[Relations between insulin, somatotropic hormone and somatostatin secretions in patients with ischemic heart disease].
Secretions of hormones responsible for carbohydrate metabolism, STH, insulin, S-peptide and somatostatin, were measured in coronary patients in order to investigate hormonal mechanisms involved in disordered carbohydrate metabolism. A persistent hyperinsulinemia was found in patients with disordered carbohydrate metabolism, both in cases of glucose stimulation and insulin inhibition, where glandular function was assessed on the basis of S-peptide concentration as opposed to the control level. Baseline somatostatin concentrations were beyond the method's sensitivity limit in most of the patients. There was a tendency to elevated hormonal levels in the insulin test, whereas glucose administration produced an opposite response. Blood basal STH levels did not differ significantly in the study groups, however the increase in hormonal secretion following insulin administration was less pronounced in patients with disordered carbohydrate metabolism as compared to other groups.
