Retrospecting atrial fibrillation and stroke severity: impact onset time of acute ischemic stroke

Abstract

Irrespective of the duration of the therapeutic window, the prognosis for acute ischemic stroke is closely correlated with the time of treatment initiation. Time from symptom onset to hospital arrival, defined as the onset time, is the determining parameter. Besides the prehospital transport, whether relative factors of illness may have an impact on stroke onset time is uncertain, which were invested in this study through statistical analyses. Results show that relative factors of illness, such as history of atrial fibrillation and stroke severity, impact stroke onset time.
