Heart attacks dropped by one-third in one county in Minnesota after two
smoke-free workplace ordinances went into place, a new study
shows.
The lead researcher on the work said that decline was likely due to less
secondhand smoke exposure in restaurants and bars, as smoke can trigger
heart problems due to its effects on arteries and blood clotting.
But another tobacco expert questioned whether the drop
in heart attacks could be clearly attributed to the two ordinances, which banned
smoking in restaurants starting in 2002 and then in
all workplaces, including bars, in 2007.
Researchers from the Mayo Clinic in Rochester, Minnesota found that in the 18
months before the first ordinance was enacted, the rate of heart attacks in
Olmsted County was 151 for every 100,000 people. By the 18 months following the
second ordinance, that fell to 101 per 100,000 people.
Dr. Richard Hurt said a few other studies, including one from Montana, have
also suggested smoke-free workplace laws could impact heart attack rates.

Il commento del dottor Beatrice:
Lo studio dimostra che la richiesta dell'opinione pubblica a sostegno di norme
che vietino il fumo anche il luoghi aperti come stadi e parchi non e'
insensata. Purtroppo questo cozza con alcuni comportamenti privati,per esempio
in meta' delle famiglie italiane si può fumare in casa dove si vuole. C'e
bisogno di un aumento di consapevolezza e di crescita comune, collettiva, sull '
importanza del bene individuale salute. In ogni caso meno si e' esposti meglio
e', sempre.
