Diagnostic Value of Multi-parameter Echocardiography in Asymptomatic Myo-cardial Ischemia During Geriatric Outpatient Health Examinations
摘要
Abstract
Objective:To evaluate the diagnostic value of multi-parameter echocardiography[including left ventricular ejection fraction(LVEF),global longitudinal-strain(GLS),early systolic lengthening time,left ventricular myocardial performance index(Tei index)]in asymptomatic myocardial ischemia during geriatric outpatient health examinations.Methods:95 patients with asymptomatic myocardial ischemia undergoing geriatric outpatient health examinations at the First Affiliated Hospital of Air Force Medical University from January 2022 to February 2024 were retrospectively selected as the study group.Another 95 healthy elderly individuals undergoing health examinations during the same period were selected as the control group.All subjects underwent Philips CX50 echocardiography.General information and echocardiographic parameters were collected.Logistic regression analysis was used to assess the relationship between echocardiographic parameters and asymptomatic myocardial ischemia.Receiver operating characteristic(ROC)curve analysis was performed to evaluate the diagnostic value of individual and combined parameters for asymptomatic myocardial ischemia.Results:Logistic regression showed that LVEF(OR=0.787,95％CI=0.690-0.898,P＜0.001),left ventricular GLS(OR=0.362,95％CI=0.223-0.587,P＜0.001),early systolic lengthening time(OR=1.189,95％CI=1.056-1.338,P=0.004),and left ventricular Tei index(OR=13.317,95％CI=1.007-176.105,P=0.013)were independent predictors for diagnosing asymptomatic myocardial ischemia.Echocardiographic parameters LVEF(area under the curve(AUC)=0.878),left ventricular GLS(AUC=0.892),early systolic lengthening time(AUC=0.836),and left ventricular Tei index(AUC=0.778)all showed good diagnostic efficacy for asymptomatic myocardial ischemia.The combined detection of these parameters achieved an AUC of 0.986,with a sensitivity of 96.84％and specificity of 92.63％.Conclusion:Multi-parameter echocardiography can significantly improve the diagnostic efficacy for asymptomatic myocardial ischemia,aiding in objective assessment and early screening during geriatric outpatient health examinations.关键词
