How this service works
CCS 2014 CHADS-65 algorithm for nonvalvular AF/AFL stroke-prevention discussion. Oral anticoagulant if age ≥65 or CHF, hypertension, diabetes, or prior stroke/TIA. Else aspirin if coronary, aortic, or peripheral arterial disease. Else none. Not CHADS2, not CHA2DS2-VASc, not HAS-BLED, and not an anticoagulation order. magent does not examine the patient.
Output
Returns the CHADS-65 algorithm recommendation: oral anticoagulant (OAC) if age ≥65 or any of CHF, hypertension, diabetes, or prior stroke/TIA are present; aspirin if OAC is not indicated but vascular disease is present; or no antithrombotic therapy if none of the above criteria apply. This is a discussion aid, not a clinical order.
Example use cases
Anticoagulation check for elderly AF patient
“My patient is 72 with nonvalvular atrial fibrillation, no CHF, no hypertension, no diabetes, no prior stroke or TIA, and no vascular disease — what does CHADS-65 say about stroke prevention therapy?”
Aspirin vs OAC for AF patient with vascular disease
“I have a 58-year-old AF patient with known coronary artery disease but no CHF, hypertension, diabetes, or prior stroke — run CHADS-65 and tell me if aspirin or anticoagulation is recommended.”
Stroke prevention for younger diabetic AF patient
“Patient is 55 with nonvalvular atrial flutter, diabetes mellitus, no hypertension, no CHF, no prior stroke or TIA, and no vascular disease — what does the CHADS-65 algorithm recommend for stroke prevention?”

Endpoint
GEThttps://api.magentlab.com/api/calc/chads_65When to prefer
Choose this endpoint when you need to apply specifically the CCS 2014 CHADS-65 guideline for nonvalvular AF or AFL stroke prevention triage — not CHADS2, CHA2DS2-VASc, or HAS-BLED. Ideal for Canadian guideline-aligned clinical decision support tools or educational discussion aids.
Side effects
- Missing required query parameters (age, chf, hypertension, diabetes, stroke_tia, vascular_disease) returns a validation error
- Age outside integer range 18–120 may produce unexpected results or rejection
- Boolean fields passed as non-boolean strings may fail schema validation
- Payment failure (HTTP 402) if USDC payment is not provided or is insufficient
