Long-term exposure to ambient ozone appears to accelerate arterial conditions that progress into cardiovascular disease and stroke, according to a new University at Buffalo study. The research is the first epidemiological study to provide evidence that ozone might advance subclinical arterial disease—injuries that occur to the artery walls prior to a heart attack or stroke—and provides insight into the relationship between ozone exposure and cardiovascular disease risk.
