Secondhand smoke not only damages the delicate cells that line blood vessels but also disrupts the body's natural repair mechanism for those cells, a new study shows.
The research was done because there still are skeptics who doubt the health value of public smoking bans, said study co-author Stanton A. Glantz, professor of medicine at the University of California, San Francisco, Center for Tobacco Control Research and Education.
"There still are some people out there saying these effects [from smoking bans], seen in terms of reduced heart attacks and an immediate drop in heart attacks, are just not feasible," Glantz said.
The findings were expected to be published in the May 6 issue of the Journal of the American College of Cardiology.
