Abstract
The development of non-invasive technology to perform pulse wave analysis and accurately determine central blood pressure has facilitated the study of central blood pressure as a physiologic and biomarker parameter. Central systolic blood pressure (cSBP) has been shown to be significantly associated with adverse outcome such as mortality and associated with adverse outcome. One of the most commonly evaluated features of the arterial pressure waveforms is augmentation index (AIx). Nowadays, there are multiple devices that have been developed for calculate AIx at peripheral arteries. The aim of our study was to assess the repeatability measurements of second systolic shoulder of the radial waveform (pSBP2) and peripheral augmentation index (pAIx) using the OMRON HEM-9000AI. 36 young subjects were studied. The paired t student test showed no significant difference. The mean difference between the two consecutive measures of pSBP2 was 0.3 ± 4; P = 0.58, pAIx (0.3 ± 7; P = 0.80) and pAIx75 (0.5 ± 6.6; P = 0.62). This study demonstrates good repeatability and reliability of this method in our study population, compared to other populations the variability between measurements.
