RESUMEN
Objective At present, there are few reports on the stability of carotid plaque and left ventricular function at home and abroad. The article investigated the factors influencing the stability of left ventricular function on carotid atherosclerotic plaque. Methods 90 patients with carotid atherosclerosis (carotid intima-media thickness >0.2 cm) admitted in the Department of Neurology, Jiangsu Provincial Hospital of Traditional Chinese Medicine from June 10, 2017 to January 8, 2019 were selected and their stability of plaques was graded by contrast-enhanced ultrasound (CEUS). The patients were divided into two groups according to the stability of plaque. The differences of general clinical data, related biochemical indexes and left ventricular function indexes between the two groups were compared. The effects of left ventricular structural function on plaque stability were examined by logistic multivariate regression analysis. Results Univariate analysis showed that E peak (χ2=2.170, P=0.034), ventricular septal thickness (χ2=-1.972, P=0.049), diabetes history (χ2=10.102, P=0.001) were the risk factors of plaque stability and the differences were statistically significant (P < 0.05). Multivariate analysis showed that E peak (OR=0.022, P=0.014) and diabetes history (OR=0.185, P=0.002) were independent influencing factors of plaque stability. Conclusion There is an independent correlation between left ventricular function and plaque stability, and plaque stability can predict changes in ventricular structural function.
RESUMEN
Objective@#To analyze the clinical significance of contrast-enhanced ultrasound in the treatment of patients with carotid stenosis.@*Methods@#The clinical data of 89 patients with carotid stenosis was retrospectively analyzed.The morphology and stenosis of carotid plaques were observed by contrast-enhanced ultrasound, and analyzing the relationship between the patient′s clinical symptoms and treatment options.@*Results@#There were 66 males, 23 females, age ranging from 41 to 88 years.There were 147 plaques in 89 patients and 58 patients with bilateral lesions. The intensity of plaque ultrasound contrast was grade Ⅰ in 40 cases(27%), grade Ⅱ in 30(20%), grade Ⅲ in 31(21%), andgrade Ⅳ in 46(31%). The symptomatic group had higher CEUS strengths in grade Ⅲ(21.4%) and grade Ⅳ(37.9%). The difference was statistically significant between the two groups (P<0.05). Symptomatic group with high proportion of severe stenosis (44.7%) and occlusion (9.7%). It is narrower than that of asymptomatic group.The difference of stenosis was statistically significant between the two groups (P<0.05).@*Conclusion@#Contrast-enhanced ultrasound can dynamically and visually assess the distribution and density of carotid plaque morphology. It is useful for evaluating the treatment of patients with carotid stenosis.
