Abstract
Background and Purpose Few studies have investigated the relationship between the specific functional factors potentially associated with functional level and stroke recurrence. We conducted a study of patients with noncardioembolic ischemic stroke (NCIS) to determine the functional factors affecting recurrence within the first year. Methods In total, 568 first-ever NCIS patients (age=65.1 +/- 17.4 years, mean +/- SD) were analyzed in a multicenter, prospective cohort study registered from August 2012. Demographic characteristics, past medical history, comorbidities, laboratory data, stroke features in neuroimaging, acute treatments, and medications at discharge were assessed. Functional factors reflecting gross functional impairment, ambulatory function, motor function, activities of daily living, cognition, language ability, swallowing function, mood, and quality of life were comprehensively evaluated in face-to-face assessments using standardized tools at the time of discharge. Results The cumulative incidence of stroke recurrence in NCIS was 6.0% (n=34) at 1 year. The period from admission to discharge was 34.4 +/- 7.0 days. The independent predictors of stroke recurrence within 1 year in multivariate Cox proportional-hazards regression analyses were 1) age [per-year hazard ratio (HR)=1.04, 95% confidence interval (CI)=0.97-1.06, p=0.048], 2) Charlson Comorbidity Index higher than 2 (HR=1.72, 95% CI=1.26-2.22, p= 0.016), 3) modified Rankin Scale score of 3 or more at discharge (HR=1.56, 95% CI=1.22-1.94, p=0.032), and 4) Functional Ambulation Category of 3 or less at discharge (HR=2.56, 95% CI= 1.84-3.31, p=0.008). Conclusions In addition to patient age, moderate-to-severe functional impairment requiring the help of others (especially for ambulation) at the time of discharge and the severity of comorbidity were independent predictors of stroke recurrence within 1 year of the first NCIS.
