Abstract:
Objective To evaluate the vascular remodeling features in the elderly hypertensives through detecting the changes of large arterial structure and function by ultrasonography. Methods High resolution ultrasound was applied to examine 52 lightly or moderate elderly hypertensives(LMEH), 52 elderly normal subjects(EN) and 25 adult normal subjects(AN). Carotid and humeral arterial intimal-medial thickness (IMT), lumen diameter(r) and IMT/r were determined as the index for the changes of arterial structure, and the humeral arterial endothelium-dependent vasodilation and cross-sectional compliance were used to reflect the changes of arterial functions. Results Carotid IMT and lumen diameter were larger in LMEH group than those in EN group(0.97?0.21)% vs. (0.82?0.12)%, (7.41?2.13)% vs. (6.38?0.45)%, all P
