CHD Risk Calculator
What are the odds of a coronary event in the next ten years? Enter your numbers and see your 10-year risk category and the factors driving it.
CHD risk is the probability of a coronary heart disease event such as a heart attack within ten years, estimated from age, cholesterol, blood pressure, smoking, and diabetes using the Framingham risk model. Results are screening estimates, not diagnoses — confirm with a clinician before acting on them.
<10% = low risk.
10–20% = intermediate.
≥20% = high, act now.

Your 10-Year CHD Risk
What Is CHD Risk?
Coronary heart disease (CHD) risk is the probability of a coronary event, heart attack or coronary death, within ten years.
This calculator applies a Framingham-style points model, the ancestor of modern risk scores. Clinical practice today uses the ASCVD Pooled Cohort Equations or QRISK, which add ethnicity, kidney function, and family history.
How It Is Calculated
Framingham points: age + total cholesterol + HDL + systolic BP + smoking + diabetes
Example: Example: 50-year-old male smoker, SBP 140, TC 240, HDL 40 → ≈ 20% 10-year risk
10-year CHD risk categories
| Risk | Category | Action |
|---|---|---|
| < 10% | Low | Healthy lifestyle |
| 10–20% | Intermediate | Lifestyle + re-check |
| ≥ 20% | High | Clinical prevention plan |
Limitations
- Educational estimate, not a clinical score.
- Doesn't include family history, ethnicity, inflammation, or kidney disease.
- Model applies to ages 20–79 without prior cardiovascular disease.
- See a clinician for a formal assessment if risk factors are present.

CHD Risk FAQ
What is a good 10-year heart risk?
Below 10% is considered low risk. Between 10% and 20% is intermediate, and 20% or above is high and warrants a prevention plan.
What factors drive CHD risk most?
Age, smoking, systolic blood pressure, and cholesterol carry the most weight, with diabetes and low HDL adding further risk.
Can I lower my 10-year risk?
Yes, stopping smoking, lowering blood pressure and LDL cholesterol, and treating diabetes reduce risk measurably within a few years.
Is this the same as the ASCVD calculator?
No. This is a Framingham-style educational model. The ASCVD Pooled Cohort Equations are the current clinical standard in the U.S.
Important disclaimer: Results are educational estimates, not a substitute for professional medical advice. Discuss your numbers with a clinician before acting on them.
