Hypertension puts continuous strain on arteries, resulting in arterial wall alterations such as vessel wall thickening and vessel wall stiffening... Due to the availability of suitable acoustic windows, vessel wall thickness (VWT) is studied traditionally by ultrasound from intima-media thickness in the carotid arteries... Arterial vessel wall stiffness can be expressed by Pulse Wave Velocity (PWV), the propagation speed of the systolic wave front through the aorta... At the same day, aortic and carotid vessel wall imaging was performed on 3T MRI-scanner (Philips Medical Systems, Best, the Netherlands) using three-dimensional (for aorta) and multi-two-dimensional (for carotid artery) dual-inversion black-blood gradient-echo sequences with 0.5×0.5mm in-plane resolution, spectral-selective fat suppression and navigator respiratory-compensation (for aorta)... Mean VWT was computed and indexed for Body Surface Area (BSA): ∑ [(area vessel wall × slice thickness) / total number of slices]/BSA... Hypertensive patients presented with higher PWV and aortic and carotid VWT than healthy volunteers (Table 1)... Associations between PWV, aortic and carotid VWT and with age are presented in Figure 1... PWV and aortic and carotid VWT were all significantly associated with age, and all associations were not different between patients and volunteers... Association between aortic PWV and aortic VWT was stronger than for aortic PWV and carotid VWT... Finally, aortic VWT correlated with carotid VWT... MRI presents associations between aortic and carotid VWT and aortic PWV, and all parameters are increased in patients with hypertension versus age- and gender-matched healthy volunteers.

Figure 1: Associations between aortic PWV and aortic and carotid VWT indexed for BSA, and with age.

Mentions: Hypertensive patients presented with higher PWV and aortic and carotid VWT than healthy volunteers (Table 1). Associations between PWV, aortic and carotid VWT and with age are presented in Figure 1. PWV and aortic and carotid VWT were all significantly associated with age, and all associations were not different between patients and volunteers. Association between aortic PWV and aortic VWT was stronger than for aortic PWV and carotid VWT. Finally, aortic VWT correlated with carotid VWT.
