Acute myocardial infarction hospitalization statistics: apparent decline accompanying an increase in smoke-free areas.
Recent research suggests that the introduction of antismoking regulations reduces the incidence of acute myocardial infarction (AMI). The aim of this study was to analyze changes in AMIs in the Barcelona metropolitan area in Spain following implementation of the 2006 antismoking law. Data was collected on all discharges from hospitals funded by the Catalan Health Service in 2004-2006. All patients aged over 24 years who lived in the area and who received a primary diagnosis of AMI were included. Annual AMI hospitalization rates, with 95% confidence intervals, were estimated for each year and stratified according to age and sex. The 2004 rate was higher than the 2005 rate for most age and sex groups, though confidence intervals overlapped. The 2006 rates were lower than the 2005 rates for all age groups, and there was no overlap in confidence intervals in men. In conclusion, the introduction of regulations on smoke-free areas was accompanied by a reduction in the AMI hospitalization rate.
