This study sought to compare the estimation of central systolic blood pressure (cSBP) obtained by two different noninvasive devices, in addition to its comparisons with measured peripheral systolic blood pressure (pSBP), in a biracial (Black/White) community-based cohort. Estimations of cSBP by applanation tonometry were obtained in 586 participants of the Bogalusa Heart Study (mean age: 43.5 years; 69% White, 54% women) using two different commonly used instruments: Omron HEM-9000AI and SphygmoCor CPV. pSBP was measured using a standard auscultatory technique. The estimation of cSBP by the Omron device was higher than that of the SphygmoCor device (124.2±17.1 vs. 111.4±15.2 mmHg, P<0.001). Moreover, cSBP by Omron was significantly higher than peripheral blood pressure (124.2±17.1 vs. 119.4±15.6 mmHg, P<0.001), whereas cSBP by SphygmoCor was significantly lower than pSBP (111.4±15.2 vs. 119.4±15.6 mmHg, P<0.001). Similar results were observed in race-specific and sex-specific analyses. These findings support the hypothesis that notable differences exist in the estimation of cSBP provided by the instruments utilized in this study. Further standardization studies are required to establish the most appropriate noninvasive estimation of cSBP before this parameter may be considered in the assessment, prediction, and prevention of cardio-metabolic risk and overt cardiovascular disease in clinical practice.
