Abstract

Objective: To assess the agreement and reproducibility of the non-invasive measurement of the central systolic blood pressure (cSBP), second systolic shoulder (SYS2), and augmentation index (AIx) with the OMRON HEM-9000AI.Design and method: This cross-sectional study was conducted in 36 healthy Mexican individuals. The cSBP, SYS2, and AIx were measured. All values are expressed as mean ± SD; the correlation was analyzed using Pearson's correlation coefficient and the Bland Altman method for agreement. All p-values were two-tailed, and p<0.05 was accepted as statistically significant. Results: The mean age of participants was 20.6 ± 1.6 years, mean BMI was 23.5 ± 3.5 and mean waist circumference was 82.5 ± 9.3 cm. Good correlation between the first and second measurements was exhibited by cSBP (r2 Pearson = 0.680), SYS2 (r2 Pearson = 0.680), and AIx (r2 Pearson = 0.675) (p < 0.001 for all). The Bland–Altman plots of the first and second SYS2 and AIx measurements also demonstrated good agreement (respective mean differences: 2.4 ± 6.07 mmHg and 0.029 ± 8.39%). Figure 1. Conclusions: The results obtained demonstrate that there are strong and significant correlations between the first and second measurements of cSBP, SYS2, and AIx, respectively.
