New data reveal that 85% of children were alive 5 years after a pediatric stroke. However, children who sustained a hemorrhagic stroke were at much higher risk for mortality compared with those who sustained an ischemic stroke.
Researchers examined demographic and clinical data on 1,034 children admitted to hospitals with a first-time diagnosis of stroke from 1994 to 2007. At 30 days, the mortality rate was 10.2% vs. 13.7% at 1 year and 16.2% at 5 years.
At all time points examined, mortality rates associated with hemorrhagic stroke were two to three times higher vs. ischemic stroke (P<.0001).
Cerebrovascular hemorrhage and congenital malformations of the circulatory system were the determined cause of death in 24% of cases; the remainder was attributed to cancer and disease or malformations of the nervous system.
Type of stroke, prior history of cardiac dysrhythmia, central nervous system tumor, leukemia, HIV and meningitis were identified as important predictors of mortality after the researchers adjusted for all covariates.
The data were compiled using New Jersey hospital admissions included in the Myocardial Infarction Data Acquisition System (MIDAS). Within 30 days, 1 year and 5 years from index submission, researchers matched MIDAS records to death information from New Jersey death registration files.
