Heart Risk Calculator: Your 10-Year Risk (PREVENT)

Calculate your cardiac risk with the American Heart Association’s PREVENT equations, the ASCVD risk calculator used in the 2026 US cholesterol guideline. It runs in your browser: nothing you enter is saved or sent.

This calculator shows the estimate the current ACC/AHA guideline uses: your chance of a heart attack or stroke (atherosclerotic cardiovascular disease, or ASCVD) over the next 10 years, plus total cardiovascular risk including heart failure. It is a learning tool to bring to a conversation with your clinician. Cardio Res-Q does not calculate a PREVENT score as part of its assessments.

You need numbers from a recent check-up: total and HDL cholesterol, your top blood pressure number and your eGFR, a kidney measure printed on most routine blood panels. It is for adults aged 30 to 79 who have never had a heart attack, stroke or heart failure.

Have you had a heart attack, stent, bypass surgery, stroke or heart failure?

15 to 140. On your lab report, often next to creatinine.
Only have creatinine? Estimate your eGFR

Uses the 2021 CKD-EPI creatinine equation, which does not use race, with the age and sex entered above. Your lab’s reported eGFR is preferred when you have it.

Do you take medicine for high blood pressure?
Do you take a statin?
Do you have diabetes?
Do you currently smoke?

What the risk bands mean

The 2026 ACC/AHA cholesterol guideline sorts 10-year PREVENT risk into four bands. The calculator applies them to your 10-year heart attack and stroke estimate.

10-year riskBandWhat it usually means
Under 3%LowHealthy habits are the main focus.
3% to under 5%BorderlineRisk enhancers can shift the picture.
5% to under 10%IntermediateExtra information often helps the treatment discussion.
10% or higherHighA treatment discussion with your clinician is warranted.

PREVENT gives lower numbers than the older Pooled Cohort Equations for most people, so do not compare a PREVENT result with the old 7.5% cut point. See PREVENT vs. the Pooled Cohort Equations.

What this calculator cannot tell you

  • It is not for people with known heart disease. After a heart attack, stent, bypass or stroke, risk is already high and a calculator does not apply.
  • It does not see family history. A parent or sibling with early heart disease raises real risk above the number. See family history of early heart disease.
  • It does not include Lp(a), ApoB or hs-CRP. The guideline advises measuring Lp(a) once in all adults.
  • It does not know whether plaque is present. A coronary calcium score can refine a borderline or intermediate result.
  • It is an average. The percentage describes a group of people with numbers like yours, not a forecast for you.

This page uses the base PREVENT model. The full model can also add HbA1c, a urine albumin test and a zip-code measure, which change the estimate a little for most people. For more on how the equations work, read the PREVENT risk calculator explained. If a borderline or intermediate number leaves you unsure, see what to do next, or look at what the Cardio Res-Q assessments measure.

This calculator is an educational estimate and is not medical advice. It is not for people who already have cardiovascular disease, and it does not replace a conversation with a clinician who knows your history. Do not start, stop or change a medication based on it. If you have chest pain, shortness of breath or other symptoms of a heart attack or stroke, call 911.
