[Rehabilitation centers: for whom? Why and how long?].

The clinical profile of coronary patients admitted to cardiac rehabilitation centres after myocardial infarction has changed considerably in the last 15 years. Complementary investigations (coronary angiography, studies of left ventricular function) provide accurate information which improves the process of rehabilitation. Global management of the coronary patient requires and justifies, especially in young adults, taking into consideration the physical, psychological and socio-professional consequences of a myocardial infarction. The indications of rehabilitation are much more comprehensive nowadays. Even patients with significant haemodynamic impairment can benefit from a stay in a specialised centre. Contraindications are usually only temporary. Finally, an enquiry performed in 33 French cardiac rehabilitation centres shows large variations in methods, personnel and organisation. However, as a general rule, a 3 week stay seems to be adequate but it is logical to continue rehabilitation when the patients goes home to pursue and maintain at long term the results obtained on discharge from a specialised centre.
