Abstract: This study investigated the value of intracranial and extracranial integrated cervical cerebral ultrasound features combined with homocysteine (Hcy) and high-sensitivity C-reactive protein (hs-CRP) in evaluating the degree of coronary atherosclerosis. 120 patients with suspected coronary heart disease were selected, and 82 patients were diagnosed with coronary heart disease by coronary angiography (CAG), including 45 patients with mild coronary artery stenosis and 37 patients with moderate to severe coronary artery stenosis. All patients underwent transcranial Doppler ultrasound and carotid artery ultrasound examination, compared the differences in clinical data and ultrasound parameters between patients with coronary heart disease and without coronary heart disease, patients with different degrees of coronary artery disease, and analyzed the influencing factors of moderate to severe coronary artery stenosis. The results showed that the levels of Hcy and hs-CRP in CHD patients were higher than those in non-CHD patients (P<0.05). The age, total cholesterol (TC), triglyceride (TG), Hcy, hs-CRP, carotid Crouse plaque score and intima-media thickness (IMT) of patients with moderate to severe stenosis were higher than those of patients with mild stenosis (P<0.05), while the mean intracranial artery velocity, end-systolic velocity (PSV) and end-diastolic velocity (EDV) were lower than those of patients with mild stenosis (P<0.05). Carotid crouse plaque score, carotid IMT, Hcy and hs-CRP were positively correlated with Gensini score (P<0.05). The Logistic regression equation showed that Hcy, hs-CRP, carotid Crouse plaque score and carotid IMT were the influencing factors of moderate to severe coronary artery stenosis in patients with coronary heart disease (P<0.05). The area under the ROC curve of Logistic regression equation for predicting moderate to severe stenosis was 0.962 (P<0.05). The intracranial and extracranial integrated cervical cerebral ultrasound features combined with Hcy and hs-CRP have a good effect on evaluating and predicting the degree of coronary atherosclerosis.
