Understanding the Framingham Risk Score
What is the Framingham Study?
The Framingham Heart Study began in 1948 with 5,209 participants from Framingham, Massachusetts. This landmark 72-year study identified major cardiovascular risk factors and created the foundation for modern cardiovascular risk assessment.
What Does the Score Mean?
The Framingham Risk Score estimates your 10-year probability of developing coronary heart disease, including heart attack and coronary death. It's based on age, gender, blood pressure, cholesterol levels, smoking status, and diabetes.
Who Should Use This Calculator?
- •Adults aged 30-79 years
- •No history of heart disease or stroke
- •People seeking cardiovascular risk assessment
Mathematical Formula
Men:
Score = 52.01×ln(age) + 20.01×ln(cholesterol) - 0.91×ln(HDL) + 1.31×ln(BP) + 0.24×treatment + 12.1×smoker - 4.61×ln(age)×ln(cholesterol) - 2.84×ln(age)×smoker - 2.93×ln(age)² - 172.30
Women:
Score = 31.76×ln(age) + 22.47×ln(cholesterol) - 1.19×ln(HDL) + 2.55×ln(BP) + 0.42×treatment + 13.08×smoker - 5.06×ln(age)×ln(cholesterol) - 3×ln(age)×smoker - 146.59
10-Year Risk: 1 - (baseline_survival)^exp(score)
Baseline survival: 0.9402 (men), 0.98767 (women)
Important: This calculator estimates risk for the general population. Individual risk may vary based on family history, ethnicity, and other factors not included in the original study.
