[Education of patients with arterial disease. A plan for the use of Expert System in angiology via Minitel].

We are presenting a computer program requiring the use of an Expert System accessible by Minitel, intended for patients with arterial disease and their attending physician. The objective is not to make a diagnosis, but to train the patients in applying health measures to the handling and prevention of his/her disease. While remaining anonymous, the patient may consult the program at home, without any time constraint.
