Smoking following myocardial infarction: a critical review of the literature.

This paper critically reviews the available research on the effects of smoking cessation following acute myocardial infarction (MI). Studies that have examined the rate of smoking cessation following an MI indicate that approximately 1/3 to 1/2 of the smokers who suffer from MI subsequently reduce or quit smoking. Furthermore, studies that have examined subsequent mortality and morbidity suggest that individuals who quit smoking following MI exhibit lower mortality and morbidity than those who continue to smoke. It is argued that past studies may have overestimated post-MI smoking cessation rates, and by failing to control for a priori differences between quitters and continuing smokers (e.g., MI severity) may have underestimated the negative effects of smoking following MI. Suggestions for future research are proposed.
