What percentage of first strokes are due to atrial fibrillation?In individuals experiencing a first stroke, atrial fibrillation (AFib) is a significant contributing factor, particularly in ischemic strokes, which account for the majority of all strokes.
Estimates vary slightly, but AFib is thought to be responsible for approximately:
- 22-25% of all strokes, especially in the elderly.
- 20% or more of acute ischemic strokes.
- Nearly 1 in 4 strokes in adults over 80.
The risk of stroke for people with AFib is significantly higher than those without the condition, increasing by as much as five times.Important notes:
- These figures are estimates, and the true percentage may be higher due to difficulties in diagnosing AFib, especially intermittent or silent cases.
- A stroke can also be the first symptom that leads to an AFib diagnosis.
- The risk of stroke in AFib patients is influenced by several factors like age, presence of other conditions like diabetes and high blood pressure, and whether it’s a first or recurrent stroke.
