Framingham Risk Score Calculator
Calculate your 10-year cardiovascular disease risk using the Framingham Heart Study model. This validated tool uses age, cholesterol, blood pressure, smoking, and diabetes status to estimate coronary heart disease probability.

Why: The Framingham Risk Score is the gold standard for primary prevention cardiovascular risk assessment, guiding statin therapy and lifestyle intervention decisions for millions of patients.
How: Enter age, gender, total cholesterol, HDL cholesterol, systolic BP, BP treatment status, smoking status, and diabetes status. The Cox regression model produces a 10-year CHD probability.

The Framingham Heart Study
The Framingham Risk Score derives from the landmark Framingham Heart Study, ongoing since 1948. It predicts 10-year risk of coronary heart disease, stroke, and peripheral arterial disease using age, sex, cholesterol, blood pressure, smoking, and diabetes.
Risk Categories
Low Risk (<10%)
Lifestyle modifications and routine monitoring.
Borderline (5-7.4%)
Enhanced lifestyle counseling, consider risk enhancers.
Intermediate (7.5-19.9%)
Consider statin therapy, lifestyle modifications.
High (≥20%)
High-intensity statin, aggressive risk factor modification.
Modifiable Risk Factors
- Total and LDL cholesterol (diet, statins)
- HDL cholesterol (exercise, weight loss)
- Blood pressure (DASH diet, medications)
- Smoking cessation
- Diabetes management
- Weight and physical activity
ASCVD Pooled Cohort Equations
The AHA/ACC 2018 guidelines use pooled cohort equations with race-specific coefficients. ASCVD includes myocardial infarction, stroke, and cardiovascular death. Used for statin eligibility decisions.
Reynolds Risk Score
Reynolds adds high-sensitivity CRP and family history. Particularly useful in intermediate-risk patients where Framingham may under- or over-estimate. Improves reclassification in ~15-20% of cases.
Statin Eligibility
Per AHA/ACC 2018: High-intensity statin for ≥20% risk; moderate-intensity for 7.5-19.9%; consider for 5-7.4% with risk enhancers (family history, LDL >160, metabolic syndrome, CKD).
Heart Age
Heart age estimates vascular age from risk factors. If higher than chronological age, it reflects accelerated atherosclerosis. A useful motivator for lifestyle change and medication adherence.

FAQ
What is the Framingham Risk Score?
A validated tool predicting 10-year cardiovascular disease risk using age, cholesterol, blood pressure, smoking, and diabetes. Based on the landmark Framingham Heart Study since 1948. Used for primary prevention and statin eligibility decisions.
What are the Framingham risk categories?
Low risk: <10% 10-year CVD probability. Intermediate: 10-19%. High risk: ≥20%. Higher categories warrant more aggressive prevention including statin therapy per ACC/AHA guidelines.
What is heart age?
Estimated vascular age based on risk factors; may be higher than chronological age with poor cardiovascular health. A motivator for lifestyle change and medication adherence.
What are statin therapy thresholds?
High-intensity statin for ≥20% risk; moderate-intensity for 7.5-19.9%; consider for 5-7.4% with risk enhancers per AHA/ACC 2018 guidelines.
What are the limitations of the Framingham score?
May under- or over-estimate in some populations. Does not include family history, CRP, or coronary calcium. Best used with clinical judgment and shared decision-making.
What are modifiable risk factors?
Total and LDL cholesterol (diet, statins), HDL (exercise, weight loss), blood pressure (DASH diet, medications), smoking cessation, diabetes management, and physical activity.
