According to new research published in the American Heart Association’s journal, Circulation, heart attack survivors living near roadways could face an increased risk of death. The study involved 3,547 people who were hospitalized for heart attack in 64 medical centers across the United States between 1989 and 1996.
Participants that lived less than 100 meters (328 feet) from a roadway have a 27 percent increased risk of dying over the following 10 years than those living 1,000 meters (3,280 feet) away.
While air pollution has already been linked to increased risk of heart attack and stroke, this is the first time it has been suggested that further exposure could result in death.
"We think 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.
Homeowners concerned about the welfare of their loved one can invest in a home air purifier such as the IQAir HealthPro Plus Air Purifier to reduce exposure to deadly toxins.
