Diagnostic Value of Cardiac Magnetic Resonance Imaging Combined with Echocardiographyin Patients With Hypertrophic Cardiomyopathy
Objective To explore the diagnostic value of cardiac magnetic resonance(CMR)combined with echocardiography(UCG)in hypertrophic cardiomyopathy(HCM).Methods A total of 80 HCM patients admitted to Handan Central Hospital from January 2020 to February 2023 were selected as the study group,and 80 healthy people who underwent physical examination during the same period were randomly selected as the control group.All subjects underwent CMR and UCG tests to compare the differences in CMR and UCG quantitative parameters between the two groups.Multivariate Logistic regression analysis was performed to plot receiver operating characteristic curve(ROC)and calculate area under the curve(AUC)to evaluate the efficacy of CMR and UCG quantitative parameters in the diagnosis of HCM alone and in combination.Results In the study group,CMR parameters[left ventricular ejection fraction(EF),end-diastolic left ventricular mass(LVEDM),left ventricular wall thickness at the thickest point(MWT),gadolinium-delayed reinforcement(LGE)positive ratio)],UCG parameters[end-diastolic posterior left ventricular wall thickness(LVPWD),end-diastolic septal thickness(IVSD),MWT,mitral valve oral relaxation The ratio of blood flow velocity to the mean value of interventricular septum and lateral wall(E/e')and EF]in early Zhang period were significantly higher than those in control group(P＜0.05).The CMR parameters[left ventricular end-diastolic volume(EDV),left ventricular end-systolic volume(ESV)],UCG parameters[left ventricular end-diastolic transverse diameter(LVEDD),ratio of early diastolic blood flow velocity to late diastolic blood flow velocity(E/A),EDV,ESV]were significantly lower than those of control group(P＜0.05).Multivariate Logistic regression analysis and ROC curve showed that compared with single parameter diagnosis,CMR combined with UCG quantitative parameters had the highest AUC,Yoden index,sensitivity and specificity for HCM diagnosis(P＜0.05).Conclusion CMR combined with UCG has higher diagnostic value for HCM,and has certain imaging reference for the selection of clinical diagnosis and treatment.
