Night Time Versus Daytime Transient Ischaemic Attack and Ischaemic Stroke:QA Prospective Study of 110 Patients JNNP 67:463-467, Bassetti,C.&Aldrich,M., 1999 See this aricle in Pubmed Article Abstract A night time onset of transient ischaemic attack or stroke was reported by 23 (21%) of 110 patients. Patients with daytime and night time events were similar in demographics; risk factors; associated vascular diseases; clinical and polys omnographic sleep characteristics (including severity of sleep apnoea); and stroke severity, aetiology, and outcome. Only the diastolic blood pressure at admission was significantly lower in patients with night time evens (74 v 82 mm Hg, p=0.01). Patien ts with night time and daytime transient ischaemic attack/stroke are similar in sleep and stroke characteristics. Diastolic hypotension may predispose to night time cerebrovascular events. Factors not assessed in this study probably account for the circ adian variation in the frequency of transient ischaemic attack and acute ischaemic stroke.
