Abstract:
Objective:To observe the value of two-dimensional echocardiography(2DE)combined with color Doppler flow imaging(CDFI)in the diagnosis for hypertrophic cardiomyopathy(HCM).Methods:A total of 480 HCM patients who admitted to Northwest Women's and Children's Hospital from January 2019 to January 2021 were selected as case group,and 200 healthy individuals who underwent health physical examination were included into health control group.All receivers underwent 2DE and CDFI examinations,and the 2DE and CDFI detection indicators of two groups were calculated by statistical method and were compared.The diagnostic efficacies of single 2DE,single CDFI and the combination of them were analyzed.Results:The thickness of left ventricular posterior wall(LVPW),interventricular septum thickness(IVST)and left atrial diameter(LAD)of the case group were significantly higher than those of the control group,and the differences were statistically significant(t=5.896,14.861,8.974,P<0.05),respectively.The E peak/A peak(E/A)of anterior flow of mitral valve and early diastolic velocity of mitral valve(Em)of the case group were respectively lower than those of the health control group,while the early diastolic blood flow velocity of mitral valve opening(E)/Em(E/Em)of the case group was higher than that of the health control group,with statistically significant differences(t=6.782,5.189,10.738,P<0.05).The optimal critical points(detection sensitivity)of the receiver operating characteristic(ROC)curves of single 2DE,single CDFI and combination of them in diagnosing HCM were respectively 67.83%,65.38%and 82.38%.The detection specificities of them were respectively 65.48%,64.58%and 80.66%.The area under curve(AUC)values of ROC curves of them were respectively 0.6835,0.6949 and 0.8136,and the accuracies of them were respectively 68.35%,69.49%and 81.36%,and the 95%confidence intervals of them were respectively 0.608-0.803,0.606-0.823 and 0.835-0.943.The sensitivity,specificity and accuracy of the combination of 2DE and CDFI were respectively higher than those of single 2DE and CDFI.Conclusion:Both 2DE and CDFI have a certain value in diagnosing HCM,but their combination can further improve the diagnostic efficacy for HCM.
