Pressor response to norepinephrine in essential hypertension. A study in families.
Study of pressor response to graded, increased doses of infused norepinephrine in patients with essential hypertension, their normotensive siblings, and normotensive control subjects unrelated to the patients and without a family history of hypertension indicated an increased response in the two former groups. Comparison of the dose-response curves in the three groups showed that the difference...
متن کاملarAdrenergic Blockade and Cardiovascular Pressor Responses in Essential Hypertension
The effects of selective a,-adrenergic blockade with terazosin on blood pressure and cardiovascular pressor responsiveness were assessed in 17 subjects with mild to moderate essential hypertension (mean age, 48 ± 2 [SEM] years). As compared with a 2-week placebo period, 8 weeks of terazosin treatment (mean dose, 10.5 ± 1.7 mg/day) caused a fall of supine (from 153/103 ± 3/2 to 143/96 ± 4/2 mm H...
متن کاملDopaminergic modulation of pressor and hormonal responses in essential hypertension.
Hormonal and mean arterial pressure (MAP) responses to posture, isometric handgrip, angiotensin II (AII), adrenocorticotrophic hormone (ACTH), and metoclopramide (MCP), a dopamine (DA) antagonist, were examined in nine men with essential hypertension and nine age- and weight-matched normotensive men on a constant 100 mEq sodium and 80 mEq potassium intake before and after 4 days of administrati...
متن کاملThe pressor response to angiotensin II in patients with low renin essential hypertension.
The etiology of low renin essential hypertension (LREH) has not been established with certainty, but mineralocorticoid excess has been implicated frequently in its pathogenesis. The finding of several investigators of a normal exchangeable sodium space and extracellular fluid volume, however, does not support this hypothesis. To evaluate the possible role of sodium and water retention in LREH, ...
متن کاملArterial response during cold pressor test in borderline hypertension.
We observed previously that sympathetic activation produced by lower body negative pressure increases pulse-pressure amplification with little change in mean pressure. Whether the cold pressor test (CPT) might produce a similar hemodynamic pattern has been ignored. Ten subjects with borderline hypertension and ten age- and sex-matched normotensive controls were compared to investigate carotid-b...
