Myocardial infarction is a frequent, serious and recurrent complication of a chronic disease: atherosclerosis. Therapeutic advances have improved the clinical outcome of affected patients and have shortened the hospital length of stay. However, to decrease the recurrence of cardiovascular events, it is essential to increase adherence to therapeutic projects by improving information given to coronary patients during the short initial hospitalization. This can be achieved by using tools that have been developed for the management of chronic disease: therapeutic education and motivational interviews. Moreover, these information tools have to perform well and have to be used at appropriate times to ensure a positive effect on patients.
