Pollution from automobile traffic is linked with a significantly increased risk of heart attacks, according to a study published Oct. 11
An increase in traffic near the home was associated with a 4 percent increase in the risk of having a heart attack, and living near a major road was associated with a 5 percent increase, according to the study by six Massachusetts researchers.
The study was published online in Environmental Health Perspectives, a journal of the National Institute of Environmental Health Sciences. The six researchers were from the Harvard School of Public Health, Beth Israel Deaconess Medical Center, and University of Massachusetts Medical School.
"We observed a significant association between exposure to traffic near the place of residence and the occurrence of acute myocardial infarction," the study said.
The research team analyzed the pollution levels near homes of 5,049 people in Worcester, Mass., who had heart attacks between 1995 and 2003 and compared that information to pollution of 10,277 people who did not have a heart attack.
