heart attacks and unstable angina at 2,239 hospitals in 318 Chinese cities, comparing hourly heart event times with concentrations of fine and coarse particles, nitrogen dioxide, sulfur dioxide, carbon monoxide and ozone. While the short-term exposure to any level of pollutants, the higher the levels of the studied pollutants, as well as the higher the risk of heart attacks.
