Plasma Norepinephrine in Essential Hypertension
Of 32 studies comparing plasma norepinephrine concentrations in hypertensive and normotensive groups, 28 (88%) reported higher levels in the hypertensive group. However, only 13 (41%) of the studies reported statistically significant hypertensive-nonnotensive differences in norepinephrine, leading the present attempt to identify factors differentiating "positive" studies (those reporting signif...
متن کاملPlasma norepinephrine during stress in essential hypertension.
Comparative studies of plasma norepinephrine in patients with essential hypertension and in normotensive controls have consistently reported higher mean resting levels of norepinephrine in the hypertensive groups, but the hypertensive-normotensive differences have often been small and, in about three-fifths of the studies, not statistically significant. The author reviewed the medical literatur...
متن کاملPlasma norepinephrine response to tilting in essential hypertension.
A significant increase in the plasma concentration of norepinephrine on tilting 19 normal st:bjects from the horizontal to 600 upright is described. Evidence that this represents an increased neuj-oadrenergic activity to maintain cerebral circulation despite the periph-e-pooling of blood has previously been reported. When 9 subjects with severe essen-LI il hypertension were similarly tilted, th...
متن کاملPlasma l-[3H]norepinephrine, d-[14C]norepinephrine, and d,l-[3H]isoproterenol kinetics in essential hypertension.
We infused tracer-labeled l-[3H]-norepinephrine, d-[14C]norepinephrine, and d,l-[3H]-isoproterenol simultaneously into patients with essential hypertension and into normotensive control subjects, in order to determine whether abnormalities in the disappearance kinetics of these substances characterized the hypertensive patients. The mean preinfusion venous plasma norepinephrine concentration wa...
متن کاملPlasma norepinephrine and age as determinants of systemic hemodynamics in men with established essential hypertension.
Two primary predictor variables, age and supine plasma norepinephrine, were studied with respect to their influences on supine hemodynamic variables in 52 white men with essential hypertension who were 23 to 67 years of age and had been off active therapy for at least 4 weeks. Plasma norepinephrine was related to age (r = 0.39, p less than 0.01), correlated closely with mean arterial pressure (...
