Insights
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.
Abstract:
Atrial fibrillation (AF) is an important risk factor for stroke and anticoagulation is now indicated in many patients at increased risk. Studies however have shown that many patients at risk are not anticoagulated for reasons that are not well explored. We identified prospectively the reasons for non-anticoagulation in patients with AF in 94 consecutive hospital patients with cardiac or cerebrovascular disease who had AF. Patients with intermittent or lone AF and < 60 years were excluded n = 16. The remaining group had a mean age of 76 +/- 7 years with a mental test score of 7.4 +/- 2 (normal 10), 31 lived alone and they lived an average of 14 +/- 11 miles from the hospital laboratory. The reasons for non-anticoagulation overlapped and were: medical in 29: cognitive impairment/compliance in 32: and monitoring problems in 50. Anticoagulation for AF in the elderly is a complex enterprise which must take into account social and cognitive as well as medical issues.
