Blood Pressure consists of Systolic and Diastolic readings and is usually written as two numbers Systolic / Diastolic e.g. 140/90 mmHg
- Systolic blood pressure (the first number) – indicates how much pressure your blood is exerting against your artery walls when the heart beats.
- Diastolic blood pressure (the second number) – indicates how much pressure your blood is exerting against your artery walls while the heart is resting between beats.
- Typically, more attention is given to systolic blood pressure as a major risk factor for CVD for people over 50.
- Either an elevated systolic or an elevated diastolic blood pressure reading may be used to make a diagnosis of high blood pressure.
- The risk of death from ischemic heart disease and stroke doubles with every 20 mm Hg systolic or 10 mm Hg diastolic increase among people from age 40 to 89.
These categories are based on the American Heart Foundation's classification.
