Summary
This study found that atrial fibrillation (AF) affects 1% of the community, with warfarin use increasing. However, guideline adherence for anti-thrombotic management in AF patients remains suboptimal, particularly in moderate and low-risk groups.
Area of Science:
- Cardiology
- Epidemiology
- Public Health
Background:
- Atrial fibrillation (AF) is a common cardiac arrhythmia.
- Effective management of AF-related stroke risk is crucial.
Purpose of the Study:
- Determine the prevalence of atrial fibrillation (AF) in a community.
- Assess current anti-thrombotic management against established guidelines.
Main Methods:
- Cross-sectional community-based study.
- Identified 1466 patients with AF; 1008 consented.
- Collected demographic and medical history data.
Main Results:
- AF prevalence was 1% (1466 patients, mean age 73.4, 55% female).
- 53% of AF patients were on warfarin; one-third of non-warfarin users had contraindications.
- Warfarin use increased with stroke risk and over the study period.
Conclusions:
- AF prevalence aligns with prior research.
- Increasing warfarin use in AF patients observed.
- Deviations from guidelines noted in moderate and low-risk groups, especially in elderly patients.
