CVD Risk
Estimate your 10-year cardiovascular disease risk using the Framingham Risk Score. Enter age, cholesterol, blood pressure, smoking, and diabetes for personalized results.
About This Calculator
The CVD Risk Calculator estimates your 10-year probability of developing cardiovascular disease using the validated Framingham General Cardiovascular Disease Risk Score. Developed from the landmark Framingham Heart Study (D'Agostino et al., Circulation 2008), this tool is designed for adults aged 30–74 years without prior cardiovascular disease who want to understand their heart health risk profile.
The calculator uses eight clinical parameters — age, sex, total cholesterol, HDL cholesterol, systolic blood pressure, hypertension treatment status, smoking status, and diabetes status — to compute your personalized 10-year CVD risk percentage. The Framingham model uses Cox proportional hazards regression to generate risk estimates that account for the complex interactions between these cardiovascular risk factors.
Your results include a 10-year risk percentage, a risk category (low, borderline, intermediate, or high), your estimated heart vascular age, and a risk ratio comparing your risk to someone of the same age with optimal risk factors. The accompanying chart visualizes your risk category and how your risk changes with advancing age.
Regional Notes
India: The Framingham model may underestimate risk in South Asian populations. The WHO/ISH risk prediction charts or the INTERHEART Risk Score are sometimes preferred. Indian adults often develop CVD 5-10 years earlier than Western populations, so even a "borderline" Framingham result warrants attention.
United States: The ACC/AHA Pooled Cohort Equations (2013) are the standard for ASCVD risk assessment in US clinical practice, though Framingham remains widely used in research and as a historical reference. The American Heart Association recommends risk assessment starting at age 40.
United Kingdom: The NHS uses QRISK3 (which includes ethnicity, social deprivation, and other factors) for the NHS Health Check program. Framingham-based tools are considered somewhat outdated in UK practice, but the underlying principles remain valid for educational use.
Frequently Asked Questions
How is 10-year CVD risk calculated?
The CVD risk calculator uses the Framingham General Cardiovascular Disease Risk Score (D'Agostino et al., Circulation 2008). It calculates 10-year risk using the Cox proportional hazards model with predictors including age, sex, total cholesterol, HDL cholesterol, systolic blood pressure, hypertension treatment, smoking status, and diabetes status. The model outputs a risk percentage representing the probability of developing a cardiovascular event within 10 years.
Who should use this CVD risk calculator?
This calculator is validated for adults aged 30 to 74 years without prior cardiovascular disease. It is intended for primary prevention screening in outpatient settings. If you have already been diagnosed with heart disease, stroke, peripheral artery disease, or heart failure, consult your cardiologist for condition-specific risk assessment.
What does the Framingham Risk Score measure?
The Framingham Risk Score estimates the 10-year risk of developing cardiovascular disease, including coronary heart disease (heart attack), cerebrovascular disease (stroke), peripheral vascular disease, and heart failure. It was developed from the Framingham Heart Study cohort of 8,491 participants and has been validated across multiple populations worldwide.
What is a normal 10-year CVD risk percentage?
A 10-year CVD risk below 5% is considered low risk, 5 to 7.4% is borderline risk, 7.5 to 19.9% is intermediate risk, and 20% or above is high risk. Risk interpretation should always be done by a healthcare professional who can consider additional factors like family history, lifestyle, and other biomarkers.
Can I use this calculator if I am under 30 or over 74?
The Framingham CVD risk model was validated for adults aged 30 to 74 years. For individuals under 30, the absolute risk is very low and other risk assessment tools may be more appropriate. For those over 74, the SCORE-OP or similar tools are recommended for older populations. Always consult your healthcare provider for personalized risk assessment.
What is heart vascular age?
Heart vascular age is a derived metric that compares your calculated CVD risk to the average risk of someone your age with optimal risk factors. If your heart vascular age is higher than your chronological age, it indicates that your cardiovascular risk profile is worse than average for your age group, serving as a motivating tool for lifestyle modification.
Do different countries have different CVD risk guidelines?
Yes, different countries use different risk assessment tools. In the US, the ACC/AHA Pooled Cohort Equations are commonly used alongside Framingham. In the UK, QRISK3 is the recommended tool, and the NHS uses it for the NHS Health Check program. In India, the WHO/ISH risk prediction charts are often used. This calculator uses the Framingham model for global reference.
Can I rely on this calculator for medical decisions?
No. This calculator is for educational and reference purposes only. It is not a substitute for professional medical advice, diagnosis, or treatment. The Framingham model may over- or under-estimate risk in certain ethnic groups. Always discuss your cardiovascular risk with a qualified healthcare provider who can perform a comprehensive assessment.
