title: Comparison of epidemiology, emergency care, and outcomes of acute ischemic stroke between young adults and elderly in Korean population: a multicenter observational study.
abstract: Stroke in young adults has been known to show a lower incidence and a better prognosis. Only a few studies have examined the epidemiology and outcomes of ischemic stroke in young adults and compared them with the elderly in Korean population. All consecutive patients with ischemic stroke visiting 29 participating emergency departments were enrolled from November 2007 to October 2009. Patients with less than 15 yr of age and unknown information on age and confirmed diagnosis were excluded. We categorized the patients into young adults (15 to 45 yr) and elderly (46 yr and older) groups. Of 39,156 enrolled all stroke patients, 25,818 with ischemic stroke were included and analyzed (young adult; n=1,431, 5.5%). Young adult patients showed lower prevalence of most chronic diseases but significantly higher prevalence in exercise, current smoking, and alcohol consumption. Hospital mortality was significantly lower in young adults than elderly (1.1% vs. 3.1%, P<0.001). Higher number of patients in elderly group (68.1%) showed worsening change of modified Rankin Scale than young adults (65.2%). Young adults ischemic stroke showed favorable hospital outcomes than the elderly in Korean population.
