People who pursue their regular physical activity may have reduced the risk of initial and recurrent heart attack, even in areas with moderate to high traffic pollution, a new study suggests.
The results suggest that higher levels of nitrogen dioxide (NO2), a traffic-generated pollutant, were associated with more heart attacks, but the risk was lower in physically active people.
"Our study shows that even physical activity during exposure to air pollution, cities with levels similar to those in Copenhagen, can reduce the risk of heart attack," said the l & # 39; Author Nadine Kubesch of the University of Copenhagen.
For the study, published in the Journal of the American Heart Association, researchers in Denmark, Germany, and Spain have assessed levels of physical activity in outdoors (sports, cycling, walking and gardening) and NO2 exposure in 51,868 adults aged 50 to 65 years. The researchers also compared self-reported activities and lifestyle factors to heart attack and to estimate the average NO2 exposure, they used national road pollution monitoring data for each participant.
31 percent for recurrent heart attacks and 58 percent when all four types of physical activity (totaling four hours per week or more) were combined, regardless of air quality. .
The researchers said that the 15% reduction rate of initial heart attacks was 15% lower than that of cycling, compared with 17% for participants with low NO2 residential exposure. risk of first heart attack and 39 percent for recurrent heart attack, they added.- IANS
