ABSTRACT
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.
