Insights
Atrial fibrillation (AF) increases stroke risk. Oral anticoagulation (OAC) therapy is crucial for stroke prevention in AF patients, but its use remains inadequate, necessitating improved risk assessment and timely OAC initiation.
Area of Science:
- Cardiology
- Neurology
- Public Health
Background:
- Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia.
- AF significantly increases the risk of stroke and thromboembolism, leading to severe outcomes and high healthcare costs.
Purpose of the Study:
- To highlight the critical importance of stroke prevention in atrial fibrillation management.
- To underscore the inadequacy of thromboprophylaxis despite strong evidence for oral anticoagulation (OAC) benefits.
Main Methods:
- Review of current strategies for stroke risk stratification in AF patients.
- Analysis of factors contributing to the underutilization of OAC therapy.
Main Results:
- Strokes in AF patients are often more severe, causing prolonged hospitalization and disability.
- Despite proven efficacy, OAC use for stroke prevention in AF is insufficient.
Conclusions:
- Effective stroke prevention in AF requires comprehensive strategies.
- Key measures include accurate risk assessment, prompt OAC initiation and adherence, early AF detection, and patient/physician education, particularly for the elderly.
Abstract:
Atrial fibrillation (AF) is the commonest sustained cardiac arrhythmia and is associated with increased morbidity and mortality due to stroke and thrombo-embolism. In patients with AF, strokes are usually more severe, resulting in longer hospital stays, worse disability and considerable healthcare costs. The prevention of stroke therefore is crucial in the management of AF. Stroke risk stratification tools can be used to determine patients at higher risk of stroke, and if no contraindications are present oral anticoagulation (OAC) therapy can be initiated. Despite the strong evidence for the benefit of OAC in stroke prevention in patients with AF, the use of thromboprophylaxis remains inadequate. The key measures to prevent stroke in patients with AF include: adequate stroke risk assessment and thrombo-prophylaxis; prompt initiation of OAC and avoidance of interruptions; earlier detection of AF; and education to overcome the under-usage of OAC in elderly patients.
