A study published in the June 9, 2010 edition of the British Medical Journal (BMJ) concluded that following the introduction of smokefree laws in England, there were 1,200 fewer emergency heart attack admissions during a 12-month period. (Sims, M.; Maxwell, R.; Bauld, L.; Gilmore, A., "Short term impact of smoke-free legislation in England: retrospective analysis of hospital admissions for myocardial infarction," British Medical Journal [Epub ahead of print], June 8, 2010.)

In Scotland, a study published in the July 31, 2008 issue of the New England Journal of Medicine, concluded that the nation's smokefree air law had resulted in an overall 17 percent decline in rate of heart attacks, with a 21 percent reduction for people who had never smoked. The study was conducted in nine Scottish hospitals. During the same period, the heart attack rate declined only by 4 percent in England, which had not yet enacted its smokefree air law. This study was orginally presented at an international tobacco conference in October 2007.

Hospitals in north Cumbria reported that the number of heart attacks has dropped nearly in half since the smokefree law took effect.

Hospitals in Wales and England have reported reductions in the number of heart attacks they treat following the implementation of a smokefree air law.

Wales reported a drop of 13 percent between October-December 2006 and October-December 2007.

Hospitals in England reported 1,384 fewer heart attacks (3%) during the nine months after the legislation took effect, compared to the same period the year before.
