Objective To evaluate the clinical value of Wells score and revised Geneva score in diagnosing pulmonary embolism for emergency patients.Methods Fifty-nine patients with confermed acute pulmonary embolism were predicted consecutively by the two scores, and clinical data were collected and analysed.Results According to Wells score,zero patient had low probability, 52 patients had intermediate probability and 7 patients had high probability, as for revised Geneva score,15 patients had low probability, 45 patients had intermediate probability and 1 was in high probability. 37 patients(6.7%) showed clinical symptoms of dyspnea and 17 patients(28.8%) exhibited syncope. In addition, positive results with SIQⅢTⅢ on ECG were yielded in 18 patients(30.5%), right ventricular enlargement and pulmonary artery hypertension were 18 patients(30.5%),elevated D-Dimer were 52 (88.1%).Conclusions The Wells score is superior to the revised Geneva score in accessing the emergent patients with pulmonary embolism. Wells score combined with ECG, laboratory test and echocardiograghy can raise the rate of accurate diagnosis.
