How this service works
Fox 2017 GARFIELD-AF 1-year all-cause mortality, ischaemic stroke/systemic embolism, and major bleed from age, sex, weight, pulse, diastolic BP, comorbidities, smoking, caller-assigned ethnicity (White/Caucasian reference; Hispanic/Latino, Asian, Black/Mixed/Other), oral anticoagulant class (none, NOAC, VKA), carotid occlusive disease, and antiplatelet therapy. Published 1-year equations. magent does not assign race or ethnicity. Not a diagnosis or anticoagulation order.
Output
Returns three 1-year probability estimates computed from the published Fox 2017 GARFIELD-AF linear predictors: (1) all-cause mortality, (2) ischaemic stroke or systemic embolism, and (3) major bleeding. Values are derived from the patient's age, sex, weight, pulse, diastolic BP, comorbidity flags, smoking status, ethnicity, OAC class, carotid occlusive disease, and antiplatelet use. The endpoint does not recommend anticoagulation or diagnose AF.
Example use cases
AF patient on warfarin risk stratification
“Run the GARFIELD-AF Fox 2017 risk model for a 68-year-old female, 70 kg, pulse 95 bpm, diastolic BP 78 mmHg, Asian ethnicity, with vascular disease and type 2 diabetes, no prior stroke, no bleeding history, no CKD, no dementia, current smoker, on VKA, no carotid occlusive disease, and taking antiplatelet therapy — give me her 1-year mortality, stroke, and bleed risks.”
Newly diagnosed AF patient not on anticoagulant
“Calculate the 1-year mortality, ischaemic stroke, and major bleed probabilities using GARFIELD-AF for a 58-year-old male, 95 kg, pulse 110 bpm, diastolic BP 90 mmHg, Hispanic/Latino ethnicity, with prior stroke and moderate CKD, no heart failure, no bleeding history, no diabetes, no dementia, non-smoker, currently on no oral anticoagulant, and no antiplatelet or carotid occlusive disease.”
Elderly AF patient with multiple comorbidities
“Use the Fox 2017 GARFIELD-AF equations to estimate 1-year all-cause mortality, stroke/embolism risk, and bleeding risk for an 81-year-old female, 62 kg, pulse 72 bpm, diastolic BP 70 mmHg, Black/Mixed/Other ethnicity, with heart failure, dementia, prior stroke, history of bleeding, and diabetes, moderate-to-severe CKD, no current smoking, on a NOAC, carotid occlusive disease present, no antiplatelet.”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/garfield_afWhen to prefer
Use this endpoint when you need the validated, published Fox 2017 GARFIELD-AF 1-year absolute risk estimates for mortality, stroke/embolism, and major bleeding in patients with atrial fibrillation. Prefer this over generic CHA2DS2-VASc or HAS-BLED calculators when you need simultaneous estimates of all three outcomes from a large real-world registry model. This is appropriate when you have all required clinical parameters available and want a research-grade, citation-backed computation rather than a simple score.
Side effects
- Missing required query parameters (age, sex, weight_kg, pulse, diastolic_bp_mm_hg, comorbidity flags, oac, ethnicity, carotid_occlusive_disease, antiplatelet) returns a 400 Bad Request
- Age outside the 18-120 range or pulse outside 30-250 may return a validation error
- Invalid enum values for sex, oac, or ethnicity return an error
- Payment not provided or insufficient USDC balance results in 402 Payment Required
- Network timeout or server unavailability returns 5xx error
