Is Blood Pressure Really a Trigger for the Circadian Rhythm of Subarachnoid Hemorrhage?
Stroke 26:1805-1810, Kleinpeter,G.,et al, 1995
See this aricle in Pubmed
Article Abstract
The incidence of SAH conforms to circadian blood pressure variation in hypertensive patients,similar to the diurnal rhythms observed with strokes and myocardial infarctions.This leads to the hypothesis that blood pressure elevation is a trigger for the onset of bleeding in this group.In clear contrast,normotensive individuals with cerebrovascular aneurysms seem to have a random 24-hour distribution of SAH onset times,thus leaving the nature of a possible trigger mechanism unresolved.
