Freeways could increase risk of heart attacks

People who live really close to freeways may run a much higher risk of having a heart attack.

UC Berkeley researchers studied the effects of pollution from auto exhaust on more than 1,000 people who live near freeways in the Los Angeles area.

Researchers say the people living within about 300 feet of the freeway were more than twice as likely than the average person to develop heart disease, but it is too early to draw a cause-and-effect conclusion.
