Citation: Gbaoui L, Hoeschen C, Kaniusas E, Khatib S, Gretschel S and Wellnhofer .Central (aortic) blood pressures differ from brachial pressures and may be more relevant to the study of cognitive function, given that blood is delivered to the brain through the central large arteries.Systolic blood pressure (SBP) is amplified along conduit arteries such that peripheral SBP (pSBP) measured at the brachial or radial artery usually exceeds central aortic systolic pressure (cSBP) at the aortic root.
