Correlation analysis of structural and functional changes in the carotid artery in patients with H-type hypertension using ultrasound radiofrequency.

Objectives: To perform a correlation analysis on the structural and functional changes of the carotid artery in patients with H-type hypertension.
Methods: Outpatients and inpatients with hypertension in our hospital between 2017 and 2018 were selected and divided into the H-type hypertension group (primary hypertension + plasma homocysteine ≥ 10 umol/l) ( n = 30) and the simple hypertension group (primary hypertension + plasma Hcy < 10 umol/l) ( n = 30) based on the plasma homocysteine (Hcy), and 30 healthy people were included in the control group. Thickness and stiffness parameters of the intima of the carotid artery (compliance coefficient [CC], stiffness index [β], and pulse wave velocity [PWV]) were measured for all study participants using ultrasound radiofrequency signal-based quality intima-media thickness (QIMT) and quantitative arterial stiffness (QAS) for contrast analysis.
Results: Indexes such as QIMT, β, and PWV of the carotid artery were significantly higher, and the CC was significantly lower in the H-type hypertension group and simple hypertension group than the control group ( p < .05), and the difference was statistically significant; these indexes were significantly higher in the H-type hypertension group than in the simple hypertension group, and the CC was significantly lower than in the control group ( p < .05), and the difference was statistically significant.
Conclusions: Hypertension can accelerate structural and functional changes of the carotid artery intima, with these changes being more significant in H-type hypertension. The ultrasound radiofrequency technique can be used to quantitatively evaluate the structure and function of the carotid artery in patients with H-type hypertension.
