Clinical analysis of acute pulmonary embolism in 47 cases

Objective To analyze the risk factors,clinical features,misdiagnosis and the treatment methods of acute pulmonary embolism (APE),in order to improve the diagnosis rate and the prognosis.Methods A total of 47 APE patients diagnosed from January 2009 to December 2012 were studied.The risk factors,clinical manifestation,laboratory examination,the misdiagnosis reasons and treatment were analyzed,and the patients were divided into two groups according to the onset time,the time of diagnosis and the prognosis of the two groups was compared.Results APE can be easily misdiagnosised for the diversified clinical manifestations; the lack of specific test results and ECG,misdiagnosed cases of heart failure in 10 cases (21.3％),pulmonary infection in 8 cases (17.0％),the ACS in 7 cases (14.9％),cerebral infarction in 2 cases (4.3％),missed diagnosis in 1 case (2.1％),the revised Geneva score was used to evaluate patients,the early diagnosis rate was improved obviously.Conclusions APE can be complicated with many diseases,and the clinical manifestation is diversified,so it can be easily misdiagnosed,filtering potential patients by revised Geneva score can improve the early diagnosis rate.
