Framingham Risk Score (Canada) Calculator

Estimate 10-year cardiovascular disease risk using the Canadian Cardiovascular Society point-based Framingham Risk Score, including the Canadian family history adjustment when it applies.

years

Use ages 30 to 75. CCS routinely recommends risk assessment for many adults aged 40 to 75.

Enter an age from 30 to 75 years.

The published score uses separate male and female point tables.

Select the sex used by the Framingham score.

mmol/L

Enter the HDL-C value from the lipid test.

Enter an HDL-C value greater than 0 and no more than 5 mmol/L.

mmol/L

Enter total cholesterol from the same lipid profile where possible.

Enter total cholesterol greater than 0 and no more than 20 mmol/L.

mmHg

Use the upper number in the blood pressure reading.

Enter systolic blood pressure from 70 to 260 mmHg.

Taking blood pressure treatment?
Current smoker?
Diabetes?

Most adults with diabetes who meet CCS statin-indicated criteria do not need FRS to decide whether a statin is indicated.

Family history of premature cardiovascular disease in a first-degree relative?

For this Canadian modifier, premature CVD means before age 55 in a male first-degree relative or before age 65 in a female first-degree relative.

How the Canadian Framingham Risk Score works

The calculator follows the Canadian Cardiovascular Society Framingham worksheet. It assigns points for age, HDL cholesterol, total cholesterol, systolic blood pressure, blood pressure treatment, smoking, and diabetes. The total point score is then converted to an estimated 10-year risk of a cardiovascular disease event.

For people aged 30 to 59 who do not have diabetes, the Canadian modified FRS doubles the calculated percentage when there is a family history of premature cardiovascular disease in a first-degree relative. The adjustment is not applied outside that age range or when diabetes is present.

Important: This is a risk estimate, not a diagnosis or a guarantee. It is intended for general education and shared decision-making with a qualified health professional.

How to interpret the result

10-year FRS CCS risk category
Less than 10% Low risk
10% to 19.9% Intermediate risk
20% or higher High risk

Risk category alone does not determine treatment. The CCS approach also considers statin-indicated conditions, lipid levels, kidney disease, established atherosclerotic cardiovascular disease, diabetes criteria, and other risk modifiers.

Heart age

Heart age converts the Framingham point total into the age of a person with a comparable risk-factor burden under the Framingham reference approach. It can make long-term risk easier to discuss, especially when 10-year percentage risk is still fairly low because of younger age.

Methodology and assumptions

This implementation uses the sex-specific point tables in the CCS Framingham Risk Score worksheet rather than a different cardiovascular risk model. Cholesterol values are entered in mmol/L and systolic blood pressure in mmHg. The result is rounded to the precision used in the published point conversion table.

The calculator does not attempt to diagnose diabetes, hypertension, chronic kidney disease, familial hypercholesterolemia, or established cardiovascular disease. It also does not replace a full clinical assessment.

Why another calculator might give a different result

Results can differ if another tool uses the continuous Framingham equation instead of the CCS point worksheet, uses a different cardiovascular endpoint, applies different age limits, rounds values differently, or uses another model such as SCORE2 or the pooled cohort equations.

Sources

Methodology is based on the Canadian Cardiovascular Society Framingham Risk Score calculator, the 2024 CCS Framingham Risk Score worksheet, and the 2021 CCS dyslipidemia guideline. The underlying general cardiovascular risk profile was developed from the Framingham Heart Study general CVD risk function.
