Framingham Risk Calculator — 10-Year CVD, Hard CHD & Stroke
One input set, three classic Framingham endpoints: General CVD 10-year risk (D'Agostino 2008), hard CHD 10-year risk (ATP III / Wilson 1998) and stroke 10-year risk (Framingham Stroke Risk Profile, 1991). Each endpoint shows its point breakdown, 10-year risk %, risk category and an illustrative heart age — side by side, so you can compare them.

Your numbers
Cholesterol — used by the CVD and hard-CHD endpoints
Stroke-specific — only used by the stroke endpoint
🫀 General CVD — 10-year risk
D'Agostino et al. 2008 — any cardiovascular event (CHD, stroke, claudication, heart failure). Validated ages 30–74.
–10-year risk
–
Points per factor come from the published sex-specific score sheets; the total maps to risk via the published points→risk table (discrete lookup).
❤️ Hard CHD — 10-year risk
ATP III Framingham score (Wilson 1998) — myocardial infarction or coronary death. Validated ages 20–79.
–10-year risk
–
ATP III treats diabetes as a CHD risk equivalent — it is not counted in the points above. If you have diabetes, discuss CHD prevention with your clinician regardless of this number.
🧠 Stroke — 10-year risk
Framingham Stroke Risk Profile (Wolf et al., Stroke 1991) — incident stroke. Developed for adults 55+.
–10-year risk
–
The stroke profile was developed for adults aged 55 and older — results below 55 are outside its validated range.
Compare the three endpoints
Same person, same inputs — different outcomes, because each endpoint was built from a different Framingham analysis.
Worked examples
Load a preset profile to see how the three endpoints respond. Anchors 1–2 are the published worked examples from D'Agostino 2008.
Paper case: woman, 61 D'Agostino 2008 worked example — 13 pts → 10.0% CVD.
Paper case: man, 53 D'Agostino 2008 worked example — 13 pts → 15.6% CVD.
Optimal profile, 50 All factors ideal — heart age ≈ chronological age.
Scope boundary — what this tool is (and isn't)
This tool = Framingham multi-endpoint hub. Three published Framingham point-score models (General CVD + hard CHD + stroke) computed from one input set, with per-endpoint breakdowns, comparison and heart age.
Need a quick single CVD estimate? Try our CVD risk calculator — one endpoint, fewer inputs, same D'Agostino 2008 model.
Want the modern guideline model? The 2013 ACC/AHA Pooled Cohort Equations (ASCVD) are a different, newer model — see the FAQ below.
This tool does not diagnose, does not estimate lifetime risk, and does not apply to people who already had a heart attack or stroke (secondary prevention is a clinical decision).
Methodology & primary sources
How it works: each risk factor is converted to integer points using the published sex-specific score sheet → points are summed → the total is mapped to a 10-year risk % through the published points→risk lookup table (a discrete table, not a smooth formula). Categories: low <10%, intermediate 10–20%, high >20%.
(a) General CVD: D'Agostino RB et al. "General Cardiovascular Risk Profile for Use in Primary Care: The Framingham Heart Study." Circulation 2008;117:743–753 — laboratory (lipid) point sheets.
(b) Hard CHD: Wilson PWF et al. Circulation 1998;97:1837–1847, as adopted by the NCEP Adult Treatment Panel III (NIH Publication No. 01-3305, May 2001).
(c) Stroke: Wolf PA, D’Agostino RB, Belanger AJ, Kannel WB. “Probability of stroke: a risk profile from the Framingham Study.” Stroke 1991 — the classic Framingham Stroke Risk Profile (includes ECG-LVH). Note: a revised profile was published by Dufouil et al., Stroke 2017; this tool implements the 1991 profile.
Heart age is an illustrative communication aid (per D'Agostino 2008): the age at which a person with the same predicted points but all other factors at optimal levels would sit. It is not a published sheet value; "90+"/"95+" means the risk exceeds what age alone explains at the top of the scale.
