Risk classification - General Information
In 1999 the World Health Organization (WHO) issued guidelines for the classification of the risk of a cardiovascular event (1999 World Health Organization - International Society of Hypertension Guidelines for the Management of Hypertension; Journal of Hypertension 1999, 17:151-183).
According to these guidelines, patients with high blood pressure are classified into four different risk classes. Along with blood pressure, the following risk factors are analyzed:
- Smoking Status
- Family history of premature cardiovascular disease
A Microlife blood pressure monitor with risk classification enables these factors to be easily entered using the «Risk Factor Input» button. Together with the blood pressure measurement, the number of risk factors is evaluated to determine a risk categorisation. This is performed automatically and displayed after the measurement is taken.
NOR (Normal) is displayed when the systolic measurements are below 140 and diastolic measurements are below 90 mmHg.
