Heart Disease Risk Calculator (AHA PREVENT 10-Year)
Estimate your 10-year risk of heart attack, stroke and heart failure with the American Heart Association's PREVENT equations (2023) — for adults aged 30–79, using age, cholesterol, blood pressure, diabetes, smoking, kidney function and BMI.
For general information only — not medical advice. Results are estimates; talk to a doctor or qualified health professional about your own health.
How to use
- 1Enter your age, sex, cholesterol (total and HDL) and blood pressure from a recent check-up.
- 2Tick diabetes, smoking and any blood-pressure or statin medicines.
- 3Enter eGFR from your kidney blood test and your BMI, then discuss the result with your doctor.
How it's calculated
PREVENT base model: sex-specific logistic equations with centred terms for age, non-HDL and HDL cholesterol, systolic blood pressure, diabetes, smoking, BMI, eGFR, blood-pressure and statin treatment, and age interactions. Risk = eˣ ÷ (1 + eˣ).
Frequently asked questions
What do the results mean?
The percentage chance of a first cardiovascular event over 10 years. For total CVD, the AHA describes under 5% as low, 5–7.4% borderline, 7.5–19.9% intermediate and 20% or more as high risk.
How is PREVENT different from the older ASCVD calculator?
It adds heart failure and kidney function (eGFR), removes race, is based on a larger modern population, and tends to give lower risk estimates than the 2013 Pooled Cohort Equations.
Can I use it if I already have heart disease?
No — it's for people without known cardiovascular disease. If you've had a heart attack or stroke, your risk is already high and your doctor will manage it differently.
