Abstract
Objective To explore the diagnostic value of color Doppler echocardiography combined with carotid artery ultrasound on coronary heart disease(CHD).Methods A total of 90 cases suspected with CHD were included,and all underwent color Doppler echocardiography and carotid artery ultrasound examinations.Taking coronary angiography results as the gold standard,we compared the ultrasound parameters of patients between the CHD group(with positive angiography results)and the non-CHD group(with negative angiography results).We also analyzed the changes of each ultrasound parameter in CHD patients with different numbers of diseased coronary arteries.The diagnostic value of myocardial work index(Tei index),plaque score,intima-media thickness(IMT),and the combination of the above three indexes for CHD were all assessed.Results In the CHD group,the values of Tei index,plaque score,and IMT were all significantly higher than those in the non-CHD group(all P<0.01).Among the 52 patients with CHD,there were 30 cases with single-vessel disease,14 cases with double-vessel disease,and 8 cases with multi-vessel disease.There were statistically significant differences in Tei index,plaque score,and IMT among CHD patients of subgroups with different numbers of diseased coronary arteries(all P<0.01);and the values of the above indexes in the multi-vessel lesion subgroup were all significantly higher than those in the double-or single-vessel lesion subgroups(all P<0.05).ROC curve analysis showed that the AUC,Youden index,sensitivity,and specificity of IMT in the diagnosis of CHD was the highest among the above three ultrasound indicators;the values of AUC and sensitivity of the combination of the above three indexes were both significantly higher than those of any single index for the diagnosis of CHD.Conclusion The combination of color Doppler echocardiography and carotid artery ultrasound examinations help to determine the degree of coronary artery disease,and improve the diagnostic efficiency of CHD.It has relatively high value of popularization and application.关键词
