About This Calculator
The ASCVD (Atherosclerotic Cardiovascular Disease) Risk Calculator estimates a patient's 10-year risk of a first atherosclerotic cardiovascular event (heart attack or stroke) using the Pooled Cohort Equations from the 2013 ACC/AHA guidelines. It is validated for adults aged 40ā79 without prior ASCVD events. The risk estimate helps guide discussions about statin therapy and lifestyle modifications.

Frequently Asked Questions
What is the ASCVD risk score?
The ASCVD risk score estimates the 10-year probability of a first atherosclerotic cardiovascular event (heart attack or stroke). It uses the Pooled Cohort Equations developed by the AHA/ACC and considers age, sex, race, cholesterol, blood pressure, diabetes, and smoking status.
What ASCVD risk level requires statin therapy?
Per 2018 AHA/ACC guidelines: risk <5% is low (lifestyle modifications), 5ā7.5% is borderline (consider risk enhancers), 7.5ā20% is intermediate (moderate-intensity statin), and ā„20% is high (high-intensity statin recommended).
What are ASCVD risk-enhancing factors?
Risk enhancers include family history of premature ASCVD, LDL-C ā„160 mg/dL, metabolic syndrome, chronic kidney disease, chronic inflammatory conditions, South Asian ancestry, and elevated biomarkers (hsCRP ā„2, Lp(a) ā„50, apoB ā„130).
Does the ASCVD calculator apply to patients over 79?
The Pooled Cohort Equations were validated for ages 40ā79. Risk estimates for patients outside this range are less reliable. For older adults, shared decision-making with consideration of life expectancy and comorbidities is recommended.
