Key result
The presence of suprasellar or intraventricular blood in subarachnoid hemorrhage was associated with higher initial plasma atrial natriuretic factor concentrations (131 vs 54 and 137 vs 84 pg/ml).

Is the presence of suprasellar or intraventricular blood associated with elevated plasma atrial natriuretic factor in patients with subarachnoid hemorrhage?
Suprasellar and intraventricular blood following subarachnoid hemorrhage are associated with elevated plasma atrial natriuretic factor concentrations, suggesting hypothalamic disturbance.
Diringer et al. (1991) conducted an observational in subarachnoid hemorrhage (n=26). Suprasellar or intraventricular blood vs. Absence of suprasellar or intraventricular blood was evaluated on Plasma atrial natriuretic factor concentration. The presence of suprasellar or intraventricular blood in subarachnoid hemorrhage was associated with higher initial plasma atrial natriuretic factor concentrations (131 vs 54 and 137 vs 84 pg/ml).
