As an illustration for using the score sheets, consider a 55 year old man with a total cholesterol of 250 mg/dL, HDL cholesterol of 39 mg/dL, blood pressure of 146/88, diabetic and a non-smoker.
Use the Total Cholesterol Score Sheet when total cholesterol and HDL cholesterol are available. Use the LDL Cholesterol Score Sheet when LDL cholesterol and HDL cholesterol are available.
Step | Factor | Points |
1 | Age = 55 years | 4 |
2 | *Total cholesterol = 250 mg/dL | 2 |
3 | HDL cholesterol = 39 mg/dL | 1 |
4 | Blood pressure = 146/88 mm Hg | 2 |
5 | Diabetic = yes | 2 |
6 | Cigarette smoker = no | 0 |
7 | Point Total | 11 |
8 | Estimated 10 Year CHD Risk | 31% |
9 | Low 10 Year CHD Risk | 7% |
Relative Risk (step 8 divided by step 9) | 31/7 = 4.4 | |
*Use of the LDL cholesterol approach in the scoresheets is appropriate when fasting LDL cholesterol estimates are available. The approach is analogous to that shown for total cholesterol categories. |
The average and low risk of CHD over 10 years for a 55 year old man are 16% and 7% respectively . The average risk was derived from the experience of Framingham men and women, using their average risk factor levels to provide the estimates. The low risk was calculated using the following factors:
