Impact of Onset-to-Reperfusion Time on Stroke Mortality
Circulation: May 14, 2013
Background—Onset-to-reperfusion time has been reported to be associated with clinical prognosis. However, its impact on mortality remained to be assessed. Using a collaborative pooled analysis, we examined whether early mortality after successful endovascular treatment is time dependent.
Methods and Results—In a collaborative pooled analysis of 7 endovascular databases, we assessed the impact of onset-to-reperfusion time in large-artery occlusion (internal carotid artery or middle cerebral artery) on outcomes. Successful reperfusion was defined as complete or partial restoration of blood flow within 8 hours from symptom onset. Primary outcome was 90-day all-cause mortality. Read more
