Framingham Risk Score Calculator
Estimate your 10-year risk of developing cardiovascular disease using the Framingham Risk Score algorithm based on key risk factors.
How to Use This Calculator
- Enter your age and select your gender
- Input your total cholesterol and HDL cholesterol levels from recent blood tests
- Enter your systolic blood pressure and indicate if you're on BP medication
- Check the boxes if you're a current smoker or have diabetes
- Click Calculate to see your 10-year cardiovascular disease risk
Formula Used
Risk Score = β0 + Σ(βi × Xi)
Where:
- β0 = Baseline value (different for men and women)
- βi = Coefficient for each risk factor
- Xi = Value of each risk factor (age, cholesterol, blood pressure, etc.)
- 10-Year Risk = 1 - (Baseline Survival)^exp(Risk Score - Mean Risk Score)
Example Calculation
Real-World Scenario:
A 55-year-old male wants to assess his cardiovascular risk before starting an exercise program.
Given:
- Age = 55 years
- Gender = Male
- Total Cholesterol = 220 mg/dL
- HDL Cholesterol = 40 mg/dL
- Systolic BP = 140 mmHg
- BP Treatment = Yes
- Smoker = No
- Diabetes = No
Calculation:
Using the Framingham algorithm with the male coefficients for each risk factor, the risk score is calculated and converted to a percentage.
Result: 16% 10-year risk of cardiovascular disease, classified as high risk
