[Carbohydrate tolerance in patients with myocardial infarct according to prednisolone-glucose tolerance test].

Sensitivity to carbohydrates was studied in 100 patients in the subacute period of myocardial infarction by the prednisolne-glucose tolerance test with parallel determination of the content of sugar and pyruvic and lactic acids. Latent, predominantly mild disorders of carbohydrate metabolism were revealed in most patients. Considerably diminished glucose tolerance (diabetic-type sugar curve) was encountered in 12.5% of patients with normal and in 17.9% of those with excessive body weight. The prednisolone-glucose tolerance test and the tests for the content of pyruvic and lactic acids conducted in dynamics showed a statistically reliable increase in the pyruvate level on a fasting stomach and after glucose loads and of the lactate level on a fasting stomach and at the end of the examination. In diabetictype glycemic curves, however, the peak sugar levels were paralleled by normal content of pyruvic and lactic acids. The glycemia indices revealed in dynamics of the prednisolone-glucose tolerance test were significantly higher in patients with an increased blood sugar content in the acute period of myocardial infarction.
