Abstract 2691: Multicenter, International Study of Stroke in the Young (MISSY): Initial Results on Racial Disparities in Early Outcomes

Background&Purpose: Strokes in young adults differ from cerebrovascular events in the general population due to a wider variety of etiopathogenic mechanisms as well as by incidence and outcomes. Limited data exist regarding racial disparities in stroke outcomes in this specific age subgroup. We sought to prospectively evaluate potential racial disparities in early outcomes of young individuals with stroke in a multicenter, international study. Subjects&Methods: We prospectively evaluated consecutive first-ever stroke patients aged 18-45 years old who were admitted in 7 tertiary care stroke centers in North America (n=2), Europe (n=3) and Asia (n=2) over a four-year period (2008-2011). Demographics, vascular risk factors, etiopathogenic mechanism of stroke and stroke severity at hospital admission (assessed using the NIHSS-score) were documented. Early functional outcome at 1 month following stroke onset was evaluated using modified Rankin Scale (mRS) score. Results: A total of 826 young adults (mean age 3...
