CMR-assessed aortic arch stiffness is associated with brain tissue integrity assessed by diffusion tensor imaging in patients with hypertension

Table 1 Association between CMR-assessed aortic arch PWV and brain volume, white matter lesion volume, and DTI measures of brain microstructure.

Brain volume (cm²)	β	P-value
White matter	-0.22	0.094
Grey matter	-0.18	0.061
Ln white matter lesion volume (mL)	0.05	0.713
FA
White matter	-0.30	0.011*
Grey matter	0.01	0.938
MD
White matter	0.31	0.005*
Grey matter	0.28	0.006*
AxD

P-values are from linear regression analysis, adjusting for age, gender, body mass index, smoking, mean arterial blood pressure, duration of hypertension and cerebrovascular disease. FA: fractional anisotropy; MD: mean diffusivity; AxD: axial diffusivity; RD: and radial diffusivity. * P-value < 0.05.
