Smoking ban leads to major drop in heart attacks
ATLANTA – A smoking ban in one Colorado city led to a dramatic drop in heart attack hospitalizations, according to a new study that is considered the best and longest-term research to show such a link.
The rate of hospitalized cases dropped 41 percent three years after the ban of workplace smoking in Pueblo, Colo., took effect. There was no such drop in two neighboring areas, and researchers believe it’s a clear sign the ban was responsible.
The study suggests that secondhand smoke may be a terrible and under-recognized cause of heart attack deaths in this country, said one of its authors, Terry Pechacek of the U.S. Centers for Disease Control and Prevention.
At least eight earlier studies have linked smoking bans to decreased heart attacks, but none ran as long as three years. Some critics had questioned whether a ban could have such an immediate impact, and suggested other factors could have driven the declines.
