Poststroke Outcomes Vary by Pathogenic Stroke Subtype in The Atherosclerosis Risk in Communities Study

STROKEAHA: May 16, 2013

Background and Purpose—Early risk of recurrence and mortality after stroke differs by subtype, but less is known about long-term recurrence and hospital readmissions. These differences have economic implications and will affect long-term disability and stroke survivor quality of life. We examined recurrent stroke, all-cause hospital readmission, and mortality by index pathogenic subtype.

Methods—We identified 987 Atherosclerosis Risk in Communities Study cohort participants with first-ever stroke and followed them for a median 5.3 years after first stroke. Outcomes were compared across index subtypes (infarction: thrombotic, cardioembolic, and lacunar; hemorrhagic: subarachnoid and intracerebral) using Kaplan–Meier analysis and Cox proportional hazards regression, adjusting for age, sex, and race. Read more
