Circadian variation in ischemic stroke subtypes.
BACKGROUND AND PURPOSE While previous studies suggest that the peak time period for the occurrence of ischemic stroke is in the mid- to late-morning hours, detailed information pertaining to circadian variations among the various stroke subtypes has been limited. The purpose of our study was to define the circadian patterns of symptom onset in an acute stroke trial with an established system fo...
متن کاملCircadian variation in acute ischemic stroke: a hospital-based study.
BACKGROUND AND PURPOSE We investigated circadian rhythm in ischemic stroke onset and its subtypes, differentiating between first-ever stroke and recurrent stroke. METHODS A consecutive series of 1223 patients with ischemic stroke was admitted at 2 reference hospitals; the time of onset of symptoms was obtained, differentiating between onset while asleep and awake. We compared circadian rhythm...
متن کاملCircadian variation in the frequency of ischemic stroke.
The frequency of myocardial infarction and sudden death is increased between 6 AM and noon. To determine whether the same is true for the onset of ischemic stroke, we studied 426 consecutive patients within 12 hours after the onset of their first hemispheric stroke. The frequency of onset of hemispheric stroke was significantly (p = 0.0001) higher from 6:01 AM to noon (56.1%) than from 12:01 PM...
متن کاملRetinopathy in ischemic stroke subtypes.
BACKGROUND AND PURPOSE Lacunar stroke is associated with an intrinsic cerebral small vessel disorder of unknown etiology, although possible causes include increased blood-brain barrier permeability. Retinal arterioles are similar to cerebral small vessels and retinopathy occurs secondary to increased blood-retinal barrier permeability. We hypothesized that there would be higher rates of retinop...
