Traffic Triples Heart Attack Risk - WebMD - 0 views

    March 13, 2009 -- Whether you drive, take the bus, or bicycle, being in heavy traffic triples your risk of heart attack within one hour.

    Air pollution from car fumes is the likely culprit, suggest Annette Peters, PhD, and colleagues at the Institute of Epidemiology, Helmholtz Center, Munich, Germany.

    In a previous study, Peters and colleagues found that a sizeable proportion of heart attacks -- about 8% -- could be attributed to being in traffic.

    To follow up, the researchers interviewed 1,454 people who survived heart attacks. In the hour before their heart attack, many of the survivors had been in heavy traffic.

    Analysis of the data showed that these heart-attack-vulnerable people were 3.2 times more likely to suffer a heart attack if they'd been in heavy traffic in the previous hour.
