CHARLESTON, W.Va. - Estrogen may give women an edge in resisting heart disease that can be caused in part by air pollution, a new West Virginia University study found.

That coincides with a major national study released earlier this year showing older women are at significantly higher risk for heart problems caused by air pollution than other people.>>> Discuss This Story
