Insights
Anticoagulation (AC) treatment significantly reduces mortality risk in hospitalized stroke patients with atrial fibrillation (AF). The study found under-use of AC in elderly patients, leading to a doubled risk of death.
Area of Science:
- Cardiology
- Neurology
- Public Health
Context:
- Atrial fibrillation (AF) is a common condition associated with increased stroke risk.
- Effective anticoagulation (AC) is crucial for preventing stroke-related mortality in AF patients.
- This study examines AC utilization and outcomes in a Danish stroke registry.
Purpose:
- To assess the utilization of anticoagulation (AC) in hospitalized stroke patients with atrial fibrillation (AF).
- To determine the association between AC treatment and mortality risk in this patient population.
- To identify factors influencing AC prescription and highlight potential under-use.
Summary:
- A Danish registry identified 1,909 stroke patients with AF eligible for anticoagulation (AC).
- AC was administered to 60.2% of patients, influenced by age and stroke severity.
- Cox regression analysis revealed a doubled mortality risk (HR=1.91) for patients not receiving AC.
Impact:
- The findings indicate a significant under-utilization of AC in elderly stroke patients with AF.
- This under-use is linked to increased mortality, emphasizing the need for improved treatment guidelines.
- Optimizing AC therapy in AF stroke patients can potentially save lives and reduce healthcare burdens.
Abstract:
A registry of hospitalized stroke patients in Denmark included 1,909 patients with stroke and atrial fibrillation (AF) without contraindications to anticoagulation (AC) treatment. AC instituted in 60.2% was significantly associated to age and stroke severity. In a Cox Proportional Hazard regression model the risk of death was doubled in patients who had no AC treatment (HR =1.91, 95% CI=1.44 to 2.52). The study indicates under-use of AC in elderly stroke patients with AF, leading to increased mortality.
