APPLE Score (AF Recurrence After Ablation)
APPLE score (Kornej 2015): one point each for age > 65, persistent AF, impaired eGFR, dilated left atrium, and low ejection fraction; a higher score marks a higher risk of AF recurrence after catheter ablation.

Example
- Age > 65 years
- Yes
- Persistent AF
- Yes
- Impaired eGFR < 60 mL/min/1.73m²
- No
- LA diameter ≥ 43 mm
- No
- Ejection fraction < 50%
- No
Result: APPLE 2 — elevated recurrence risk after ablation.
The tool opens with these values already filled in. Replace them with your own.
What the result means
- 0-1
- Lower rate of AF recurrence after catheter ablation.
- >= 2
- Higher rate of AF recurrence. One point each: age > 65, persistent AF, eGFR < 60, LA >= 43 mm, EF < 50%. A recurrence-risk score, not an ablation order.
What you enter
- Age > 65 years (+1)
- Persistent AF (+1)
- Impaired eGFR < 60 mL/min/1.73m² (+1)
- LA diameter ≥ 43 mm (+1)
- Ejection fraction < 50% (+1)
