since the report from the national high blood pressure (bp) education program working group on bp in children and adolescents and the introduction of a new description called prehypertension many data have been provided on its rate of progression to hypertension, its prevalence and association with other cardiovascular (cv) risk factors and its therapy. making a diagnosis of prehypertension in ...

background: essential hypertension tends to a familial mode. its pattern of inheritance is heterogeneous, but the frequencies of different mode of inheritance vary in different populations. determining of the mode of inheritance in each family is the basic information that is needed for the risk estimation in those family members. determination of pattern of inheritance in families with at leas...

There has been increasing interest in the normal blood pressures of isolated and unsophisticated communities in the last few years. In particular, several investigators have questioned whether the rise in blood pressure with increasing age which appears to be common to all "Western" peoples is universal for mankind, and they have suggested that this rise is due to the occurrence among Westerner...

Attached to this letter, please find an insolation sensitivity study of the HI-STORM EHT thermal model for PFS. We trust that the above information fulfills the verbal commitment made by us in an earlier telecon.

Previous studies from this laboratory (1-4) have shown that: 1) there is a statistically significant increase in the mean urinary aldosterone excretion from groups of patients with essential, renal or malignant hypertension, as compared with that of normal subjects similarly studied; 2) 43 per cent of patients with essential hypertension have urinary aldosterone values above normal limits; 3) t...

In 16 of 28 patients with benign essential hypertension, reduction of mean arterial pressure to 75 to 120 mm Hg by infusion of sodium nitroprusside caused significant increase in renin release estimated by the renal-systemic difference of renin activity and renal plasma flow (RPF). The threshold at which renin release increased was shifted to a range that was intermediate between that previousl...

Aldosterone secretion rate, metabolic clearance rate, and/or plasma concentration were determined in 16 patients with benign, uncomplicated essential hypertension and compared with those of control subjects. The mean metabolic clearance rate of aldosterone in 10 patients was significantly (P < 0.001) lower (mean 867 liters of plasma/day per m(2) +/-270 SD) than in a group of 7 healthy subjects ...
