ASCVD 10-year risk calculator
Estimate the 10-year chance of a heart attack or stroke with the American Heart Association's PREVENT equations, from age, sex, cholesterol, blood pressure, kidney function, and a few yes or no questions. An estimate for a population, not a prediction about one person.
Medically reviewed by Kevin Brandstetter, M.D.Updated September 23, 2026
The equations were derived for adults aged 30 to 79.
Estimated glomerular filtration rate. It comes from a basic metabolic panel and is printed on the lab report.

The estimate appears here once age, sex, both cholesterol numbers, systolic blood pressure, and eGFR are filled in.
This is an estimate for a population of people like the numbers entered, not a prediction about you. Discuss your result with a clinician.
A calculator, not a diagnosis.
This estimate describes how often people with numbers like the ones entered had a heart attack or stroke within 10 years in large studies. It is not a prediction about one person. The equations were built for adults aged 30 to 79 who have never had a heart attack, a stroke, or another cardiovascular disease. A licensed clinician reads an estimate like this alongside your history, not instead of it.
Methodology
- How this is calculated
- The page uses the American Heart Association's PREVENT equations, the sex-specific 10-year model for atherosclerotic cardiovascular disease (heart attack, death from coronary heart disease, or stroke) in its base form. The equation's predictors are age, total and HDL cholesterol, systolic blood pressure, eGFR, diabetes, current smoking, blood pressure treatment, and statin use. Each is centered and scaled as the paper publishes it, cholesterol is converted to mmol/L with the paper's own factor (0.02586), and the weighted sum becomes a percentage through the logistic function. The result is shown to one decimal. The equations accept systolic pressures up to 200 mmHg; this page stops at 180, because a reading above 180 calls for prompt care rather than a 10-year estimate.
- Where the data comes from
- Khan SS, Matsushita K, Sang Y, et al., Development and Validation of the American Heart Association's PREVENT Equations, Circulation 2024;149(6):430-449. Coefficients from its Supplemental Table S12A (base model, 10-year ASCVD), with the input ranges that table states: age 30 to 79, total cholesterol 130 to 320 mg/dL, HDL cholesterol 20 to 100 mg/dL, and eGFR 15 to 150. The paper publishes no risk categories, and this page adds none: the familiar risk bands come from separate treatment guidelines, where they are decision thresholds, so this page prints the percentage alone.

- What this does not account for
- Family history, lipoprotein(a), coronary calcium, kidney albumin, blood sugar levels, and every other fact a clinician weighs. The PREVENT equations also have optional versions with extra inputs and 30-year versions; this page uses the base 10-year model only. The equations were not built for people who already have cardiovascular disease.
What the number means
A 10-year estimate of 5% means that among 100 people with the same numbers, about 5 would be expected to have a heart attack or stroke in the next 10 years. It does not say which 5, and it cannot say whether you will be one of them.
Where the numbers come from
Total and HDL cholesterol are on a standard lipid panel. eGFR, an estimate of kidney function, is printed on a basic or comprehensive metabolic panel. Systolic blood pressure is the top number of a reading. The PREVENT equations include kidney function, and they do not ask about race.
Discuss your result with a clinician, who can read it alongside what this page cannot see.
