Plasma atrial natriuretic factor and subarachnoid hemorrhage.
Hyponatremia is common following aneurysmal subarachnoid hemorrhage and has been linked to the syndrome of inappropriate secretion of antidiuretic hormone. However, the demonstration of volume depletion and natriuresis in some patients has suggested that salt wasting is a more likely etiology. Atrial natriuretic factor appears to play a role in both central and peripheral regulation of sodium h...
متن کاملAtrial natriuretic factor and salt wasting after aneurysmal subarachnoid hemorrhage.
BACKGROUND AND PURPOSE The causes of volume depletion and hyponatremia after subarachnoid hemorrhage are not fully understood but may be in part due to natriuresis or "cerebral salt wasting." Because previous studies using infrequent hormone sampling have given inconsistent results, we determined if elevations in atrial natriuretic factor concentrations preceded negative sodium and fluid balanc...
متن کاملSuprasellar and intraventricular blood predict elevated plasma atrial natriuretic factor in subarachnoid hemorrhage.
Following subarachnoid hemorrhage, the plasma concentration of atrial natriuretic factor is elevated and appears to be independent of atrial stretch. While the hypothalamus and circumventricular organs contribute to sodium and intravascular volume regulation, their influence on atrial natriuretic factor is not known. We tested the hypothesis that, following subarachnoid hemorrhage, suprasellar ...
متن کاملPlasma atrial natriuretic factor concentrations in essential and renovascular hypertension.
Plasma atrial natriuretic factor concentrations were measured in 44 patients with mild untreated essential hypertension and 48 normotensive controls. Mean venous plasma atrial natriuretic factor concentrations were 13.2 (SEM 1.5) and 13.0 (1.3) ng/l in the hypertensive patients and controls, respectively. Plasma atrial natriuretic factor concentrations were significantly correlated with age in ...
متن کاملPlasma Atrial Natriuretic Factor and Cyclic GMP in Mitral Stenosis
To study the relation between plasma atrial natriuretic factor (ANF) and cardiac pressures, we measured plasma ANF in 24 patients with mitral stenosis 30 minutes before and 20 minutes after balloon mitral valvulotomy. All patients were without physical signs of congestive heart failure. Normal sinus rhythm was present in 15 (group 1), whereas the other nine (group 2) had permanent atrial fibril...
