Assessment of central arterial pressure

Peripheral arterial pressure (taken from the radial artery of the arm) is higher than central arterial pressure (taken from the aorta). This phenomenon is known as ‘amplification’. The blood pressure values are more relevant than peripheral ones because the heart, the brain and kidneys are directly exposed to them.

The development of specific devices makes possible to approach the central pressure value non-invasively.

Central pressure correlates well with target organ damage and cardiovascular morbidity and mortality.

Estimation of central arterial pressure

What is the difference between central pressure and arm pressure?

Central blood pressure and peripheral blood pressure refer to measurements taken at different locations in the cardiovascular system and can provide different information about cardiovascular health.

What are the values obtained by estimating the central pressure?

Peripheral blood pressure (measured at the radial artery in the arm) is higher than central blood pressure (measured at the aorta) to varying degrees. This phenomenon is called ‘amplification’.

What are the advantages of central pressure analysis?

Central blood pressure has been shown to correlate more strongly than brachial pressure with damage to target organs such as the heart and large arteries.
