Relationship between structural changes of intima-media and distensibility of the carotid in primary hypertension / 中华超声影像学杂志

ABSTRACT

ObjectiveTo explore the wall structural ch anges of the carotid with integrated backscatter and their effects on wall distensibility in patients with primary hypertension. MethodsForty-three patients with primary hypertension and 25 normal subjects were enrolled in the study. The corrected integrated backscatter (CIBS) and its cyclic variability (CVIB), the thickness of intima-media (IMT) and the carotid distensibility (CD) were compared between hypertensive group and normal control group. ResultsCIBS and IMT were increased while CD was decreased more significantly in hypertensive patients than in normal subjects. Demonstrated a negative correlation with CD but a positire correlation with IMT in hypertensive patients. ConclusionsThe wall structural changes of the carotid are closely correlated with the functional disorder in patients with primary hypertension.
