ABSTRACT
BACKGROUND AND PURPOSE:
Thrombolysis for acute ischemic stroke in the elderly population is seldom administered.METHODS:
In this study, we evaluated the risks of thrombolysis, including the mortality and intracerebral hemorrhage (ICH) rates in this population. A cohort of patients was identified from the National Inpatient Sample database for the years 2000-2006. Age was categorized in 2 groups, including those between 18 and 80 years and those >80 years. Multivariate logistic regression analysis was used to assess covariates associated with hospital mortality and ICH. A total of 524 997 patients were admitted for acute ischemic stroke; 143 093 (27.2%) were >80 years. A total of 7950 patients were treated with thrombolysis, of which 1659 (20.9%) were >80 years. Elderly patients received less frequent thrombolysis compared with the younger population (1.05% versus 1.72%).RESULTS:
In the whole cohort, the mortality rate was higher in the older population (12.80% versus 8.99%). For those treated with thrombolysis, the mortality rate and risk of ICH were higher among those >80 years (16.9% versus 11.5%; odds ratio 1.56 [95% CI 1.35 to 1.82] and 5.73% versus 4.40%; odds ratio 1.31 [95% CI 1.03 to 1.67], respectively). Multivariate logistic regression analysis showed that the presence of ICH (odds ratio 2.24 [95% CI 1.89 to 2.65]) was associated with higher mortality rates but not the use of thrombolysis (odds ratio 1.14 [95% CI 0.98 to 1.33]).CONCLUSIONS:
Despite the higher mortality rate in the older population, the use of thrombolysis does not predict death; however, the use of thrombolysis was associated with high risk of ICH.
