Objective: To study the ultrasound features of carotid atherosclerosis in patients with coronary heart disease and their correlation with disease severity. Methods: 180 patients with coronary heart disease treated in our hospital between December 2010 and December 2015 were collected as observation group and divided into single-vessel disease group (n=50), doublevessel disease group (n=72) and triple-vessel disease group (n=58) according to the degree of coronary artery stenosis; 50 healthy subjects receiving physical examination in our hospital during the same period were selected as control group. Carotid ultrasound was used to measure carotid atherosclerosis parameters, cardiac color Doppler ultrasound was used to detect cardiac function parameters, enzyme-linked immunosorbent assay (ELISA) was used to detect serum endothelial function indexes, and Pearson test was used to analyze the correlation between carotid ultrasound parameters and the cardiac function as well as endothelial function. Results: Carotid ultrasound parameters stiffness (β), elastic modulus (Ep), arterial compliance (AC) and pulse wave velocity (PWVβ) value of observation group were higher than those of control group, and with the increase of coronary artery lesion severity, the changes of β, Ep, AC and PWVβ value increased (P<0.05); cardiac function parameters left ventricular end-diastolic diameter (LVEDD) and left ventricular end-systolic diameter (LVESD) value of observation group were higher than those of control group while left ventricular ejection fraction (LVEF) value was lower than that of control group, and with the increase of coronary artery lesion severity, the changes of LVEDD, LVESD and LVEF value increased (P<0.05); endothelial function indexes endothelin-1 (ET-1) and von willebrand factor (vWF) levels of observation group were higher than those of control group while nitric oxide (NO) level was lower than that of control group, and with the increase of coronary artery lesion severity, the changes of ET-1, vWF and NO levels increased (P<0.05). Carotid ultrasound parameter β, Ep, AC and PWVβ value in patients with coronary heart disease were directly correlated with the levels of cardiac function parameters and endothelial function indexes. Conclusions: The ultrasound parameter levels of carotid atherosclerosis in patients with coronary heart disease are directly correlated with the disease severity and can be used as the noninvasive and reliable means for early judgment of the disease.
