American scientists from Yale University have identified a link between elevated ozone levels in the air and an increased risk of heart attack in young people. The study was published in the scientific journal GeoHealth.
The team analyzed data from 2,322 patients aged 18 to 55 who had suffered a heart attack. The researchers examined air pollution levels, including ozone and fine particulate matter (PM2.5), near the participants’ homes.
The study found that high ozone levels were associated with an increase in heart attacks 4–5 days after exposure. However, no link was found between PM2.5 and heart attacks.
Researchers analyzed different types of heart attacks separately and found that ozone was most strongly linked to heart problems, such as low blood pressure, that result from reduced oxygen supply.
Scientists also found that the link between ozone and heart attacks may be stronger during warmer months. This is especially concerning given climate change, which is driving up air pollution levels and increasing the frequency of extreme temperatures.
The team plans to continue studying the health effects of air pollution to develop more effective prevention and protection measures.
