Measurement of central augmentation index by three different methods and techniques: Agreement among Arteriograph, Complior, and Mobil‐O‐Graph devices

Wave reflection at central arteries consists of a major component of left ventricular afterload. Central augmentation index (AIx) is the most widely used surrogate of wave reflection. Recent technological developments now provide the ability to obtain, non‐invasively, aortic, or carotid pressure waves and measure AIx based on various algorithms of pulse wave analysis. The aim of this study was to compare AIx measurements performed by the...
