Evaluation of ultrasonography on carotid arteries and left ventricular function in patients with subclinical atherosclerosis

Ultrasonography in the evaluation and diagnosis of carotid arteries and left ventricular function in patients with subclinical atherosclerosis (SA) was explored. In total, 152 patients with no obvious clinical symptoms of atherosclerosis confirmed by carotid ultrasonography in Tengzhou Central People's Hospital from September 2015 to March 2016 were enrolled as the experimental group, and further 45 patients with normal physical examination at the same time were collected as the control group. Patients in the experimental group were divided into three groups according to Framingham risk assessment: low, middle and high risk. The carotid arteries and left ventricular function of all patients were detected by Doppler ultrasound. There were differences in the systolic pressure, TG and TC between the control group and the experimental group (P<0.05). The expression levels of β, cIMT, Ep and PWVβ increased with the risk degree in the low, middle and high risk groups (P<0.05). The expression levels of LVEDV, LVESV, and LVEF in the experimental group were significantly decreased compared with those in the control group (P<0.05), while the expression levels of LAV, E/e, GLS and GCS were significantly increased compared with those in the control group (P<0.05). There was a difference of left ventricular function parameters in the low, medium and high risk groups (P<0.05). The expression levels of LVEDV, LVESV, LAV and E/e increased with the risk degree in the low, middle and high risk groups (P<0.05). The detection rate of plaque was lower in the low risk group than those in the middle and high risk group (P<0.05). By observing the parameters of carotid arteries and left ventricular function, it was found that ultrasonography has important clinical value in the early diagnosis of SA, and can be promoted in clinic.
