Death risks higher for heart attack survivors living near major roadways

Health Care, Medicine Comments Off

Heart attack survivors who live about 100 meters or less from a major roadway face increased risk of death from all causes, according to new research in the American Heart Association’s journal Circulation.

In the Determinants of MI Onset Study of 3,547 heart attack survivors (average age 62), researchers found:

  • Those living less than 100 meters from the roadway have a 27 percent increased risks of dying over 10 years than those living at least 1,000 meters away.
  • Those living 100 to 199 meters from the roadway have a 19 percent increased risks of death.
  • Those living 200 to 999 meters from the roadway have a 13 percent increased risk of death.

There is exposure to a combination of air pollution near these roadways and other exposure, such as excessive noise or stress from living close to the roadway, that may contribute to the study findings,” said Murray A. Mittleman, M.D., Dr. PH, study author and director of the Cardiovascular Research Unit at Beth Israel Deaconess Medical Center in Boston, Mass.
