Deviation of plasmatic aldosterone and significance of the stimulating (ACTH-cortrosyn) and inhibitory (propranolol) effects in hypertension and cardiovascular pathology.

Starting from the interference between the renin-angiotensin-aldosterone (RAA) system and cardiovascular pathology in arterial hypertension (AH) we have made a correlative study of the cardiovascular system and plasmatic aldosterone in normal and hypertensive subjects under conditions of stimulation (ACTH) and inhibition (propranolol). After administration of ACTH (one of the physiologic mediators of stress) increased values for plasmatic aldosterone were found. Negative cardiovascular effect: arrhthmia, angor, AH, cardiac asthma, under the condition of preexisting cardiovascular pathology or altered steroidogensis, were also noticed.
