2022 ACR/EULAR Takayasu Arteritis Classification Criteria
2022 ACR/EULAR Takayasu arteritis classification (weighted, max 19); a cumulative score ≥ 5 classifies as Takayasu arteritis once both absolute requirements (age ≤ 60 at diagnosis and imaging evidence of vasculitis) are met.

Example
- Absolute requirement — age ≤ 60 years at diagnosis
- Yes
- Absolute requirement — evidence of vasculitis on imaging
- Yes
- Female sex
- Yes
- Angina or ischemic cardiac pain
- Yes
- Abdominal aorta with renal or mesenteric involvement
- Yes
Result: 2022 ACR/EULAR 6/19 — ≥ 5: classify as Takayasu arteritis.
The tool opens with these values already filled in. Replace them with your own.
What the result means
- Threshold
- a cumulative score ≥ 5 classifies as Takayasu arteritis (sensitivity 93.8%, specificity 99.2%).
What you enter
- Absolute requirement — age ≤ 60 years at diagnosis
- Absolute requirement — evidence of vasculitis on imaging
- Female sex (+1)
- Angina or ischemic cardiac pain (+2)
- Arm or leg claudication (+2)
- Vascular bruit (+2)
- Reduced pulse in upper extremity (+2)
- Carotid artery abnormality — reduced/absent pulse or tenderness (+2)
The other 4 fields
- Arm systolic blood-pressure difference ≥ 20 mmHg (+1)
- Symmetric involvement of paired arteries (+1)
- Abdominal aorta with renal or mesenteric involvement (+3)
- Number of affected arterial territories (one +1 / two +2 / three or more +3)
How this is calculated
- Items
- after both absolute requirements: aorta + renal/mesenteric +3; territories +1/+2/+3; five vascular signs +2 each; female sex, arm-SBP diff ≥ 20, symmetric arteries +1 each (max 19).
