[Change in secretion of somatotropic hormone and insulin in myocardial infarct]

Twenty patients with myocardial infarction and 10 normal individuals were subjected to a carbohydrates tolerance test, and their secretion of insulin and somatotrophic hormone in response to intravenous injections of glucose was studied. The blood serum concentration of insulin and of somatotrophic hormone was determined by way of radio-immuno-assay, while the blood sugar concentration -- by the orthotoluidine technique. It is established that myocardial infarction, like other stress states, is accompanied by disorders in the function of the hypophysis and the adrenal glands, which, in turn, is accompanied by disorders in the secretion of insulin and of somatotrophic hormone.
