Cerebral vasomotor reactivity in normotensive and spontaneously hypertensive rats.
Intravenously injected metaraminol induced a larger blood pressure increase in spontaneously hypertensive rats (SHR) than in normotensive controls (NR) when the pressure was raised from the same starting level. Cerebral blood flow (CBF) response in NR was either perfect autoregulation, partial autoregulation or "break-through." When present, the autoregulatory response was very rapid, i.e. the ...
متن کاملCerebral hypercapnia-induced vasomotor reactivity in migraine with and without aura: a case-control study
Abstract Background: Dysfunction of the autonomic nervous system has long been a subject of considerable debate and a large number of studies have disclosed contradictory results. The aim of this study was to compare cerebral vasomotor reactivity in migraine with aura (MWA) patients with migraine without aura (MWO) ones. Methods: Ten MWA patients (7 females and 3 males mean age: 39.70 years, S...
متن کاملPostexercise blood pressure reduction in elderly hypertensive patients.
OBJECTIVES We sought to study: 1) the impact of hemodynamic and left ventricular function on short-term postexercise blood pressure reduction in elderly hypertensive patients; and 2) the 22-h postexercise effects on ambulatory blood pressure in elderly hypertensive patients. BACKGROUND Although early exercise provokes postexercise blood pressure reduction, the mechanisms underlying this respo...
متن کاملTemporary reduction of blood pressure and sympathetic nerve activity in hypertensive patients after microvascular decompression.
BACKGROUND AND PURPOSE Experimental studies suggested neurovascular compression of the brain stem as a cause of hypertension. The aim of our prospective study was to investigate the effect of microvascular decompression in patients with severe hypertension with neurovascular compression on blood pressure and central sympathetic nerve activity in the long-term. METHODS Fourteen patients (4 mal...
