Beat-to-beat blood pressure indices were significantly correlated with two-dimensional common carotid artery wall displacement indices (r = 0.787, p < 0.05), with the displacement/pressure curve slope progressively reducing with age and essential hypertension.

Does the physiological relationship between 2D carotid artery wall displacement and beat-to-beat blood pressure correlate with arterial stiffness, age, and essential hypertension?
Effect estimate: r = 0.787
p-value: p=<0.05
The physiological relationship between local arterial displacement and blood pressure (BP) plays an integral role in assess- ment of the mechanical properties of arteries. In this study, we used more advanced methods to obtain reliable continuous BP and the displacement of the common carotid artery (CCA) simultaneously. We propose a novel evaluation method for arterial stiffness that relies on determining the physiological relationship between the axial and radial displacements of the CCA wall and beat-to-beat BP. Patients (total of 138) were divided into groups according to the following three criteria: essential hyper- tension (EH) and normotension, male and female, elderly and younger. The Pearson correlation test and canonical correlation analysis showed that the CCA indices were significantly correlated with BP indices (r = 0:787; p 60:0.783). Our method provides an explicit reference value and relationship for the manner in which the CCA wall responds to changes in BP. Short-term and continuous BP were significantly correlated with CCA displacement and exhibited a close inverse relationship with each subject's BP and EH, age, and systolic blood pressure.
Xu et al. (Mon,) conducted a cross-sectional in Essential hypertension (n=138). Simultaneous measurement of beat-to-beat blood pressure and 2-D carotid artery wall displacement vs. Normotension, younger age, or female sex was evaluated on Canonical correlation between common carotid artery (CCA) indices and blood pressure (BP) indices (r = 0.787, p=<0.05). Beat-to-beat blood pressure indices were significantly correlated with two-dimensional common carotid artery wall displacement indices (r = 0.787, p < 0.05), with the displacement/pressure curve slope progressively reducing with age and essential hypertension.
