Abstract:
Objective To investigate the diagnostic value of echocardiography combined with three-dimensional speckle tracking imaging(3D-STI)for cardiac amyloidosis(CA)and hypertrophic cardiomyopathy(HCM).Methods Thirty-six patients with CA(CA group)and 36 patients with HCM(HCM group)who were treated at Zhengzhou Central Hospital affiliated to Zhengzhou University from September 2019 to September 2023 were selected as the research subjects.In addition,36 healthy individuals who did health check-ups at Zhengzhou Central Hospital affiliated to Zhengzhou University were selected as a control group.All patients in the three groups were tested using Doppler echocardiography to measure echocardiographic parameters[left ventricular ejection fraction(LVEF),left atrial volume index(LAVI),early diastolic mitral flow velocity/early diastolic mitral annulus velocity(E/e'),maximum left ventricular wall thickness(MLVWT),interventricular septum thickness(IVS),left ventricular end-systolic diameter(LVSED),left ventricular end-diastolic diameter(LVEDD)]and 3D-STI parameters[left ventricular three-dimensional global circumferential strain(GCS),global radial strain(GRS),global longitudinal strain(GLS),global area strain(GAS),and standard deviation of systolic peak time-GLS(Ts-SD-GLS)].The diagnostic value of each parameter for CA and HCM was analyzed using a receiver operating characteristic(ROC)curve.Results Compared with the control group,LVEF decreased,while LAVI,E/e',MLVWT,IVS,LVSED,and the proportion of patients with enlarged left atrium increased in the CA group and HCM group(P＜0.05).The proportions of patients with enlarged left atrium,enlarged atria,and pericardial effusion in the CA group were significantly higher than those in the control group,while the LVEDD was significantly lower than that in the control group(P＜0.05).LVEF,LAVI,MLVWT,IVS,LVEDD,and the proportion of patients with enlarged left atrium in the HCM group were significantly higher than those in the CA group,while E/e',LVSED,and the proportions of patients with enlarged atria and pericardial effusion were significantly lower than those in the CA group(P＜0.05).The ROC curve showed that the area under the curve(AUC)for LAVI,E/e',MLVWT,IVS,left atrial enlargement,double atrial enlargement,and pericardial effusion in diagnosing CA was 0.88,0.972,0.946,0.995,0.694,0.792,and 0.903,respectively;the AUC for LAVI,E/e',MLVWT,IVS,and LVEDD in diagnosing HCM was 0.925,0.984,0.944,0.971,and 0.553,respectively.The absolute values of GCS,GRS,GLS,and GAS in the CA group and HCM group were significantly lower than those in the control group,while the Ts-SD-GLS level was significantly higher than that in the control group(P＜0.05).The Ts-SD-GLS level in the CA group was significantly higher than that in the HCM group(P＜0.05).The ROC curve revealed that the AUC for GCS,GRS,GLS,GAS,and Ts-SD-GLS in diagnosing CA was 0.828,1.000,0.993,0.838,and 1.000,respectively;and the AUC for GCS,GRS,GLS,GAS,and Ts-SD-GLS in diagnosing HCM was 0.826,0.919,0.854,0.829,and 0.970,respectively.The AUC for combined echocardiography and 3D-STI in diagnosing HCM and CA was 0.981 and 0.996,respectively.Conclusion Echocardiography combined with 3D-STI can be used for differential diagnosis of HCM and CA,with high effectiveness.
