[Ultrasonographic study on effects of Wendan Xiezhuo method in improving vascular endothelial diastolic function and atherosclerosis in hypertension patients with turbid-phlegm syndrome].

Abstract

OBJECTIVE:

To observe the effect of Wendan Xiezhuo method (WXM) on carotid arteriosclerosis and vascular endothelial diastolic function in essential hypertension (EH) patients with turbid-phlegm syndrome (TPS).

METHODS:

Forty-three EH patients of medium and low risk with TPS were randomly assigned to two groups, the Wendan Tablet (WT) group (23 cases) and the placebo group (20 cases), they were treated with WT and placebo respectively on the base of amlodipine treatment to control the blood pressure. Carotid intimamedia thickness (IMT), atherosclerotic plaque score of carotid artery, endothelium-dependent dilation (EDD) and flow-mediated vasodilation (FMD) of brachial artery after taking nitroglycerin were detected with ultrasonography before and after 6 months of treatment.

RESULTS:

As compared with those in the placebo group, in the WT group after treatment, scores of TPS and carotid plaque were better, area of carotid plaque was lesser and IMT was lower significantly (P<0.05 or P<0.01). There was a negative correlation between brachial artery EDD and carotid IMT in EH patients with TPS (r = - 0.596, P < 0.05). After treatment EDD was improved more significantly in the WT group than that in the placebo group, however, no significant difference was found in non-endothelium-dependent dilation between the two groups.

CONCLUSION:

A negative correlation exists between brachial artery EDD and carotid IMT, and the latter could be aggravated by TPS in EH patients. WXM shows favorable effects in improving carotid plaque and EDD.
