x402
magent HFA-ICOS HER2 Baseline Cardiovascular Risk Calculator is a paid API for AI agents from api.magentlab.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-14).
Classifies baseline cardiovascular risk (Very High / High / Medium 1 / Medium 2 / Low) before HER2-targeted therapy (trastuzumab and related agents) per the Lyon 2020 HFA-ICOS published criteria.

How this service works
Lyon 2020 HFA-ICOS baseline cardiovascular risk before HER2-targeted therapy (trastuzumab and related agents). Very high, high, medium, or low from published factors plus Medium 1/2 points; expert-opinion cardiotoxicity guide <2% / 2-9% / 10-19% / >=20%. Concurrent anthracycline is High; sequential anthracycline before HER2 is Medium 1. Deterministic published classification with citation; not a treatment order. magent does not measure LVEF or biomarkers.
Output
Returns a deterministic cardiovascular risk category (Very High, High, Medium 1, Medium 2, or Low) per Lyon 2020 HFA-ICOS published classification, an estimated cardiotoxicity incidence band (<2%, 2-9%, 10-19%, or >=20%), the specific factors driving the classification, and the published citation. Does not measure LVEF or biomarkers directly — these are caller-supplied.
Example use cases
Pre-treatment trastuzumab risk stratification
“My patient is 68 years old with LVEF 55%, has hypertension and diabetes, is not obese, no CKD, no arrhythmia, no elevated troponin or BNP, no history of heart failure, MI, CABG, stable angina, or valvular disease, no prior trastuzumab cardiotoxicity, no concurrent or sequential anthracycline, no prior chest radiation, and is a non-smoker. What is her baseline cardiovascular risk category before starting trastuzumab under the Lyon 2020 HFA-ICOS framework?”
High-risk flagging with concurrent anthracycline
“A 55-year-old breast cancer patient is about to receive concurrent anthracycline and HER2-targeted therapy. LVEF is 60%, no heart failure or prior trastuzumab cardiotoxicity, no MI, CABG, angina, or valvular disease, no arrhythmia, normal troponin and BNP, no prior anthracycline or chest radiation, no hypertension, diabetes, CKD, smoking, or obesity. What does the HFA-ICOS HER2 classification say about her baseline cardiac risk and estimated cardiotoxicity incidence?”
Sequential anthracycline prior to HER2 therapy
“Patient is 61 years old, LVEF 62%, received anthracycline chemotherapy sequentially before HER2 therapy, no concurrent anthracycline now, no heart failure, no prior trastuzumab toxicity, no MI or CABG, no angina or valvular disease, no arrhythmia, troponin and BNP normal, no prior chest radiation, has hypertension but no diabetes, no CKD, non-smoker, not obese. Using the Lyon 2020 HFA-ICOS criteria, classify this patient's baseline cardiovascular risk before HER2-targeted therapy.”

Endpoint
GEThttps://api.magentlab.com/api/calc/hfa_icos_her2When to prefer
Use this endpoint when you need a deterministic, citation-backed cardiovascular risk classification per the Lyon 2020 HFA-ICOS framework specifically for HER2-targeted therapy (trastuzumab and related agents). Prefer it over generic risk calculators when the clinical context is pre-HER2 therapy cardiotoxicity risk stratification, especially when the treating team has already assessed clinical variables and needs a structured tier (Very High / High / Medium 1 / Medium 2 / Low) with an associated cardiotoxicity incidence estimate and literature citation. Not appropriate for LVEF measurement, biomarker assay, treatment ordering, or non-HER2 chemotherapy risk stratification.
Side effects
- Missing required query parameters (age_years, lvef_percent, or any boolean flag) returns a validation error
- Age outside the 18-100 integer range may return an error or unexpected classification
- Caller misassigns clinical variables (e.g. arrhythmia, troponin elevation) — garbage-in garbage-out; endpoint trusts caller-supplied booleans
- Payment failure (x402) returns 402 status with payment instructions rather than a risk classification
- Conflicting flag combinations (e.g. both concurrent and sequential anthracycline) may produce unexpected tier assignments
