Borderline hypertension: relationship between age, hemodynamics and circulating catecholamines.
The relationships between age, systemic and renal hemodynamics, circulating catecholamines (norepinephrine, epinephrine and dopamine) and intravascular volumes were studied in 38 normotensive subjects and in 77 patients with borderline essential hypertension. Borderline hypertensive patients had a higher cardiac index (p less than 0.02) and renal blood flow (p less than 0.05) than normotensive ...
متن کاملHemodynamic studies in patients with borderline blood pressure elevation.
Ninety-four patients with occasionally elevated (borderline) blood pressure, 61 patients with asymptomatic established hypertension, and 63 normal subjects have been studied at rest and during a progressive exercise test on a cycle ergometer. Subjects with borderline blood pressure had increased cardiac output in the resting recumbent position, but this was not maintained in the sitting positio...
متن کاملInteraction between renin and the autonomic nervous system in hypertension.
The abnormal distribution of plasma renin values described in established essential hypertension are also found in patients with very early, borderline hypertension. In established hypertension, renin values have been used to draw inferences about the pathophysiology of blood pressure elevation. Within this concept, the low-renin state is considered a volume-dependent (volume expanded) form of ...
متن کاملHemodynamic responses to tilt and beta-adrenergic blockade in young patients with borderline hypertension.
SUMMARY Seventeen young patients with b9rderline hypertension (one female) and 18 normo-tensive paid volunteers (two females) were studied at rest and in the tilted position after 10 min of 450 head-up tilt. Cardiac output, heart rate, and intra-arterial pressure were recorded. The measurements at rest and during the tilt were repeated after beta-adrenergic blockade with propranolol. By compari...
متن کاملAutonomic 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...
