Summary
Recurrent stroke patients face double the mortality risk compared to first-time stroke patients. However, survivors show similar recovery speeds and outcomes, unless the recurrent stroke is contralateral, leading to poorer functional recovery.
Area of Science:
- Neurology
- Epidemiology
- Public Health
Background:
- Recurrent stroke represents a significant clinical challenge.
- Understanding risk factors and prognosis for recurrent stroke is crucial for patient management.
Purpose of the Study:
- To compare stroke severity, risk factors, and prognosis between patients with recurrent versus first-ever stroke.
- To identify factors associated with stroke recurrence and outcomes.
Main Methods:
- Prospective study of 1,138 unselected acute stroke patients in the Copenhagen Stroke Study.
- Multivariate analysis to identify predictors of recurrence and compare outcomes.
Main Results:
- Recurrent stroke occurred in 23% of patients, often despite prophylactic treatment.
- Recurrence was linked to TIA history, atrial fibrillation, male gender, and hypertension.
- Recurrent stroke patients had nearly double the mortality rate but similar recovery speeds in survivors.
- Contralateral recurrent strokes resulted in poorer functional outcomes compared to ipsilateral recurrences.
Conclusions:
- Consistent anticoagulant therapy for atrial fibrillation and blood pressure control for hypertension are vital.
- Alternative prophylactic measures are needed when aspirin (ASA) is ineffective.
- Recurrent stroke significantly increases mortality, but functional recovery is comparable unless the recurrence is contralateral.
