I1-imidazoline agonist moxonidine decreases sympathetic nerve activity and blood pressure in hypertensives.

Moxonidine is an I1-imidazoline receptor agonist that reduces blood pressure in hypertensives. Experimental data suggest that moxonidine inhibits central sympathetic activity. However, whether such a mechanism is involved in vivo in humans is still unclear. We investigated the effects of 0.4 mg moxonidine orally on muscle sympathetic nerve activity and heart rate in an open study in 8 healthy v...

Sympathetic activity and the heterogenous blood pressure response to exercise training in hypertensives.

To test whether changes in sympathetic nervous system (SNS) activity or insulin sensitivity contribute to the heterogeneous blood pressure response to aerobic exercise training, we used compartmental analysis of [3H]norepinephrine kinetics to determine the extravascular norepinephrine release rate (NE2) as an index of systemic SNS activity and determined the insulin sensitivity index (S(I)) by ...

Chronic I(1)-imidazoline agonism : sympathetic mechanisms in hypertension.

Evidence exists for a state of sympathetic hyperactivity in essential hypertension, and moxonidine, a new central sympathetic inhibitor, has been introduced for its treatment. Acute administration of moxonidine lowers peripheral sympathetic neural output. This study examined the effect of chronic moxonidine therapy, at increasing therapeutic doses, on resting peripheral sympathetic activity and...

Chronic Deep Brain Stimulation Decreases Blood Pressure and Sympathetic Nerve Activity in a Drug- and Device-Resistant Hypertensive Patient.

We were approached by a 54-year-old female patient wishing to receive deep brain stimulation (DBS), a procedure that we previously discovered to normalize blood pressure (BP) in a drug-resistant hypertensive patient, to treat her severe, refractory hypertension. On her first visit to the specialist Hypertension Clinic (Bristol Heart Institute, University Hospitals Bristol NHS Foundation Trust) ...

Decreases in blood pressure and sympathetic nerve activity by microvascular decompression of the rostral ventrolateral medulla in essential hypertension.

BACKGROUND Neurovascular compression of the rostral ventrolateral medulla, a major center regulating sympathetic nerve activity, may be causally related to essential hypertension. Microvascular decompression of the rostral ventrolateral medulla decreases elevated blood pressure. CASE DESCRIPTION A 47-year-old male essential hypertension patient with hemifacial nerve spasms exhibited neurovasc...
