Autonomic nervous cardiovascular regulation in borderline hypertension.
Borderline hypertension attracts investigative interest since it is an early predictor of established hypertension and its sequelae. This condition offers the opportunity of studying arterial hypertension at its inception, before the development of secondary pressure-related changes. A number of abnormalities of the circulation have been described in borderline hypertension. The peripheral resi...
متن کاملProstaglandins contribute to cardiovascular reflexes evoked by static muscular contraction.
The purpose of this study was to determine the contribution of prostaglandins to the reflex cardiovascular responses induced by static contraction of the hind limb in cats, i.e., the exercise reflex. To accomplish this, the cardiovascular responses to hind limb contraction induced by electrical stimulation of spinal cord ventral roots L6-7 and S1 were compared before and after inhibition of pro...
متن کاملPressor factors and cardiovascular pressor responsiveness in borderline hypertension.
The role of various pressor factors and cardiovascular responsiveness to norepinephrine or angiotensin II in the pathogenesis of borderline hypertension was evaluated. Exchangeable body sodium, blood volume, plasma renin activity, norepinephrine or dopamine levels, and norepinephrine or epinephrine excretion rates were similar between 24 patients with borderline hypertension (mean age 34 +/- 4 ...
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...
متن کاملAntibodies to endothelial cells in borderline hypertension.
BACKGROUND Antibodies to endothelial cells (aECs) and to cardiolipin (aCLs) are implicated in autoimmune diseases like systemic lupus erythematosus vasculitis. Beta2-Glycoprotein 1 (beta2GP1) is a cofactor for aCLs. The present study investigated the possible role of aECs, aCLs, and abeta2GP1 in borderline hypertension. METHODS AND RESULTS Seventy-three men with borderline hypertension (BHT) ...
