A Lethal Combination

SAN FRANCISCO () -- Heart attacks that kill non-smokers chronically exposed to secondhand tobacco smoke may result from a long disease process caused by smoke and high cholesterol acting together to damage cells lining artery walls, researchers said Monday.


Some studies indicate that each year 50,000 non-smokers die from heart attacks attributable to secondhand smoke, the researchers at the University of California at San Francisco (UCSF) said. Heart disease greatly outstrips lung cancer as the most deadly health risk faced by non-smokers exposed in this way, they said.
