The results of the study by Hurt et al2 highlight some of the potential benefits of 100% smoke-free policies in workplaces, restaurants, and bars: significantly decreased incidence of myocardial infarction and a trend toward decreased sudden cardiac death. The authors used comprehensive access to medical records in a single system, a substantial follow-up period, and rigorous epidemiologic criteria to record and validate diagnoses of myocardial infarction and sudden cardiac death in Olmstead County, Minnesota. They found that, after implementation of smoke-free workplace laws, the incidence of myocardial infarction declined significantly (33%) and there was a trend of decreased incidence of sudden cardiac death, while the prevalence of other risk factors for cardiac disease remained unchanged or increased.
