About 15% of first-ever stroke survivors experience a recurrent stroke within 5 years, with the highest risk in the first 6 months. Advanced age, hemorrhagic stroke, and diabetes are key predictors. Early secondary prevention is crucial.
Area of Science:
- Neurology
- Epidemiology
- Public Health
Background:
- Limited community-based data exists on long-term recurrent stroke risk.
- Understanding recurrence risk is vital for effective stroke management.
Purpose of the Study:
- To determine the 5-year risk of first recurrent stroke after an initial stroke.
- To identify predictors of recurrent stroke in a population-based cohort.
Main Methods:
- Prospective registration and assessment of first-ever stroke and transient ischemic attack (TIA) cases.
- Follow-up of a defined population in Perth, Western Australia, for 5 years.
Main Results:
- 15% of first-ever stroke survivors experienced a recurrent stroke within 5 years.
- The risk of recurrent stroke was highest (8.8%) in the first 6 months post-stroke.
- Predictors included advanced age (75-84 years), hemorrhagic stroke, and diabetes mellitus.
Conclusions:
- Secondary prevention strategies should commence immediately after a first stroke due to high early recurrence risk.
- Recurrent stroke often shares the same pathological subtype as the index event.
- Identifying high-risk individuals (older age, specific stroke types, diabetes) can guide targeted interventions.
