A new medical study conducted in Canada has declared air pollution hazardous to heart health.
Experts state that air pollution not only harms our lungs and respiratory system but can also negatively affect the heart. The findings were published in the medical journal Radiology.
The study, conducted by the University of Toronto, found that long-term exposure to air pollution can lead to damage to the heart.
It is worth noting that cardiovascular diseases, including heart attacks and strokes, are the leading causes of death globally. Although earlier studies had hinted at a link between air pollution and heart diseases, the underlying reasons remained unclear.
In this latest research, cardiac MRI scans were used on 493 patients and 201 healthy individuals to examine the effects of fine particulate matter from air pollution on the heart.
Results showed that prolonged exposure to polluted air can make it harder for the heart to pump blood effectively, indicating early damage to the heart.
According to researchers, this may explain why people exposed to air pollution are more likely to suffer from heart-related issues—especially women, smokers, and individuals with high blood pressure.
The study strengthens the evidence that air pollution is a significant risk factor for cardiovascular diseases.
Researchers further stated that even moderate increases in air pollution can have considerable negative effects on heart health. Air quality plays a key role in altering the structure of the heart.
They emphasized that individuals exposed to polluted air for extended periods should undergo regular heart check-ups. Notably, Canada has relatively low levels of air pollution compared to many other countries, highlighting that even minimal exposure can pose risks.
The researchers concluded by stressing the need for public health measures to protect people from heart diseases caused by air pollution.
