Blood pressure variability and urine flow in the conscious dog.
Pressure-dependent urine production is considered to be a major factor in long-term blood pressure control. The phenomenon has been well characterized for fixed levels of renal perfusion pressure (RPP), but the influence of physiological fluctuations in RPP and spontaneous variations in renal blood flow (RBF) on short-term urine flow (UV) remain unclear. To clarify this issue, we studied the in...
متن کاملSodium excretion and blood pressure.
The urinary excretion of sodium, potassium, and water during three 24-hour periods were related to blood pressure in a sample of 49-year-old men. Of 3205 49-year-old men liring in Goteborg, 2376 (74%) took part in the blood pressure screening, and, of these, 120 subjects having blood pressures from the lowest to the highest were selected by systematic sampling based on diastolic blood pressure....
متن کاملElectrolyte and Water Excretion
The increased capacity of hypertensive subjects to excrete sodium is frequently reduced by effective antihypertensive drug treatment. This reduction in sodium excretion is not necessarily associated with changes in renal hemodynamic function or resting sodium excretion. It appears to result from an alteration in renal tubular activity. The findings suggest that the arterial pressure per se may ...
متن کاملThe relationship between sodium excretion and blood pressure, urine albumin, central retinal arteriolar equivalent
BACKGROUND Many studies showed an association between dietary salt intake, blood pressure and increased CVD risk. The potential reason may be related to vascular structural and functional changes, through alterations in endothelial function. The central retinal arteriolar equivalent and urinary albumin reflected vascular endothelial dysfunction in different part of the body. The urinary sodium-...
متن کاملStroke and blood pressure variability.
Sleep apnoea is associated with increased cardiovascular risk. Sleep apnoea is common after stroke and associated with increased blood pressure variability as described by Turkington and co-workers in this issue of Clinical Science. Both sleep apnoea and blood pressure variability confer a poor prognosis after stroke and are potentially treatable. Many studies of CPAP (continuous positive airwa...
