Cardiovascular Risk Calculator

Risk Calculator
  • Framingham
    US Data, 10 Year RiskHeart attacks + angina/coronary insufficiency + heart failure + strokes + intermittent claudication
  • QRISK®2-2014
    UK Data, 10 Year RiskHeart attacks + strokes
    US Data, 10 Year RiskCHD death + nonfatal heart attacks
    + fatal/nonfatal strokes
    New Zealand Data, 5 Year RiskHeart attacks + angina + heart failure + strokes/TIAs + peripheral vascular disease



CVD risk is reversed after 5-10 years of no smoking


Systolic Blood Pressure


Enter present blood pressure regardless of treatment

120 mmHg is used for baseline risk

On treatment for BPYesNo

Click YES if taking blood pressure medication

Only applies if SBP is greater than 120 mmHg

Total Cholesterol

Cholesterol should be prior to drug treatment

3 mmol/L is used for baseline risk.
Click to change to mg/dL.

116 mg/dL is used for baseline risk.
Click to change to mmol/L.

HDL Cholesterol

HDL should be prior to drug treatment

1.3 mmol/L is used for baseline risk.

50 mg/dL is used for baseline risk.

Chronic Kidney DiseaseYesNo

CKD status is not part of the risk algorithm but is used for calculating the benefit of certain therapies

Family History of Early CHD


The amount of additional risk (relative increase in risk) conferred from a family member to a patient depends on: (1) how close a relative, (2) age of a relative, (3) number of affected family members.

If mother (< 65 yrs) increase risk 60%

If father (< 55 yrs) increase risk 75%

Relative Benefit:  

Benefit often has nothing to do with the effect on the surrogate marker. At present, you can only select one intervention at a time.
