ASCVD Risk Calculator

Estimate 10-year ASCVD risk for adults 40-79 with the 2013 ACC/AHA Pooled Cohort Equations. Lipids, BP, smoking, diabetes. Educational only.

Patient details

Equations are validated for ages 40 to 79. Outside that range the estimate is an extrapolation.

The 2013 Pooled Cohort Equations only publish coefficients for these two groups. People of other backgrounds default to the white or other coefficients in the original publication.

Risk factors

10-year ASCVD risk

5.4%

Borderline risk (5% to 7.4%)

10-year risk is borderline (5% to 7.4%). Discuss risk-enhancing factors with your clinician (family history of premature ASCVD, persistent LDL above 160 mg/dL, chronic kidney disease, metabolic syndrome, inflammatory conditions, persistently elevated triglycerides, lipoprotein(a), or apoB). A coronary artery calcium (CAC) score can refine the decision about starting a statin.

Medical disclaimer

This calculator is a screening estimate for educational use only. It is not a diagnosis, prescription, or treatment plan. The 2013 ACC/AHA Pooled Cohort Equations were derived from older US cohorts and have been shown to overestimate risk in some populations. Race in the equation is a statistical proxy, not biology, and the coefficients only exist for two groups. Lipid values vary with fasting state, illness, and lab assay. Decisions about statins, blood pressure treatment, aspirin, lifestyle changes, or any other intervention belong with a qualified clinician who can review your full history, family history, risk-enhancing factors, and current medications. If you have chest pain, shortness of breath, or other symptoms of cardiovascular disease, seek medical care immediately.

Frequently Asked Questions about the ASCVD Risk Calculator

What is the ASCVD risk score?
The ASCVD (atherosclerotic cardiovascular disease) risk score estimates your 10-year probability of a first heart attack or stroke. It uses the 2013 ACC/AHA Pooled Cohort Equations, the standard US tool for primary prevention decisions about statins and aspirin.
Who should use this calculator?
Adults 40 to 79 without prior ASCVD events. The equations were derived from US cohorts and are validated for white and Black populations; for other ethnicities they tend to overestimate. People under 40 or over 79, or with existing ASCVD, should use other tools.
What counts as high risk?
ACC/AHA categories: <5% low, 5-7.5% borderline, 7.5-20% intermediate, >=20% high. For intermediate risk, guidelines recommend discussing statins with your clinician. For high risk, statin therapy is typically recommended unless contraindicated.
Why do the equations use four subgroups?
Risk patterns differ by sex and race. The 2013 equations include separate coefficients for white men, Black men, white women, and Black women. "White" is used as the default for other ethnicities, with the caveat that risk is likely overestimated.
Is the score reliable?
It is the best validated US tool for primary prevention but has limits: it may overestimate in modern cohorts (medical care has improved since the derivation data), and it does not include family history, coronary calcium score, lipoprotein(a), or inflammatory markers. Use it as a starting point, not a verdict, and talk through results with your clinician. Educational only.
