[Vasopressin content of the blood in ischemic heart disease patients and its interrelation with other hormones].

Blood vasopressin, tri-iodothyronine, total thyroxine, thyrotrophic hormone, cortisol, ACTH and insulin levels were measured in 60 chronic coronary patients aged 35 to 70. Coronary patients showed elevated blood vasopressin, particularly in the presence of frequently recurring anginal attacks. There was no significant difference in vasopressin levels of patients with and without attendant essential hypertension, those with atherosclerotic and postinfarction cardiosclerosis, or in relation to body weight. Insulin, cortisol, adrenocorticotrophic and thyrotrophic hormones were significantly increased, and tri-iodothyronine and total thyroxine, significantly decreased, in coronary patients as compared to the controls.
