Cardiovascular disease

Blood pressure is measured as two numbers, written one over the other and recorded in
millimetres of mercury – for example, 120/78 mm Hg. The top (higher) number is the systolic
pressure – the pressure in the arteries as the heart is contracting – and the bottom (lower)
number is the diastolic pressure – the pressure in the arteries when the heart is relaxed between
beats. High blood pressure is defined as a repeatedly elevated systolic pressure of 140 or higher
OR a diastolic pressure of 90 or higher
