Circadian Variation in Ischemic Stroke Subtypes Stroke 30:1793-1795, Chaturvedi,S.,et al, 1999 See this aricle in Pubmed Article Abstract The greatest portion of atherothrombotic strokes (25.7%), cardioembolic strokes (30.5%), and strokes of other/unknown mechanism (27.1%) occurred between 6:01 AM and 12:00 noon. The greatest portion of lacunar strokes (31.6%) were present on awakening. More than one half of the infarcts in this series were either present on awakening or occurred in mid- to late-morning hours. The correlation between stroke subtype and time of symptom onset did not reach statistical significance (P=0.07, Pearson's x^2 method). Although there is a trend for clustering of ischemic stroke in the morning hours, there is insufficient specificity to predict with any reasonable likelihood the stroke subtype according to the circadian pattern of symptom onset.
