Abstract:
Objective:To investigate the value of cardiac color ultrasound combined with cardiac ankle vascular index(CAVI)and ankle brachial index(ABI)in the early diagnosis of coronary heart disease.Methods:A total of 146 patients with coronary heart disease admitted to Leshan People's Hospital from December 2019 to December 2022 were included in the observation group,and 70 healthy persons who underwent physical examination in the hospital during the same period were included in the healthy control group.Both groups underwent cardiac color ultrasound and the examinations of CAVI and ABI.Myocardial performance index(Tei index),ratio of diastolic peak E velocity(E)to late diastolic peak A velocity(A)(E/A),left atrial diameter(LAD),left ventricular ejection fraction(LVEF),CAVI and ABI levels were compared between the two groups.Receiver operating characteristic(ROC)curve was plotted to analyze the values of Tei index,E/A,LAD,LVEF,CAVI and ABI in the alone diagnosis of coronary heart disease.The result of coronary angiography was used as the gold standard,and the consistency was used to analyze the efficacy of the combined diagnosis of Tei index,E/A,LAD,LVEF,CAVI and ABI coronary heart disease.Results:The Tei index,LVEF and CAVI levels in the observation group were significantly higher than those in the healthy control group(t=19.357,25.728,21.766,P<0.05),and the E/A,LAD and ABI levels in the observation group were significantly lower than those in the healthy control group(t=7.721,2.769,10.610,P<0.05),respectively.The ROC analysis proved that Tei index,E/A,LAD,LVEF,CAVI and ABI could be used to diagnose coronary heart disease.The areas under curve(AUC)values of them were 0.914,0.796,0.553,0.950,0.930 and 0.834,respectively.The result of consistency analysis indicated that the sensitivity,specificity,accuracy and Kappa value of the combined diagnosis of Tei index,E/A,LAD,LVEF,CAVI and ABI were respectively 0.986,0.929,0.968 and[0.925(P<0.05)]in diagnosing coronary heart disease.Conclusion:Tei index,E/A,LAD,LVEF,CAVI and ABI can be used to diagnose coronary heart disease,and the combined diagnosis of them has higher efficiency.
