This calculator estimates your risk of cardiovascular disease using the American Heart Association’s PREVENT equations — the model that, in 2025–2026, replaced the older Pooled Cohort Equations in US guidelines. It gives you two numbers that matter: your risk over the next 10 years and, if you’re under 60, your risk over the next 30 years — a genuine long-range view that older calculators never offered.
PREVENT is also race-free — it no longer uses race as an input — and folds in kidney function, making it more contemporary and more equitable than the tools it replaced.

This is an educational estimate, not a diagnosis. PREVENT is validated for adults aged 30–79 without existing cardiovascular disease, and was derived in a large US population — so it may not perfectly fit people of South- or East-Asian descent. It doesn’t capture family history, lipoprotein(a), ApoB or a coronary calcium score. Bring the result to your own doctor.
Method & limitations
Risk is computed from the American Heart Association’s PREVENT base equations (Khan SS et al., Circulation 2024;149:430–449), which estimate 10- and 30-year risk of total cardiovascular disease (and, separately, atherosclerotic CVD — heart attack and stroke) from age, sex, total and HDL cholesterol, systolic blood pressure and its treatment, diabetes, smoking, statin use and kidney function (eGFR). The 30-year estimate is only shown for ages 30–59, the range over which it is reported.
PREVENT was adopted into the 2025 ACC/AHA high-blood-pressure guideline and the 2026 ACC/AHA dyslipidemia guideline, replacing the older Pooled Cohort Equations. It is race-free by design. Limitations: it was derived in a US population and tends to be less accurate in some Asian groups; it doesn’t include family history, lipoprotein(a), ApoB or coronary calcium; and it is not validated below 30, above 79, or in people who already have cardiovascular disease. Treat the number as a prompt for a fuller assessment, not a verdict.
Frequently asked questions
What is the AHA PREVENT risk calculator?
PREVENT is the American Heart Association's cardiovascular risk model, introduced in 2023 and adopted into US guidelines in 2025–2026. It estimates your 10-year and 30-year risk of cardiovascular disease, is race-free, and includes kidney function.
What is a good 10-year cardiovascular risk?
Broadly, under 10% is lower risk, 10–20% moderate, and 20% or more higher risk over the next ten years. The right action depends on your age and overall health — for younger people the 30-year number is often more telling.
How is PREVENT different from the older risk calculators?
PREVENT replaced the older Pooled Cohort Equations. It is better calibrated to today's population, removes race as an input, adds kidney function, and uniquely gives a 30-year (lifetime-style) estimate for people aged 30–59.
