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

AI Article Synopsis

  • The study looked at how high blood pressure, especially H-type hypertension, affects the carotid artery's structure and function.
  • Researchers compared two groups of people with hypertension and one healthy group to see differences in their carotid arteries.
  • Results showed that people with H-type hypertension had more significant changes in their carotid arteries compared to those with simple hypertension and healthy individuals.

Article Abstract

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) ( = 30) and the simple hypertension group (primary hypertension + plasma Hcy < 10 umol/l) ( = 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 ( < .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 ( < .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.
