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

The equation is limited to ages 40 to 79.

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%)

The Pooled Cohort Equations place this estimate between 5% and 7.4%. Use this model result as one input to a clinical discussion.

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.

10-Year ASCVD Risk Bands

The calculator groups the 2013 ACC/AHA Pooled Cohort Equation result into these bands.

This educational estimate cannot replace a clinician's assessment. It is not validated for every population or clinical situation.

Frequently Asked Questions about the ASCVD Risk Calculator

What is the ASCVD risk score?
This calculator implements the 2013 Pooled Cohort Equations to estimate 10-year risk of a first atherosclerotic cardiovascular disease event. That is now a legacy model. Current 2026 AHA and ACC prevention guidance uses the newer PREVENT equations for primary prevention risk assessment. Do not treat this result as a current treatment recommendation.
Who should use this calculator?
The implemented Pooled Cohort Equations were designed for adults ages 40 to 79 without prior ASCVD and provide separate coefficients for Black and White populations. Their calibration does not transfer reliably to every person or population. Current clinical assessment should use PREVENT where applicable and account for medical history, laboratory data, and clinician judgment.
What counts as high risk?
The calculator labels legacy Pooled Cohort Equation results below 5 percent as low, 5 to under 7.5 percent as borderline, 7.5 to under 20 percent as intermediate, and 20 percent or more as high. Those labels do not by themselves determine medication. Current prevention decisions use PREVENT risk plus factors such as LDL cholesterol, diabetes, kidney disease, family history, and coronary artery calcium when appropriate.
Why do the equations use four subgroups?
The 2013 equations were fitted separately for Black women, Black men, White women, and White men. The calculator requires one of those legacy coefficient sets, but selecting White for another ethnicity is not a validated individual substitute. PREVENT was designed without race as an input and is the current model for relevant US primary prevention decisions.
Is the score reliable?
The result can reproduce the 2013 Pooled Cohort Equations, but that does not make it a current or individualized clinical estimate. Calibration varies by population, and the model omits factors that can change a prevention decision. Use a current PREVENT assessment with a clinician rather than relying on this calculator for statin, aspirin, or other treatment choices.
