Smoke-free workplace laws may be related to better cardiac health

Should government impose workplace health rules? As explained here, laws requiring smoke-free workplaces may significantly improve cardiac health. An excerpt:

Researchers at the Mayo Clinic in Rochester, Minn. looked at the number
of heart attacks among residents of Olmsted County, Minn. that occurred
18 months before and after implementation of laws banning smoking in
restaurants in 2002, and the 18 months before and after those laws were
extended to include all workplaces, including bars, in 2007. They found
that the incidence of heart attack declined by a third (33 percent) from
the start of the study to the end (i.e., from the 18 months before the
first laws to the 18 months after the second laws went into effect).

Get details on the study, which has been published in the Archives of Internal Medicine.
