Pressor effects of norepinephrine after drastic reduction of sodium intake.
نویسنده
چکیده
The mechanisms wh(eeby, dietary sodium restriction leads to decreased arterial blood pressure is obscure. Previously reported studies of patients with arterial hypertension showed a lessened pressor response to norepinephrine after sodium restriction. In the present investigations, reduction in pressor response to norepinephrine during the low sodium period was observed only occasionally; sodium restriction decreases blood pressure in some hypertensive patients by other unknown mechanisms.

متن کاملEffect of moderate salt restriction and high potassium intake on pressor hormones, response to noradrenaline and baroreceptor function in man.
1. Twenty-one normotensive subjects were studied to assess any possible benefits of moderate salt restriction and of high potassium intake in the prevention of hypertension in man. 2. The effects of salt reduction from 200 to 50 mmol/day and/or of an increase of potassium intake from 80 to 200 mmol/day over a 2 week period, on blood pressure, plasma noradrenaline, adrenaline, vasopressin, renin...
متن کاملPressor reactivity to norepinephrine and angiotensin in salt-sensitive hypertensive patients.
The mechanisms responsible for increased blood pressure in response to a high dietary sodium intake in salt-sensitive patients with essential hypertension are only partially understood. The possibility that increased reactivity to pressor hormones might contribute to hypertension in these patients has not been adequately investigated. We studied 11 salt-sensitive and 15 salt-resistant patients ...
متن کاملMetoclopramide in the diagnosis of pheochromocytoma.
Cardiovascular and plasma catecholamine responses to metoclopramide (MCP), a dopamine antagonist, were examined in 5 patients with pheochromocytoma, 12 patients with essential hypertension (EHT) and 9 normotensive (NT) subjects who displayed symptoms suggestive of pheochromocytoma on a constant daily intake of 100 mEq sodium and 80 mEq potassium. Significant pressor responses to intravenous dos...
متن کاملSodium intake alters the effects of norepinephrine on blood pressure.
To examine the interactions between sodium balance and the sympathetic nervous system, we studied eight normotensive men after high (800 mEq/day) and low (10 mEq/day) sodium intake. We measured blood pressure (BP), arterial, venous, and urinary norepinephrine (NE) before and during incremental infusion of NE. We found significant direct, linear relationships (p less than 0.001) between the dose...
