title: [The analysis of diagnosis and treatment of inpatients with pulmonary thromboembolism in Beijing].
abstract: OBJECTIVE
  To investigate the clinical characteristics of inpatients with pulmonary thromboembolism (PTE) and the status of its diagnosis and treatment in different hospitals in Beijing.
  
  
  METHODS
  The clinical data of the inpatients with PTE from 18 hospitals with different medical levels in Beijing were retrospectively investigated from July 2011 to June 2012. The demographic characteristics, risk factors, clinical manifestations, diagnosis and treatment were recorded and analyzed.
  
  
  RESULTS
  A total of 206 inpatients with PTE were recruited, of whom 53.4% were males, and the mean age was (72 ± 16) years. In terms of the clinical manifestations, 76.2% patients had dyspnea, and 28.6% had lower limb edema. The diagnosis in 86% patients was confirmed by CTPA and 14% by ventilation perfusion scan. Echocardiography was performed in 74.8% patients, screening for deep vein thrombosis. In 81.1% patients, and BNP or NT-proBNP measurements in 57.8% patients. CTNI was tested in 47.6% patients. All patients received anticoagulant therapy, and 8.25% of the patients received thrombolysis. No cases received secondary thrombolysis therapy. 1.5% of the patients received inferior vena cava filter implantation. The main adverse events were bleeding (4.4%) and liver dysfunction (9.2%). The mortality during hospitalization was 2.9%. Compared with tertiary hospitals, the time from admission to diagnosis was shorter, the proportion of intermediate- and high-risk patients was higher in secondary hospitals and fewer patients received lung ventilation perfusion scan.
  
  
  CONCLUSIONS
  The status of diagnosis and treatment of inpatient with PTE in hospitals of different medical levels in Beijing is relatively satisfactory, while more attention should be paid to the risk stratification and the identification of etiology.
