ASCVD Risk Score Calculator

Example data table

Formula used

This calculator uses the 2013 ACC/AHA pooled cohort equations to estimate 10-year risk of a first “hard ASCVD” event for adults aged 40–79. Inputs are log-transformed, multiplied by race- and sex-specific coefficients, and combined into a linear predictor.

• Σ = sum of all (coefficient × value) terms for your profile.
• MeanΣ = group mean of Σ for the equation’s derivation sample.
• S₁₀ = baseline 10-year survival for the group.

Final risk is computed as: Risk = 1 − S₁₀ ^ exp( Σ − MeanΣ ).

How to use this calculator

1. Enter age, sex, and race group.
2. Enter total cholesterol and HDL-C (choose units if needed).
3. Enter systolic blood pressure and whether BP medication is used.
4. Select smoking and diabetes status.
5. Press “Calculate Risk” to see results above the form.
6. Use CSV/PDF buttons to save the latest result.

FAQs

1) What does ASCVD mean?

ASCVD refers to atherosclerotic cardiovascular disease, including heart attack, coronary death, and stroke. This tool estimates the 10-year risk of a first event.

2) Who should use this risk score?

It is designed for adults ages 40–79 without known ASCVD. It supports primary prevention discussions about lifestyle and medications.

3) Why do I enter cholesterol and HDL?

Total cholesterol and HDL-C strongly influence predicted risk. The equation uses natural logs of these values and age interactions for some groups.

4) How does blood pressure treatment change results?

The model uses different coefficients for treated versus untreated systolic blood pressure. For some groups, age and SBP interactions also apply.

5) What risk categories are shown?

Common categories are low (<5%), borderline (5–7.4%), intermediate (7.5–19.9%), and high (≥20%). Thresholds may vary by guideline and context.

6) Why can “Other” race use White coefficients?

The original equations were derived for non-Hispanic White and African-American adults. Many tools apply the White coefficients when an exact group is unavailable.

7) Can I use mmol/L units?

Yes. If you select mmol/L, the calculator converts cholesterol values using 1 mmol/L ≈ 38.67 mg/dL before applying the equation.

8) Is this a diagnosis or medical advice?

No. It is an educational estimate based on population data. Always interpret results with your clinician, especially if you have prior events or complex conditions.
