[Efficacy of an intervention in smoking cessation in patients with myocardial infarction]

The aim of this study was to evaluate the efficacy of an structured intervention based on a medical advice versus to the ordinary anti-tobacco advice in patients with miocardial infarction who are attended in an Intensive Care Unit (ICU).

90 patients were randomly selected to receive either the specific intervention (intervention group) or the ordinary advice (control group). The medical advice was given during the ICU hospitalization and during the second, the third and the fourth week. One year later the smoking habit was evaluated.

After one year 26 patients of the intervention group and 31 patients of the control group had stopped smoking (RR = 0.88 [CI 95% RR] 0.57 to 1.37).

The percentage of patients who stop smoking after a miocardial infarction is high. The structured medical counselling was not effective to reduce the number of smokers at one year.
