Application of echocardiography combined with abdominal and peripheral vascular ultrasound in exogenous heart disease
Objective To explore the value of echocardiogram,and abdominal and peripheral vascular ultrasound in the diagnosis of exogenous heart diseases.Methods We selected 87 suspected patients with exogenous heart disease who had undergone echocardiogram examination by using a color Doppler ultrasound diagnostic system.The diagnostic gold standard was CT angiography(CTA)and pathological diagnosis results.The detection of cardiac structural and functional abnormalities was compared between echocardiography(single examination),and echocardiography combined with abdominal and peripheral vascular ultrasound(combined examination).Results There were 60 patients diagnosed with exogenous heart disease with a diagnosis rate of 68.97%.There was no statistically significant difference in the specificity and positive predictive value between single and combined examinations in diagnosing exogenous heart disease(P>0.05).The diagnostic sensitivity,accuracy rate,and negative predictive value of the combined examination were significantly higher than those of single examination(P<0.05).Compared with single examination,the combined examination could significantly improve the detection rate of cardiac structural and functional abnormalities(P<0.05).Conclusion The combined application of echocardiography,and abdominal and peripheral vascular ultrasound in diagnosing exogenous heart diseases helps to accurately diagnose cardiac and exogenous lesions in clinical practice.It could increase diagnosis rate,and reduce the risk of misdiagnosis and missed diagnosis.The combined examination has higher diagnostic efficacy.
