Pulse Pressure And Mean Arterial Pressure

Systolic (sbp) and diastolic (dbp) blood pressures, pulse pressure and mean arterial pressure singly predicted cvd mortality. Pulse pressure (pp), defined as the difference between systolic blood pressure (sbp) and diastolic blood pressure (dbp), is a pulsatile component of the blood pressure (bp) curve as opposed to mean arterial pressure (map), which is a steady component. For example, if systolic pressure is 120 mmhg and diastolic pressure is 80 mmhg (as shown in the figure), then the mean arterial pressure is approximately 93 mmhg using this calculation.

The mean arterial pressure (map) usually serves as an expression of blood pressure in patients on chronic haemodialysis (pchd), instead of using solely systolic or diastolic pressure. You then follow this equation: Abstract —we compared systolic blood pressure (sbp), diastolic blood pressure (dbp), pulse pressure (pp), and mean arterial pressure (map) in predicting the risk of cardiovascular disease (cvd), stratifying results at age 60 years, when dbp decreases while sbp continues to increase.

It is generally a sign of arterial stiffness and may increase your risk for heart disease and other conditions [ 6 ]. Your pulse pressure can also sometimes that you’re at risk for certain diseases or conditions. For a person with a blood pressure of 120/80, for example, the mean arterial pressure would be approximately 80 + 1/3 (40) = 93 mmhg. The bottom number is the amount of pressure in the arteries between beats (diastolic pressure).
