Abstract 12463: Smoking Ban in Public Areas is Associated With Reduced Incidence of Hospital Admissions Due to ST-elevation Myocardial Infarctions in Non-smokers -Results From the Bremen STEMI Registry-
Background: Since 2006 data from all patients in the region of Bremen in northwest Germany (est: 800 000 inhabitants) with ST-elevation myocardial infarction (STEMI) have been centrally collected in the Bremen STEMI-registry. The present study analyzed registry data from 2006 to 2010 on the background of the commencement of an anti-smoking act (end of 2007), which widely banned tobacco smoking from public areas in the region of Bremen.
Methods: Between January 2006 and December 2010 data from the STEMI-Registry was analyzed focusing on date of admission, age, gender, cardiovascular relevant comorbidities and prior nicotin consumption of pts.
Results: Between 2006 and 2010 a total of 3549 pts with STEMI were admitted in the Bremen heart center. When comparing the years before and after the commencement of the law there was a decline from mean 65±11 STEMI/month in 2006-2007 to 55±10 STEMI/mo in 2008-2010, (-16%), p<0.01. Focusing on the group of pts with a smoking habit prior to a myocardial infarction the mean number of STEMI/mo slightly increased: 25/mo in 2006-2007 to 26/mo in 2008-2010, p=0.8. The group of non-smokers however benefits significantly with a decrease in the mean number of STEMI/mo from 39±8 in 2006-2007 to 29±7 in 2008-2010, (-26%), p<0.001 . In a multivariate analysis only non-smokers independent of age, gender and relevant comorbidities show a significant decline in STEMI-incidence after the smoking ban. (Figure 1). When focusing on the younger non-smoking patients (≤65 years) with STEMI an even steeper decline in the mean STEMI/mo can be observed: 13/mo in 2006/2007 vs. 9/mo in 2008-2010, (-32%), p<0.001.
Conclusions: The Bremen STEMI registry reveals over a time period of 5 years a reduction in the incidence of STEMI, which was at least partially associated with the commencement of an anti-smoking act. Non-smokers and especially younger non-smokers benefit most from the commencement of the law indicating the harmful effect of passive smoking.
