ASCVD Calculator
The ASCVD Risk Calculator estimates 10-year risk of atherosclerotic cardiovascular disease events using the Pooled Cohort Equations. It guides shared decision-making for statin therapy initiation.

What the ASCVD Risk Means
The 10-year ASCVD risk represents the probability of having a cardiovascular event (heart attack or stroke) in the next 10 years. Risk categories: Low (<5%), Borderline (5-7.5%), Intermediate (7.5-20%), High (≥20%). These thresholds guide statin therapy and lifestyle intervention decisions.
When to Use This Calculator
- Primary prevention statin therapy decisions
- Patient counseling on cardiovascular risk
- Risk-benefit discussion for aspirin therapy
- Motivating lifestyle modifications
Frequently Asked Questions
What risk threshold warrants statin therapy?
ACC/AHA guidelines suggest considering moderate-intensity statins for 10-year risk of 7.5-20%, and high-intensity statins for risk ≥20%. For 5-7.5%, additional risk enhancers help guide the decision.
What are the limitations of the ASCVD calculator?
The calculator may overestimate risk in some populations. It does not account for family history, inflammatory markers (hsCRP), coronary artery calcium scores, or other emerging risk factors.
