Plasma norepinephrine in stroke.
Cardiac arrhythmias, myocardial necrosis and ECG abnormalities in stroke may result from abnormally high levels of sympathetic activity. To examine this possibility, plasma norepinephrine, epinephrine and dopamine were measured in 74 patients with cerebral infarction, 18 with transient ischemic attacks and 33 non-stroke controls. Mean norepinephrine, epinephrine and dopamine values (pg/ml) in c...
متن کاملPlasma 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 cortisol and norepinephrine in Alzheimer's disease: opposite relations with recall performance and stage of progression.
OBJECTIVE Alzheimer's disease (AD) is characterized by effortful retrieval memory impairments, loss of hippocampal neurons and elevated plasma cortisol (CORT) concentrations. The latter could induce further memory decline. AD is also characterized by increased central and peripheral noradrenergic activity. Since noradrenergic function is involved in memory formation, this upregulated function c...
متن کاملPlasma norepinephrine variations with dietary sodium intake.
Plasma catecholamine and renin activity levels were measured across a range of dietary sodium intakes (10--300 mEq/day) in 20 normal male volunteers. Supine plasma norepinephrine levels presented a triphasic pattern in relation to urine sodium, whereas epinephrine levels were not significantly altered by sodium intake, and renin showed the well-known hyperbolic relationship to urine sodium excr...
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...
