Abstract：Objective: To study the relationship between the vulnerable plaque of carotid artery and the coronary SYNTAX score, and to explore the predictive effect of carotid atherosclerosis index on SYNTAX score and prognosis in patients with coronary heart disease. Methods: 315 cases underwent coronary angiography in Chengde central hospital from March 2016 to May 2017 were enrolled in the study. And the SYNTAX score was calculated according to coronary angiography, and divided into four groups: mild group (1 ≤points <21) in 124 cases, moderate group (21≤ points <31) in 63 cases, severe group (more than or equal to 31 points) in 45 cases, the control group of 83 cases (0); At the same time, the situation of carotid artery atherosclerosis was detected by ultrasound, and the number and texture of vulnerable plaques were measured and recorded, and the corresponding evaluation was made. Results: The detection rate of vulnerable plaque of carotid artery was compared between the four groups. Compared with the mild group, the control group had a significant difference compared with the severe group (P<0.05). The proportion of vulnerable plaque in carotid artery was compared between the four groups. There was a significant difference between the groups (P<0.05). As SYNTAX score increased, mixed plaques hypoechoic accounted ladder in each group except the severe group increased; the other three groups, high echo mixed echo plaque in each group in proportion gradually increased; plaque heterogeneity was not statistically significant (P>0.05). There was no significant difference between the follow-up patients after 1 months of follow-up after discharge (P>0.05). Conclusion: Carotid vulnerable plaques, especially low echo mixed echo plaques are significantly correlated with coronary artery lesions. Ultrasound detection of vulnerable carotid plaques has great clinical value for early diagnosis and prevention of coronary heart disease, and it is worthy of further excavation.
