Abstract

Background: Rate of ischemic strokes and transient ischemic attacks (TIAs) increases with age. There is lack of evidence on how age affects treatment strategies and outcomes. Our aim is to compare epidemiology of ischemic strokes and TIAs in adult and geriatric populations including risk factors, treatment delivered, and outcomes. Design: We designed a retrospective cross-sectional review of patients admitted to neurology with diagnosis of stroke or TIA from 2010 to 2015. Obtained variables were: age, sex, risk factors, acute therapy, National Institutes of Health Stroke Scale on admission and discharge, and disposition. Means, confidence intervals, or percentages were calculated as appropriate. Results: Around 1,457 patients were divided into two groups: younger than 80 (n = 968) and 80 and older (n = 487). Rates of stroke and TIA were similar across younger and older groups (11% versus 12% TIA and 89% versus 88% stroke, respectively). Younger patients had lower admission National Institutes of Health Stroke Scale (mean 4.64 versus 7.84 in older group) and greater improvement on discharge (mean change −1.51 versus −1.29 accordingly). Older patients received tissue-type plasminogen activator (tPA) more often than younger patients, but no difference in rates of thrombectomy between groups. Older patients were more likely to have hypertension, atrial fibrillation, coronary artery disease, and less likely to be a smoker. On discharge, younger patients with stroke were discharged home or to acute rehab more frequently, regardless of tPA administration. Conclusions: Older patients had more comorbidities, received tPA more often, and had worse outcomes regardless of use of intravenous tPA or thrombectomy, and were more frequently institutionalized after discharge.
