PP is the difference between the systolic (max) and diastolic (min) pressure and is often used to measure arterial stiffness, as it reflects the pulsatile component of blood pressure, the difference between the extremes is called the
Pulse Pressure (PP) Normal PP in the brachial artery is approximate 40 mm Hg (e.g. 120 SBP/80 DBP.).
Increased PP may be due to several reasons, e.g. exercise (temporary increase),
anaemia, Hyperthyroidism, arterial stiffening (usually about 50-60 years). Studies have also shown that PP is a strong and independent predictor of CV events.
