ASCVD Risk Calculator — 10-Year Risk

How this calculator works

Your cardiovascular risk is not a hunch — it's an estimable probability. This calculator applies the Pooled Cohort Equations validated by the American College of Cardiology / American Heart Association on cohorts of over 24,000 followed for years. You get a number and, more importantly, a clear picture of which modifiable factors move it.

Formula and origin

We use the equations published by Goff et al. in Circulation (2014) derived from the ARIC, CHS, CARDIA and Framingham cohorts. There are four coefficient sets (White female, African American female, White male, African American male). The model combines age, sex, race, total cholesterol, HDL, systolic blood pressure, BP treatment, diabetes and current smoking status. The race input is statistical — it reflects the original cohorts, not biology — and there is documented controversy that we address below.

Risk categories (ACC/AHA 2019)

• Low (<5%): Lifestyle focus; reassess in 4-6 years. No statin indication.
• Borderline (5–7.5%): Consider risk enhancers (family history, hsCRP, coronary artery calcium score). Shared decision with your physician.
• Intermediate (7.5–20%): Statin discussion recommended. Coronary calcium score can refine the decision if uncertain.
• High (≥20%): Statin therapy recommended. Aggressive lifestyle and risk-factor modification.

Why we ask about race (and its limitations)

The original equations were derived from predominantly White and African American cohorts, so the race coefficient is a statistical correction, not biological. In Hispanic, Asian, or other populations the PCE can over- or underestimate risk according to a peer-reviewed re-analysis published in Annals of Internal Medicine — see Yadlowsky et al. 2018, Ann Intern Med.

How to lower your risk (evidence-based)

• Quit smoking: Cuts cardiovascular risk ~50% within 1-2 years (immediate impact on the equations). — Arnett 2019, AHA
• Control blood pressure: Lowering systolic by 10 mmHg reduces major CV events ~20%. — Whelton 2017
• Lower LDL by ~30 mg/dL: Relative event reduction ~22% (lifestyle + statin if indicated). — Stone 2014
• Aerobic physical activity: 150 min/week moderate intensity reduces CV mortality ~30%. — Arnett 2019
• Mediterranean or DASH diet: Independent CV risk reduction even with stable LDL. — Arnett 2019
