Abstract P218: Long-term Risk Of Recurrent Stroke After Ischemic Stroke Among Younger Adults Under 55 Years Of Age, Sweden
Purpose: The purpose of the present study was to investigate the 4-year risk of recurrent stroke among patients below 55 years with a first ischemic stroke (IS), 1987-2006.
Methods: All men and women (17,149 cases) aged 18-54 years who survived at least 28 days after a first IS were identified in the Swedish Inpatient register (IPR) from 1987 until 2006. All patients were followed-up at 1 year, 2 years, 3 years and 4 years for a first recurrent stroke after index event.
Results: From 1987 to 2006 a total of 1808 first recurrent stroke were identified. Long-term risk of a first recurrent stroke declined over time in both men and women. Among men, the absolute 4-year cumulative risk of a recurrent stroke decreased from 17.5% (95% CI 15.7%-19.4%) to 8.8% (95% CI, 7.7%-10.0%) from the first to the last 5-year period. Corresponding result for women was 15.6% (95% CI, 13.3%-18.2%) and 6.0% (95% CI, 4.9%-7.3%). Despite an overall decrease, the risk of a recurrent stroke was highest during the first year after index stroke (men=3.9%, 95% CI, 3.3%-4.8%, women=2.9%, 95% CI, 2.2%-3.8%).
Conclusions: Over the 20-year period, the 4-year cumulative risk of a first recurrent stroke decreased over time. For both men and women the risk was greatest during the first year, emphasizing the importance of early secondary prevention in young stroke victims.
