Abstract:Objective: To explore the diagnostic value of cervical cerebral integrated ultrasound combined with red blood cell distribution width in coronary heart disease.Methods: 80 patients with coronary artery stenosis diagnosed by coronary angiography (CAG) in the Department of Cardiology of our hospital from January 2019 to December 2020 were selected as the observation group, and 80 patients without coronary artery stenosis diagnosed by coronary angiography were selected as the control group. The levels of transcranial Doppler ultrasound (TCD) detection parameters (mean flow velocity VM), transcranial vascular ultrasound detection parameters (IMT) and red blood cell distribution width (RDW) in each group were compared. Results: The mean flow velocity (VM), common carotid artery intima-media thickness (IMT) and RDW levels of MCA, ACA and PCA in the observation group were significantly higher than those in the control group (P<0.05). The area under the ROC curve of VM, IMT, RDW and combined detection for diagnosing coronary heart disease were 0.83, 0.81, 0.77 and 0.91, respectively. There were statistically significant differences in the area under the ROC curve of each diagnosis of coronary heart disease(P<0.05). When VM ≥ 2.03m/s, IMT ≥ 1.05mm and RDW ≥ 14.65% were present at the same time, the diagnostic sensitivity and specificity were 91.25% and 98.75%, respectively. The sensitivity and specificity of parallel combined detection were significantly better than that of general single test (P<0.05). Conclusion: The level of detection parameters determined by cervical cerebral integrated ultrasound combined with red blood cell distribution width is closely related to the occurrence of coronary heart disease. It has great diagnostic value for the diagnosis of coronary heart disease, and has great economic and social value.
