The calculator estimates the risk of having a heart attack or dying from heart disease in the next 10 years. The tool is designed for people who are older than 20 and who do not have diabetes or heart disease.

This information is provided for education purposes only and is not intended to replace the medical advice of a doctor or health care provider.

Treatment targets are based on the Canadian Cardiovascular Society 2009 guidelines.

To calculate a patient's score use this tool: Reynolds risk calculator.

Score  Risk  Consider treatment if  Treatment target 

< 10

 Low

LDL-C ≥ 5.0 mmol/L

≥ 50% decrease in LDL-C

 10 - 19

Moderate
(Framingham risk score only)

LDL-C > 3.5 mmol/L or TC/HDL-C > 5.0 or

hs-CRP > 2 mg/L in
men > 50 years old
or
women > 60 years old

LDL-C < 2.0 mmol/L or ≥ 50% decrease in LDL-C or apoB < 0.80 g/L.

Discussion with the patient of relative and absolute benefit of therapy is advised.

 ≥ 20

High
(Reynolds or Framingham risk score)

Patients with high score.

Patients with one or more of the following:
- coronary artery disease or
- peripheral vascular disease or
- atherosclerosis.

Most patients with diabetes.

LDL-C < 2.0 mmol/L or ≥ 50% decrease in LDL-C or apoB < 0.80 g/L.

 

Low risk = Less than 10% risk of a heart attack or dying from heart disease in the next 10 years.

Moderate risk = 10 to 20% risk of a heart attack or dying from heart disease in the next 10 years.

High risk = Greater than 20% risk of a heart attack or dying from heart disease in the next 10 years.
