NON-LABORATORY BASED RISK SCREENING
BMI-BASED RISK ASSESSMENT
- Measure body mass index (BMI): BMI=weight (kg)/[height (m) x height (m)]
- Measure blood pressure.
- Calculate 10-year risk of a cardiovascular event using the BMI-based CVD risk tool below.
- Use the patient’s sex, age, BMI, systolic BP and smoking status to work out what colour block they fall into
- Explain to the patient what his/her risk of heart attack or stroke might be over the next 10 years

LABORATORY BASED RISK SCREENING
FRAMINGHAM RISK SCORE (CHOLESTEROL-BASED)
- To derive the absolute risk as a percentage of patients who will have a cardiovascular event (i.e. death, myocardial infarction or stroke) over 10 years, add the points for each risk category (Section A). The risk associated with the total points is then derived from Section B.
- Calculation of CVD risk using the table:
- A risk of MI > 20% in 10 years equates to ≥ 15 points for men, and ≥ 18 points for women. It is important to score each patient individually, as there are many combinations of risk factors that can add up to those total points.
- For example:
A male patient > 60 yrs old with systolic BP > 140 mmHg on treatment would score:- 11 points for his sex and age
- 4 points for his on-treatment BP
- Total: 15 points
- A male patient > 50 yrs old with systolic BP > 130 mmHg on treatment who is a smoker would score:
- 8 points for his sex and age
- 3 points for his on-treatment BP
- 4 points for his smoking status
- Total: 15 points
- A female patient > 70 yrs old with systolic BP > 160 mmHg on treatment would score:
- 11 points for her sex and age
- 7 points for her on-treatment BP
- Total: 18 points
