BACKGROUND: Coronary disease is the major worldwide cause of death, according to the World Health Organization (WHO) and the second in Brazil. Sudden death occurs 4 to 6 times more frequently in those who have suffered an acute myocardial infarction (AMI); within 6 years, 18% of the men and 35% of the women will have a new AMI. The secondary prevention, of which effectiveness has been previously demonstrated, is of utmost importance. OBJECTIVE: To test the effectiveness of a multiprofessional program that aims at modifying risk factors for atherosclerosis in the public health system. METHODS: Of the 2,337 patients with coronary artery disease undergoing outpatient treatment, 513 with a coronary angiography study agreed to participate in the present study, which used lectures on how and why to control risk factors as therapeutic tool. Statistical analysis: significant variation pre and post-intervention; paired Student’s t test or Wilcoxon’s test ; existence of a significant difference between the two groups; Student’s t test for independent samples or Mann-Whitney test. Comparison among three groups: analysis of variance (ANOVA) or Kruskal-Wallis. RESULTS: Cholesterol, LDL, triglycerides, body mass index, Castelli indexes I and II and waist circumference showed a significant decrease, even in patients without hypolipemiant treatment. The assessment of the diet impact showed that 72% of the patients that did not follow a diet, started to do so. Physical activity: of the 55% sedentary patients, 71% started to exercise three or more times a week. Smoking: of the smokers, 60% (9% of the total) stopped smoking and 32% decreased the number of cigarettes. CONCLUSION: These results demonstrated the effectiveness of the programs to improve life habits when applied to the units of the public health system.
