Abstract:
Plasma levels of immunoreactive atrial natriuretic factor (IR-ANF) were evaluated by radioimmunoassay in several models of experimental hypertension and in human hypertension. Plasma levels of IR-ANF are consistently increased in all models of experimental hypertension studied so far. This is accompanied by a decrease of IR-ANF levels in the left atrium at certain times. Plasma levels of IR-ANF are not increased in human essential hypertension, except in the severe form (diastolic blood pressure above 110 mmHg). Peripheral levels of IR-ANF in renovascular hypertension do not differ from normal but are increased above normal in aortic blood.

Epinephrine and Norepinephrine
The adrenal medulla releases epinephrine and norepinephrine, catecholamines that enhance and extend the sympathetic or "fight or flight" physiological response. These hormones escalate heart rate and the force of contraction while...
