  • Bedside Echocardiography in the Diagnosis of Patients with Suspected Pulmonary Embolism

    ObjectiveTo explore the diagnostic value of the bedside echocardiogram for different risk stratification of patients with suspected pulmonary embolism. MethodsPatients with suspected pulmonary embolism in the emergency department of the Second Afflicted Hospital Xi'an Jiaotong University between July 2013 to December 2015 were included. According the Wells scores, they were divided into a low risk group (0-2 points), a intermediate risk group (3-6 points) and a high risk group (>6 points). All patients were underwent the bedside echocardiogram diagnosis, and the diagnostic value of the echocardiography for pulmonary embolism, the characteristics of different risk stratification of patients were analyzed by SPSS 18.0 software. Results115 patients with suspected pulmonary embolism were included, of which 20 were in the low risk group, 73 were in the medium risk group, and 22 were in the high risk group. The incidence of pulmonary embolism among the three groups was significantly different (high-risk vs. medium risk vs. low-risk: 90.9% vs. 76.7% vs. 15.0%, P<0.05), and the higher Wells scores gets, the greater possibility of having the pulmonary embolism. For the intermediate-risk group, the incidence of pulmonary embolism was significantly higher in patients with positive ultrasonic results than those with the negative ultrasonic results (87.3% vs. 44.4%, P<0.05). The predication of the ultrasonic positive and the negative in the low and high risk groups had no statistical differences (P>0.05). The result of echocardiogram showed that the right ventricular end-diastolic diameter, right ventricular end-diastolic transverse diameter, right atrial end-diastolic transverse diameter, RV/LV, RA/LA in the high risk group and the intermediate risk group were significantly higher than those in the low risk group (all P values <0.05). The right ventricular anterior wall activity in the low risk group was higher than that in the high risk group (P<0.05), but this difference was not found between the high risk group and the intermediate risk group. ConclusionBedside echocardiogram can be used as the diagnosis and differential diagnosis methods of suspected pulmonary embolism, and it has relatively higher diagnostic value for intermediate to high risk patients predicted by the Wells scores than low risk ones.
