The cardiovascular risk chart is a
simple and objective way of assessing the likelihood of experiencing
major cardiovascular event (myocardial
stroke) over the following ten years, when the values of
six risk factors - gender, history of diabetes, smoking, age,
systolic blood pressure and total serum cholesterol – are known.
The risk chart:
In order to assess cardiovascular risk, glycemia and cholesterol values deriving from clinical tests are reliable only if no more than three months have passed since last measurements.
The use of risk charts to assess cardiovascular risk is highly recommended at least:
How to use the chart
Risk charts to assess the cardiovascular risk are available for: diabetic man, non diabetic man, diabetic woman, non diabetic woman. For each of these four categories the charts are further subdivided into smokers and non smokers.
Identify your age decade and your serum cholesterol and arterial pressure values.
Six cardiovascular risk categories were constructed, called MCV (from I to VI): the CVD risk category indicates how many persons out of 100 with the same characteristics will fall ill over next 10 years.
The risk categories are expressed as:
The risk factors considered are:
1. gender, expressed as two categories, men and women
2. diabetic status, expressed as two categories, diabetic and non diabetic; a person is defined diabetic if, after at least two consecutive measurements in one week, has fasting blood glucose equal to or lower than 126 mg/dl or is undergoing insuline or oral hypoglycemic agents treatement or has a family history of diabetes.
3. age, expressed in years and grouped into decades, 40-49, 50-59, 60-69
4. cigarette smoking status, expressed as two categories - smokers and non smokers. A person who smokes every day (even if only one cigarette) or has given up from less than 12 months is defined smoker. A person who has never smoked or has given up from 12 months is defined non-smoker
5. systolic arterial pressure, expressed in mmHg; it consists of the mean of two consecutive systolic blood pressure measurements performed according to the prescribed method. It is subdivided into four categories:
If a person has systolic arterial pressure higher than 200mmHg or lower than 90 mmHg the risk assessment chart cannot be used.
6. serum cholesterol, expressed in mmol/l; it is subdivided into five categories:
If a person has total serum cholesterol level greater than 320 mg/dl or lower than 130 mg/dl the risk assessment chart cannot be used.
