Epidemiology update: Stroke and AF
- Framingham Heart Study investigators examined the impact of AF on stroke risk in 5184 male and female participants.1
- Age-specific prevalence rates increased steadily from 1.8% for ages 60-69 years to 10.2% for ages 80-89 years.
- In each age group, stroke rates were approximately 5-fold higher in groups with AF compared with groups without AF.
- The percent of total stroke events attributed to AF (population attributable risk) increased from 7.3% in 60-69 years age group to 30.8% in the 80-89 years age group.
