متن کاملAmbulatory norepinephrine treatment of severe autonomic orthostatic hypotension.
OBJECTIVES This study was designed to establish a patient-controlled, ambulatory norepinephrine treatment of refractory orthostatic hypotension due to primary autonomic failure. BACKGROUND Autonomic dysfunction leads to disabling postural hypotension. Particularly in primary autonomic dysfunction, repeated syncope and immobilization can be the result. Medical treatment of orthostatic hypotens...
متن کاملAssociation between supine hypertension and orthostatic hypotension in autonomic failure.
Supine hypertension occurs commonly in primary chronic autonomic failure. This study explored whether supine hypertension in this setting is associated with orthostatic hypotension (OH), and if so, what mechanisms might underlie this association. Supine and upright blood pressures, hemodynamic responses to the Valsalva maneuver, baroreflex-cardiovagal gain, and plasma norepinephrine (NE) levels...

Introduction Orthostatic hypotension is a relatively common symptom caused by a variety of aetiologies. The most common of these are: neuropathies due to systemic diseases such as diabetes, amyloidosis and porphyria; vaso-vagal attacks; hypovolaemia; ShyDrager syndrome (idiopathic orthostatic hypotension); adverse effects of anti-adrenergic drugs, L-dopa and dopaminergic drugs; phaeochromocytom...
