Abstract
Objective To investigate the diagnostic value of echocardiography combined with myocardial marker detection for dilated cardiomyopathy(DCM).Methods A total of 120 patients with suspected DCM were selected,and divided into an observation group(DCM patients,n=75)and a control group(non-DCM patients,n=45)using cardiac magnetic resonance(CMR)as the gold standard.The detection rate of DCM by echocardiography was analyzed;echocardiographic parameters were compared between the two groups;myocardial marker levels were also compared;the diagnostic efficacy of echocardiography combined with myocardial markers for DCM was evaluated using ROC curve analysis.Results The detection rate of DCM by echocardiography was 82.67%.Left ventricular end-diastolic diameter(LVEDD)and left ventricular end-systolic diameter(LVESD)in the observation group were both significantly higher than those in the control group,while left ventricular ejection fraction(LVEF)was significantly lower(all P<0.05).The levels of N-terminal pro-B-type natriuretic peptide(NT-proBNP)and cardiac troponin I(cTnI)in the observation group were both significantly higher than those in the control group(both P<0.05).The area under the curve(AUC)for the combined detection of echocardiography and myocardial markers was 0.954,with a sensitivity of 94.67%and a specificity of 93.33%,which was significantly higher than that of either single detection method(P<0.05).Conclusion Echocardiography combined with myocardial marker detection has high diagnostic value for DCM.关键词
