Framingham Risk Score Calculator

Framingham Risk Score Calculator for Cardiology. The main result is the point total with the original risk label. Lower values remain <1% and upper values >=30%, not invented exact probabilities.

For shared guidance on choosing a tool and documenting results, read the clinical calculator workflow.

How this calculator works

This is the NHLBI 2001 ATP III sex-specific point model for ten-year hard coronary heart disease. It adds age, age-dependent cholesterol and smoking points, HDL points and treated/untreated pressure points. Decimal ages use completed years and laboratory/pressure intervals are continuous.

When to use this calculator

Historical point-model comparison and education, not the 2008 general-CVD equation or a contemporary lipid-treatment engine.

Inputs used

  • Age (years)
  • Sex coefficient in the source model
  • Total cholesterol (mmol/L; US mg/dL)
  • HDL cholesterol (mmol/L; US mg/dL)
  • Systolic pressure (mmHg)
  • Current smoking
  • Current antihypertensive treatment

Clinical interpretation

The main result is the point total with the original risk label. Lower values remain <1% and upper values >=30%, not invented exact probabilities.

Worked example

A 55-year-old male-coefficient case with cholesterol 220 mg/dL, HDL 40, untreated BP 140 and smoking gives 16 points and a historical 25% estimate. Male total 0 or female total 9 maps to 1%, not zero.

Limitations and safety notes

The original ATP III context handles known CHD and diabetes separately. Transportability and current treatment thresholds need current guidance; historical point tables do not represent an individualized guarantee.

Frequently asked questions

Why show >=30% instead of exactly 30%?

The published upper category is bounded. An exact 30% would imply more precision than the source provides.

What does this result leave unresolved?

The original ATP III context handles known CHD and diabetes separately. Transportability and current treatment thresholds need current guidance; historical point tables do not represent an individualized guarantee.

  • Prefer original validation studies for scoring systems and prediction tools.
  • Use current specialty society guidance, transplant allocation policy, public health guidance, or regulator resources when they govern clinical use.
  • Include limitations and safety notes when a calculator is population-specific, context-dependent, or unsuitable as a standalone decision tool.
