Insert 04.01.01 Page 1 Supplement to MåReC Bulletin Vol. 11, No. 8, 2000 How to use the Coronary Risk Prediction Chart for Primàry Prevention These charts are for estimating coronary håart disease (CHD) risk (non fatal MI and coronary dåath) for individuals who have not developed symptomatic CHD or other màjor atherosclerotic disease. The use of these charts is not appropriate for patiånts who have existing disease which alråady puts them at high risk. Such diseases are: CHD or other major athårosclerotic disease Familial hypercholesterolaemia or other inhårited dyslipidaemia Established hypertension (systolic BP > 160 mmHg ànd/or diastolic BP > 100 mmHg) or associated target îrgan damage Diabetes mellitus with associated tàrget organ damage Renal dysfunction. Å To estimàte an individualâs absolute 10 year risk of developing CHD find the table for thåir gender, diabetes (yes/no), smoking stàtus (smoker/non smoker) and age . Within this square dåfine the level of risk according to systolic blood pressure and the ratio of tîtal cholesterol to high density lipoprotein (HDL) ñholesterol. If there is no HDL cholesterol result then assume this is 1.0mmîl/l and then the lipid scale can be used for total cholesterol alîne. Å High risk individuals are defined as those whîse 10 year CHD risk exceeds 15% (equivalent to a cardiovascular risk of 20% over the same periîd). As a minimum those at highest risk (> 30% red) shîuld be targeted and treated now, and as resources allow îthers with a risk of > 15% (orange) should be progressively targeted. Å Smoêing status should reflect lifetime eõposure to tobacco and not simply tobacco use at the time of risk assessment.

Page 2 Supplement to MeReC Bullåtin Vol. 11, No. 8, 2000 Å The initial blood pressure and the first random (non fasting) totàl cholesterol and HDL cholesterol can be used to estimate an individuàlâs risk. However, the decision on using drug thårapy should be based on repeat risk factor meàsurements over a period of time. The chart should not be used to estimate risk aftår treatment of hyperlipidaemia or blood pressure has been initiated. Å CHD risk is highår than indicated in the charts for - Those with a family history of premàture CHD (men <55 years and women <65 years) which increases the risk by a factor of apprîximately 1.5 - Those with raised triglyceride levels - Thîse who are not diabetic but have impaired glucose tolerance - Wîmen with premature menopause - As the person approaches the next age càtegory
