Coronary Risk
Prediction Charts for Primary Prevention
These charts are for estimating the risk of CHD for individuals who have not developed symptoms of CHD or other major atherosclerotic disease. These charts are not appropriate for patients who have existing disease that already puts them at high risk. Such diseases are:
- CHD or major atherosclerotic disease
- Familial hypercholesterolaemia or other inherited disease
- Established hypertension (systolic BP >160 mm Hg or diastolic >100 mm Hg) or associated target organ damage
- Diabetes mellitus with associated target organ damage
- Renal dysfunction
Risk chart for patients with no diabetes
Risk chart for patients with diabetes
To estimate an individuals absolute 10 year risk of developing CHD, use the appropriate chart for diabetes or no diabetes and find the table for their sex, smoking status (smoker/non-smoker), and age. Within this square define the level of risk according to systolic blood pressure and the ratio of total cholesterol to HDL cholesterol.
High risk individuals are defined as those whose 10 year risk of CHD exceeds 15% (equivalent to a cardiovascular risk of 20% over the same period). As a minimum, those at highest risk (>30%; red) should be targeted and treated now, and as resources allow others with a risk of >15% (orange) should be progressively targeted.
