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.

Long-term ozone exposure may increase risk of death from respiratory causes - 0 views

    MedWire News: Long-term exposure to ozone is associated with an increased risk of death from respiratory causes, researchers have found.\n\nA two-pollutant model in the study, published in the New England Journal of Medicine, showed that levels of fine particulate matter less than 2.5 µm in diameter (PM2.5) were associated with death from cardiovascular causes, whereas increased ozone concentrations were associated with an increased risk of death from cardiopulmonary causes.
