Carotid arterial hemodynamics in patients with essential hypertension of different dialectical types of traditional Chinese medicine

Abstract

To probe into the relationship between traditional Chinese medicine (TCM) different dialectical types of essential hypertension and carotid artery hemodynamics. According to TCM, different dialectical types, 189 patients suffering from essential hypertension were divided into five type groups by two deputy chief physicians of TCM, according to TCM diagnosis and treatment guide for hypertension prepared by the Chinese society of TCM in 2011. A total of 189 patients were examined by transcranial color doppler (TCD) and compared with 47 normal subjects. The measuring target included middle cerebral artery (MCA) and anterior cerebral artery (ACA), recording the average blood flow velocity (Vm) and vascular pulse index (PI). In MCAVm and ACAVm, hyperpyrexia of liver syndrome showed unique advantages and positive correlation. In MCAPI and ACAPI, internal block because of phlegm dampness, stasis syndrome, deficiency of qi and blood syndrome, and internal block because of blood stasis syndrome had advantages and positive correlation, and the above three groups were not statistically significant. Our study determined different dialectical types and objective material foundations of TCM in hypertension, correlating with carotid artery hemodynamics. Also, dialectical treatment would reduce the cerebrovascular accident.
