How this service works
ESC 2024 CHA2DS2-VA stroke-risk score from age and discrete flags (CHF, hypertension, diabetes, prior stroke/TIA, vascular disease). No sex category (not CHA2DS2-VASc). Score 0 none, 1 consider OAC, ≥2 OAC recommended. Deterministic published arithmetic with citation; not an anticoagulation order.
Output
Returns the integer CHA2DS2-VA score (0–9) computed from the provided age bracket and five clinical flags, along with an interpretation: score 0 means no anticoagulation needed, score 1 means consider oral anticoagulant (OAC), and score ≥2 means OAC is recommended per ESC 2024 guidelines. The calculation is deterministic published arithmetic and does not constitute a clinical order.
Example use cases
AFib patient OAC decision support
“My patient is 68 years old with atrial fibrillation, has a history of hypertension and a prior MI — no CHF, no diabetes, no prior stroke or TIA. What is their CHA2DS2-VA score and should we consider starting anticoagulation?”
Post-stroke high-risk patient triage
“Can you score a 77-year-old AFib patient who had a TIA last year and also has congestive heart failure and hypertension? No diabetes, no vascular disease. I need the CHA2DS2-VA total and the ESC guideline recommendation.”
Low-risk patient anticoagulation screening
“I have a 62-year-old AFib patient with no CHF, no hypertension, no diabetes, no prior stroke, and no vascular disease. Run the CHA2DS2-VA score and tell me if anticoagulation is needed.”

Endpoint
GEThttps://api.magentlab.com/api/calc/cha2ds2_vaWhen to prefer
Use this endpoint when you need the ESC 2024 version of the CHA2DS2-VA score (which excludes the sex/female category present in CHA2DS2-VASc) for atrial fibrillation stroke risk stratification. Prefer this over CHA2DS2-VASc calculators when following the updated ESC 2024 guideline that dropped sex as a risk modifier. Ideal for clinical decision support tools, EHR integrations, and automated patient triage workflows where a fast, deterministic, cited arithmetic result is needed.
Side effects
- Missing required query parameters (age, chf, hypertension, diabetes, stroke_tia, vascular_disease) returns a 400 error
- Age outside 18–120 range may return a validation error
- Non-boolean values for flag parameters cause schema validation failure
- Payment not provided or x402 header missing causes 402 Payment Required
- Network timeout or server error returns 5xx
