What is Framingham Risk Score Calculator (10-year CHD)?
The Framingham Risk Score estimates a patient's 10-year probability of developing hard coronary heart disease events — myocardial infarction or coronary death. Derived from the Framingham Heart Study cohort and adopted by the National Cholesterol Education Program Adult Treatment Panel III in 2001, it uses six factors: age, sex, total cholesterol, HDL cholesterol, systolic blood pressure (treated or untreated), and smoking status. Risk is categorized as low (<10%), intermediate (10–20%), or high (>20%) over 10 years, guiding intensity of lipid-lowering and antihypertensive therapy. It applies to adults 20–79 without known cardiovascular disease or diabetes.
How to use
- Select sex and enter age, total cholesterol, and HDL.
- Enter systolic BP, mark whether it is treated, and whether the patient smokes.

Frequently asked questions
What is the Framingham Risk Score?
This calculator uses the NCEP ATP III point system to estimate 10-year risk of hard coronary heart disease (myocardial infarction and coronary death).
How is the risk categorised?
ATP III categories: low (< 10%), intermediate (10–20%), and high (> 20%) 10-year hard-CHD risk.
Who should not use this?
It is for primary prevention in adults 20–79 without known CHD or CHD-equivalents (diabetes, established atherosclerotic disease are treated as high risk regardless).
Framingham vs pooled cohort equations?
The ACC/AHA pooled cohort equations estimate 10-year ASCVD (including stroke) and are now widely used; the ATP III Framingham score remains common for hard-CHD estimation.
