Even low levels of air pollution can hurt the heart and lungs

Breathing In air with even lower levels of pollution poses a threat to the elderly heart And lung, New research warns.

Researchers have analyzed the medical records of more than 63 million Medicare patients from 2000 to 2016. They found that long-term exposure to low levels of air pollution could increase the risk. pneumonia, heart attack, stroke And irregular heart Rhythm known as Atrial fibrillation (((a-fib).

A threat to the hearts of seniors lung According to a survey published in the journal on February 22, it was also seen at levels of air pollution below national standards. circulation..

Researchers evaluated three components of air pollution: particulate matter, nitrogen dioxide, and ozone. Studies have shown that each unit of increased levels of these pollutants is associated with thousands of hospitalizations per year.

Survey results show that air pollution should be considered a risk factor for Heart disease Said the researchers, lung disease.

Mahdi Danesh Yazid, a postdoctoral researcher at Harvard University’s School of Public Health, said:

“Our study found harmful effects below current US standards, so air pollution should be considered a risk factor for cardiovascular and respiratory disease by clinicians, and policy makers should consider air. We need to rethink our current standards for pollutants, “she added in a journal news release.

Researchers said air pollution can harm the heart and lungs by causing inflammation of the heart and system.

For certain pollutants heart attack, stroke, a-fib And Flutter, the same as pneumonia It was associated with long-term exposure to particulate matter.

Long-term exposure to nitrogen dioxide was associated with increased risk stroke And a-fib..

pneumonia It was the only condition associated with long-term exposure to ozone. Researchers said there were no national guidelines for safe or dangerous long-term ozone levels.

“If we limit our analysis to individuals exposed only to low levels of air pollution, we find that all survey results increase the risk of hospitalization, even at concentrations below current national standards.” Danesh Yazdi said.

More than half of the research population is exposed to what US benchmarks consider to be low levels of these pollutants, she said.
