Based on Framingham 2008 · Cholesterol and BMI-based models
Explore estimated 10-year general cardiovascular disease risk and express that risk as a heart/vascular age. This reference tool is for adults aged 30–74 without existing cardiovascular disease.
This is a different model from Korea’s national health-screening cardiovascular age assessment. It does not diagnose disease, prescribe treatment or predict lifespan.
Reproducible checks with fictional inputs
Checked: 1 November 2026 (KST). No real patient data were used. Expected values were calculated independently from the published continuous equations and compared with this page’s calculation code. Expected risk and age below are unrounded values; the screen follows the existing display policy.
Unrounded equivalent ages in this table are mathematical verification values only. Values beyond display bounds, including ages over 85, must not be interpreted as biological ages or clinically validated predictions. Expected values come from our independent implementation of the published equations, not from running the official calculator for every case.

Boundary and error checks
- Each language’s calculation code was checked against 31 numerical cases covering both models, both sex-specific equations, treatment, smoking and diabetes. Absolute differences were below 10⁻¹² in risk probability and 10⁻⁸ years in equivalent age.
- Each language also passed 51 input, conversion and display checks. Ages 30/74 were accepted; ages 29/75 and fractional ages were rejected. Missing required entries, prior/uncertain CVD, out-of-range BP/lipids/BMI and total cholesterol ≤ HDL were rejected.
- We checked mmol/L boundary inputs and round-trip conversion of 100, 180 and 405 mg/dL using 38.67. Changing the unit while keeping the same number does not represent the same input.
- The over-30% and over-85 labels were checked before rounding, along with one-decimal risk and whole-year age display. Allowed input ranges are not normal ranges or treatment targets.
These are numerical implementation checks, not clinical accuracy testing, external validation in Korean populations, independent medical review or Framingham endorsement. Read the existing eligibility and limitations below.

Who is this for?
The Framingham 2008 model was developed using people aged 30–74 who had no cardiovascular disease at baseline. Do not use this tool to assess your personal risk if you are outside this age range or have a history of heart attack, angina, stroke, transient ischaemic attack, heart failure or peripheral artery disease. Ask a clinician if you are unsure whether the model applies.
The original model uses separate equations for men and women. If it is unclear which equation applies to you, do not guess and treat the output as a personal assessment.
Choose a model
Cholesterol model: uses measured total cholesterol and HDL cholesterol.
BMI-based model: uses BMI in place of lipid inputs in a separate equation. It may provide a reference estimate when lipid results are unavailable, but it does not replace lipid testing or estimate your cholesterol level.
Both models require age, the model’s sex category, systolic blood pressure, blood-pressure medication use, current smoking status and diabetes status. Do not substitute an assumed normal reading for an unknown blood pressure.
Check your inputs
- Systolic blood pressure is the higher of the two blood-pressure readings, in mmHg.
- Select blood-pressure treatment if you take it, even when your current reading is controlled.
- Use total cholesterol and HDL, not LDL or triglycerides.
- Check the units supported by the calculator alongside your original report.
- Do not treat an unknown answer as “no.” Keep your test date, measurement conditions and medication list nearby.
What does heart/vascular age mean?
It is the age at which a same-sex reference profile would have the same estimated risk. It does not measure biological ageing or the years you have left to live. Read the 10-year risk alongside the age.
The reference profile is a calculation convention, not your blood-pressure, cholesterol or weight treatment target.
The comparison uses untreated systolic blood pressure of 125 mmHg, no current smoking and no diabetes. The cholesterol model uses total cholesterol of 180 mg/dL and HDL of 45 mg/dL; the BMI-based model uses BMI of 22.5 kg/m². These values are not personal treatment goals.
Results beyond the display limits appear as “Over 85 years” or “Over 30%.” These labels do not mean the exact calculated result is 85 or 30%. Your actual input age must be 30–74; the output is a separate comparison age.
A comparison age of 75 or above extrapolates beyond the study’s actual-age range. It does not establish validated prediction accuracy in that older age group.
What risk is included?
General CVD includes coronary disease, stroke or transient ischaemic attack, peripheral artery disease and heart failure. It is broader than some ASCVD definitions and is not a cardiovascular death probability. Percentages from different risk models are not interchangeable.
Limits for people in Korea
This is a reference estimate from a model developed in the US Framingham study. It should not be assumed to provide a validated individual prediction for a person in Korea. It may overestimate or underestimate risk, and it does not capture every relevant aspect of health.
Questions about your result
Is this the same as Korea’s screening “심뇌혈관 나이”?
No. This tool uses Framingham 2008. Its model, comparison profile and application differ from the national screening assessment. Do not use it to reproduce or correct an official screening result.
How does this differ from K-CVD?
The study populations, equations and outcomes differ. Read each tool’s scope separately; do not convert, combine or average their results.
Why do the cholesterol and BMI-based results differ?
They use different inputs and equations. Keep the model name with the result rather than choosing whichever number looks better.
Does a lower age mean I can skip care?
No. It does not rule out disease or explain current symptoms. A higher age also does not establish a diagnosis. Discuss the inputs, your individual risk factors and next steps with a clinician. Do not change medication from this result alone.
