Clinical value of MRI,blood culture,and transthoracic echocardiography in diagnosis of infective endocarditis
Objective
To explore the clinical value of MRI, blood culture, and transthoracic cardiac ultrasound in the diagnosis of infective endocarditis (IE).
Methods
134 IE patients admitted to our hospital from January, 2016 to June, 2018 were retrospectively selected as the study objects. All the patients had the data of MRI, blood culture, and transthoracic ultrasound diagnosis as well as of prognosis. The detection rates of vegetations of different sizes and different locations by MRI and the chest cardiac ultrasound were observed. The pathogenic bacteria distribution characteristics of blood culture were analyzed. The diagnostic accuracies of the three methods were compared.
Results
The detection rate of transthoracic echocardiography was 93.28%, and was significantly higher than that of MRI (72.39%; P<0.05). The detection rate of transthoracic echocardiography for vegetation less than 5 mm was 27.61%, and was significantly higher than that of MRI (11.94%; P<0.05). The detection rates of aortic and pulmonary valve vegetations by transthoracic echocardiography were 14.93% and 11.94%, respectively, which were significantly higher than those of MRI (5.97% and 2.99%; both P<0.05). In blood culture examination, the detection rate of pathogens was 61.19%; Gram-positive bacteria were the main pathogens, accounting for 53.66%. The combined diagnostic accuracy of the three methods was 98.51%, which was significantly higher than those of transthoracic echocardiography, MRI, and blood culture (93.28%, 72.39%, and 61.19%; all P<0.05).
Conclusion
The application of MRI and blood culture combined with transthoracic electrocardiogram for IE patients has improved the detection rate of vegetation sites and provided more information on cardiac function and pathogenic microorganisms, and helped clinicians to develop more effective interventions.
