ASCVD Risk Calculator
ASCVD risk calculator estimates your 10-year risk of a first cardiovascular event such as heart attack or stroke. Risk categories range from low (below 5%) to high (above 20%), guiding statin therapy decisions.

How it works: Calculates individual risk based on age, cholesterol, blood pressure, diabetes, and smoking status.
Worked Example
Understanding Your ASCVD Risk Score
The ASCVD (Atherosclerotic Cardiovascular Disease) risk calculator uses the Pooled Cohort Equations to estimate your 10-year probability of a first cardiovascular event, such as a heart attack or stroke.
- Low risk: below 5% (lifestyle modifications recommended)
- Borderline risk: 5% to 7.5% (consider risk-enhancing factors)
- Intermediate risk: 7.5% to 20% (statin therapy discussion recommended)
- High risk: above 20% (high-intensity statin therapy generally recommended)
- Validated for adults aged 40 to 79 years
- Risk-enhancing factors like family history and coronary calcium score can refine borderline results
The ASCVD risk score is one component of cardiovascular risk assessment. Treatment decisions should involve a shared discussion between patient and clinician. This tool is for educational purposes only.
You can also calculate changes using our Target Heart Rate Calculator or HEART Score Calculator.
10-Year ASCVD Risk Categories and Statin Therapy Guidelines
Risk categories based on the Pooled Cohort Equations for atherosclerotic cardiovascular disease. Used to guide statin therapy initiation per ACC/AHA guidelines.
| Risk Category | 10-Year Risk | Statin Recommendation | Additional Notes |
|---|---|---|---|
| Low | Below 5% | Lifestyle modifications only | Focus on diet, exercise, smoking cessation |
| Borderline | 5-7.4% | Consider moderate-intensity statin | Discuss with patient, consider risk enhancers |
| Intermediate | 7.5-19.9% | Moderate to high-intensity statin recommended | Coronary artery calcium (CAC) score can refine decision |
| High | 20% or greater | High-intensity statin strongly recommended | Maximize statin therapy, consider adding ezetimibe |
| Very High | Prior ASCVD event | Maximum tolerated statin plus ezetimibe | Consider PCSK9 inhibitor if LDL remains above 70 |
Note: Risk enhancers include family history of premature ASCVD, LDL above 160, metabolic syndrome, chronic kidney disease, and inflammatory conditions. A coronary artery calcium score of 0 may allow deferring statin therapy in borderline and intermediate risk patients. For educational reference only.
Frequently Asked Questions
What do the ASCVD risk categories mean?
Low risk (below 5%), Borderline (5 to 7.4%), Intermediate (7.5 to 19.9%), and High risk (20% or above). These categories guide discussions about preventive therapies, particularly statin use.
When is statin therapy recommended?
AHA/ACC guidelines recommend discussing statin therapy when 10-year ASCVD risk is 7.5% or higher. High-intensity statin therapy is generally recommended when risk exceeds 20%.
What ages is this calculator valid for?
The Pooled Cohort Equations are validated for adults aged 40 to 79. For patients outside this range, different risk assessment approaches are recommended.
What factors does the calculator use?
It uses age, sex, race, total cholesterol, HDL cholesterol, systolic blood pressure, blood pressure treatment status, diabetes status, and current smoking status.
What are risk-enhancing factors?
For borderline or intermediate risk patients, additional factors like family history of premature heart disease, elevated coronary artery calcium (CAC) score, high-sensitivity CRP, or abnormal ankle-brachial index can help guide treatment decisions.
Is this calculator a substitute for medical advice?
No. This tool provides educational risk estimates based on the Pooled Cohort Equations. All treatment decisions, especially regarding statin therapy, should be made through shared decision-making with a qualified healthcare provider.