Frequently asked questions
What is the Framingham risk score?
The Framingham risk score is a set of point-based tools developed from the Framingham Heart Study, a long-running cardiovascular research project started in 1948. Each tool converts risk factors such as age, cholesterol, blood pressure, smoking and diabetes into points, then maps the point total to a 10-year probability of a cardiovascular event. This calculator implements three of those published tools in one place.
What are the three endpoints in this calculator?
General CVD estimates the 10-year risk of any cardiovascular event — coronary heart disease, stroke, intermittent claudication or heart failure (D'Agostino 2008). Hard CHD estimates the 10-year risk of myocardial infarction (heart attack) or coronary death only (ATP III / Wilson 1998). Stroke estimates the 10-year risk of incident stroke using the classic Framingham Stroke Risk Profile (Wolf et al., Stroke 1991). The same inputs can give different numbers because each endpoint was built from a different analysis.
How is my score calculated?
Each risk factor is converted to integer points using the published sex-specific score sheet for that endpoint. The points are added up, and the total is looked up in the published points-to-risk table — a discrete table, not a smooth formula. You can see every factor's contribution in the per-endpoint breakdown tables above.
What do the low, intermediate and high categories mean?
Following the common clinical convention: low means a 10-year risk below 10%, intermediate means 10–20%, and high means above 20%. The category describes a statistical risk band from population data — it is not a diagnosis, and it does not mean an event will or will not happen to you personally.
What is “heart age”?
Heart age is a risk-communication aid from the Framingham researchers: the age at which a person with the same risk points but all other factors at optimal levels would sit. If your heart age is above your actual age, your modifiable factors are adding risk beyond your years. It is illustrative, not a published sheet value — and a capped value such as 90+ means your risk exceeds what age alone can explain at the top of the scale.
Framingham vs ASCVD — what is the difference?
The Framingham scores are the classic point-sheet models from the Framingham Heart Study cohorts. The ASCVD (Pooled Cohort Equations, 2013 ACC/AHA) is a newer model recommended by current US guidelines; it estimates atherosclerotic cardiovascular disease risk using a continuous Cox equation rather than point sheets and was derived from more diverse, contemporary cohorts. They can disagree — that is normal, because they are different models, not different measurements of one truth.
Why does the stroke score ask about atrial fibrillation and LVH?
The Framingham Stroke Risk Profile was built specifically for stroke, and its strongest single predictors include atrial fibrillation (an irregular heartbeat that can form clots) and left ventricular hypertrophy on ECG. These factors matter far more for stroke than for coronary risk, which is why the stroke endpoint needs inputs the other two do not use.
Why is diabetes not counted in the hard CHD score?
The ATP III hard-CHD point sheet has no diabetes points because the guideline treats diabetes as a CHD risk equivalent — meaning diabetes alone is considered to confer high coronary risk, handled outside the point system. The calculator shows a reminder of this whenever the hard CHD result is displayed.
What ages are these scores validated for?
General CVD was validated for ages 30–74, hard CHD for ages 20–79, and the stroke profile was developed for adults aged 55 and older. Results outside these ranges are extrapolations of the published tables and should be treated with extra caution.
How accurate are Framingham scores today?
Framingham models were derived from a predominantly white, mid-20th-century US population, and contemporary validation studies show they can overestimate risk in modern populations with better prevention and treatment — a revised stroke profile was published in 2017, while this tool implements the widely used 1991 profile. Treat every number here as an educational estimate for discussion with a clinician, not a personal prediction.
Is this medical advice?
No. This is an educational estimate — not medical advice. Risk scores guide discussion with a clinician; they do not diagnose. Never start, stop or change any medication based on a calculator result.
Need a quick single CVD estimate instead?
Try our CVD risk calculator — it computes just the General CVD endpoint with fewer inputs, using the same D'Agostino 2008 model. This Framingham hub is for comparing all three endpoints side by side.
