Neurovascular compression: sympathetic activity in severe arterial hypertension.
Compression of the rostral ventrolateral medulla oblongata (RVLM) by an abnormally located artery is regarded as one possible cause of arterial hypertension. There exists a limited set of data suggesting that increased sympathetic activity in patients with RVLM compression may lead to arterial hypertension. Accordingly, we decided to assess the sympathetic activity in patients with severe arter...
متن کاملHypertension in patients with neurovascular compression is associated with increased central sympathetic outflow.
Recent data suggest a causal relationship between essential hypertension and neurovascular compression (NVC) at the rostral ventrolateral medulla. An increase of central sympathetic outflow might be an underlying pathomechanism. The sympathetic nerve activity to muscle was recorded in 21 patients with hypertension with NVC (NVC+ group) and in 12 patients with hypertension without NVC (NVC- grou...
متن کاملRelationship of neurovascular compression to central sympathetic discharge and essential hypertension.
OBJECTIVES We planned to examine the relationship between neurovascular compression (NVC) of the rostral ventrolateral medulla (RVLM) and the magnitude of central sympathetic hyperactivity in normal subjects and in patients with untreated and uncomplicated essential hypertension (EHT). BACKGROUND Previously it has not been possible to establish a definitive relationship between EHT and NVC of...
متن کاملIncreased sympathetic nerve activity correlates with neurovascular compression at the rostral ventrolateral medulla.
We used microneurography to measure muscle sympathetic nerve activity (MSNA) in 25 hypertensive subjects and correlated these results with the presence or absence of signs of neurovascular compression (NVC) at the rostral ventrolateral (RVL) medulla on MRI. Subjects were divided into 3 groups based on MRI findings: NVC-, no MRI evidence of NVC (N=9); NVC+contact, image showing artery in contact...
متن کاملNeural sympathetic activity in essential hypertension.
Neural Sympathetic Activity in Essential Hypertension To the Editor: We read with great interest the article by Schlaich et al1 dealing with the issue of sympathetic augmentation in hypertension. In 1993, we demonstrated that neural sympathetic activity predominance is registered in essential hypertensive patients.2 These findings were supported by the overwhelming circulating noradrenaline (NA...
