ABSTRACT
ObjectiveTo seek the approach to the initial diagnosis of pulmonary embolism through analysis and conclusion of the clinical features of pulmonary embolism.MethodsThe high risk factors,clinical manifestation and results of common auxiliary examinations of 23 patients with pulmonary embolism were analyzed retrospectively.ResultsThere were 91.30％(21/23)patients with high risk factors.The common symptoms were dyspnea (91.30％,21/23) and chest tightness (69.57％,16/23 ),while the triad of pulmonary embolism merely accounted for 13.04％ (3/23).And other symptoms included palpitation,chest pain,hemoptysis and syncope,etc.Blood gas analysis indicated that there were hypoxemia and hypocarbia.The positive rate of D-dimer was 91.30％ (21/23).The abnormal rate of electrocardiogram was 91.30％( 21/23 ) and the abnormal rate of echocardiography was 86.96％(20/23).ConclusionAppropriate approach to the initial prognosis can help to establish the diagnosis of patients with suspected pulmonary embolism as early as possible,as well as differentiate other cardiopulmonary diseases.
