title: [Clinical analysis of 252 patients with pulmonary thromboembolism].
abstract: OBJECTIVE
  To improve the capability of diagnosing and treating for pulmonary thromboembolism (PE) by analyzing the characteristics of PE.
  
  
  METHODS
  Retrospective analysis was performed among 252 patients with PE, diagnosed by CT pulmonary angiography (CTPA) without medical history of serious cardiopulmonary disease. And the before-after comparisons in echocardiography cardiovascular parameters and pulmonary artery Qanadli embolism index (PAQI) were launched within 32 patients who finished 3 months follow-up visiting.
  
  
  RESULTS
  In 252 patients with final diagnosis of PE, smoking was the most important risk factor, accounted for 44.84%. Dyspnea was the main symptom in patients with PE (84.13%). PE often occurred in the elderly [64.00 (19.75) years old]. Hypotension, shortness of breath and tachycardia were always observed when circulatory collapsed. It could not be excluded for PE when D-dimmer was less than 5000 mg/L. In 32 patients rechecked 3 months after treatment, PAQI was significantly decreased compared with that before treatment [0.05 (0.18) vs. 0.39 (0.44), P < 0.01], but there were no significant differences in cardiovascular parameters before and after treatment.
  
  
  CONCLUSIONS
  The clinical manifestations of PE are variable, it could be considered when the elder or smoker were suffered with dyspnea. After 3 months of anticoagulant therapy, cardiac morphology induced by PE didn't get demonstrate improvement.
