[Diabetics in secondary prevention].

It is well known that diabetics live with a significantly higher incidence of a cardiac insufficiency and that acute ischemia is the main cause of death in this group (75%). The risk of suffering a myocardial infarction after ischemic incidences is significantly higher for diabetics than for patients with normal carbohydrate metabolism. Diabetes mellitus is not only responsible for acute incidences, but also for a higher incidence of chronic coronary diseases. Furthermore a disturbed tolerance glucose value was detected in studies for two-thirds of the patients which could even be proven after complete rehabilitation. It has also been shown that the severity of hyperglycemia is in a close inverse relationship to the volume of the brain tissue which can be saved. For this reason hyperglycemia is possibly a therapeutic aim in case of acute ischemic incidences. Therefore the adjustment of blood sugar should be the primary aim to reduce risk in any cases of vascular incidences.
