Summary
Many elderly patients with atrial fibrillation (AF) are not anticoagulated due to medical, cognitive, and monitoring issues. Addressing these barriers is crucial for stroke prevention in this population.
Area of Science:
- Cardiology
- Geriatrics
- Neurology
Background:
- Atrial fibrillation (AF) significantly increases stroke risk.
- Anticoagulation is recommended for high-risk AF patients.
- Many at-risk patients are not receiving anticoagulation, with reasons often unexplored.
Purpose of the Study:
- To prospectively identify reasons for non-anticoagulation in elderly patients with AF.
- To analyze the contributing factors to underutilization of anticoagulation therapy in this demographic.
Main Methods:
- Prospective identification of non-anticoagulation reasons in 94 consecutive hospital patients with AF.
- Exclusion of patients with intermittent/lone AF or under 60 years old.
- Analysis of medical, cognitive, compliance, and monitoring-related barriers.
Main Results:
- The study group had a mean age of 76 years, with cognitive impairment (mean test score 7.4/10).
- Many patients lived alone and were geographically distant from the laboratory.
- Overlapping reasons for non-anticoagulation included medical (29), cognitive/compliance (32), and monitoring issues (50).
Conclusions:
- Anticoagulation for elderly AF patients is complex, involving medical, social, and cognitive factors.
- Cognitive impairment and monitoring challenges are significant barriers to anticoagulation.
- A multidisciplinary approach is needed to optimize stroke prevention in elderly AF patients.
