How this service works
O'Mahony 2014 HCM Risk-SCD: 5-year SCD probability from wall thickness, LA diameter, LVOT gradient, family history of SCD, NSVT, unexplained syncope, and age. Returns prognostic_index, five_year_scd_risk_percent, and 4%/6% risk_band (lower / intermediate / higher). Not an ICD or device order. Not a medical device.
Output
Returns a JSON object with three fields: prognostic_index (the continuous linear predictor value), five_year_scd_risk_percent (the model-derived 5-year absolute risk of sudden cardiac death as a percentage), and risk_band (categorical classification: 'lower' for <4%, 'intermediate' for 4–6%, or 'higher' for ≥6%) — enabling downstream risk-based decision support without constituting a device order or ICD recommendation.
Example use cases
Pre-ICD counseling risk quantification
“I have a 38-year-old HCM patient I'm considering for ICD discussion — max LV wall thickness 28 mm, LA diameter 42 mm, LVOT gradient 15 mmHg, no family history of SCD, NSVT present on Holter, and no syncope. What does the O'Mahony 2014 model give for their 5-year SCD risk and which risk band do they fall in?”
Asymptomatic HCM patient annual review
“My 60-year-old asymptomatic HCM patient has a wall thickness of 14 mm, LA diameter of 38 mm, resting LVOT gradient of 5 mmHg, no family history of sudden death, no NSVT, and no syncope. Can you run the ESC HCM Risk-SCD score so I have a documented risk estimate for their chart?”
High-risk feature triage in HCM clinic
“I'm triaging a 25-year-old with HCM — max wall thickness 30 mm, LA diameter 55 mm, LVOT gradient of 80 mmHg, family history of SCD positive, NSVT seen, and one episode of unexplained syncope last year. Calculate the O'Mahony 5-year SCD probability and tell me the risk band.”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/hcm_risk_scdWhen to prefer
Use this endpoint when you need to compute the ESC-endorsed O'Mahony 2014 HCM Risk-SCD score specifically — it implements the validated continuous-predictor logistic model with the 4%/6% risk bands as published, suitable for documentation and audit. Prefer this over generic risk calculators when the clinical context is hypertrophic cardiomyopathy and the required 7 predictors are already available from echocardiography and clinical history.
Side effects
- Age outside 16–80 range returns a validation error
- Max wall thickness outside 10.0–35.0 mm returns an out-of-range error
- LA diameter outside 20.0–70.0 mm returns a validation error
- LVOT gradient outside 0.0–154.0 mmHg returns a validation error
- Missing any required query parameter returns a 400 bad request
- Non-integer age or non-boolean flag fields return a type validation error
