Hyperinsulinemia, family history of hypertension, and essential hypertension.
The aim of this study was the evaluation of the relationships among hyperinsulinemia, a family history of hypertension, and essential hypertension. Insulin and C-peptide responses to an oral glucose load were studied in 175 lean normotensives (N) and untreated hypertensives (H) with (F+) and without (F-) a family history of hypertension: 30 NF-, 30 NF+, 45 HF-, and 70 HF+. The groups were compa...
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 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 کاملPressor Substances in Arterial Hypertension
Some pharmacological and chemical qualities of pherentasin, a vasoconstrictor substance procured from human hypertensive blood, were studied by a new assay method using the spirally cut rabbit aorta. Of a number of drugs tested, six metal-binding agents including hydralazine inactivated the active principle. The material was stable in acid but not in alkali. It was destroyed by drying. Chemical...
متن کاملPressor Substances in Arterial Hypertension
Pherentasin is the only pressor substance found in blood of hypertensive patients which is not found in normal blood. This study defines its unit and compares its concentration with diastolic blood pressure level, type of hypertension, and age of patients. Lack of correlation between blood pressure level and pherentasin content suggests considerable variation in the amount of depressor substanc...
