Stress Response and Antihypertensive Treatment

Results from many studies suggest that the central nervous system may play an important role in enhancing and maintaining sympathetic, metabolic and haemodynamic effects in patients with hypertension. Likewise, emotional and mental stresses may provoke phasic and sustained adrenergic responses in normotensive and untreated hypertensive patients. Because the various antihypertensive medications have different mechanisms of action, and elicit different neurovegetative responses, it is useful to distinguish between the effects of different treatments on sympathetic activity.
