The onset of subarachnoid hemorrhage is significantly correlated with diurnal blood pressure variations, occurring more frequently during waking hours when blood pressure is higher.
No takes yet. Share an insight, caveat, or question.
Supports link between diurnal BP peaks and SAH onset; hypothesis-generating and should not change practice.
Fogelholm et al. (1995) studied this question.
