These guidelines acknowledged that central (aortic) blood pressure (BP), which is the pressure exerted on the heart and brain, may be different from the pressure that is measured at the arm. They also recognized that central pressure may be predictive of outcome in specific populations2 and differently affected by antihypertensive drugs. However, although these guidelines accepted that central augmentation index and pulse wave velocity may be important as measures of subclinical organ damage, they also stressed the need for prospective trials to establish their predictive values given that such studies were lacking at that time (2003).
After publication of these guidelines, additional data have strengthened the pathophysiological importance of central BP. Clinical studies have indicated that central BP may have predictive value independent of the corresponding peripheral (brachial) BP. More importantly, recent large-scale trials have shown that central hemodynamics may provide a worthwhile treatment target. In addition, central hemodynamics can now be reliably assessed noninvasively with a number of devices. Accordingly, because arterial stiffening and central hemodynamics are markers and manifestations of organ damage, the pertinent key question is whether the balance of evidence on their importance and issues related to clinical practice allows for implementation in patient management.
