Christensen, T.M.; Moller, L.; Jorgensen, T.; Pisinger, C., "The impact of the Danish smoking ban on hospital admissions for acute myocardial infarction," European Journal of Preventive Cardiology [Epub ahead of print], August 31, 2012.

This study examined the impact of the nation's smokefree air law on heart attack rates and concluded that, "A significant reduction in the number of AMI-admissions was found already one year before the SB [smoking ban] after adjustment for the incidence of T2D [type 2 diabetes]. The results differ from most results found in similar studies throughout the world and may be explained by the incremental enactment of SBs in Denmark and the implementation of a nation-wide ban on industrially produced trans-fatty acids in food in 2004."
