People at risk of heart disease should avoid secondhand smoke because
it increases the risk of acute myocardial infarction (MI), the US Centers
for Disease Control and Prevention (CDC) warns in a commentary in the April
24 issue of the British Medical Journal (BMJ. 2004;328:980-983).
The warning accompanied a study concluding that smoking bans at work
and in public places may be associated with reducing morbidity from heart
disease (BMJ. 2004;328:977-983).
