Abstract:
Objective Prognostic value of cardiac troponin T,echocardiography and ECG in patients with confirmed pulmonary embolism were evaluated. Methods 105 consecutive patients with confirmed PE were enrolled in this retrospective study. PE was confirmed by pulmonary angiography,lung scan or echocardiography and subsidiary analyses, cTnT was measured within 24 hours after admission. ECG and ECHO were recorded within 24 hours after admission. Results ECG signs of acute right ventricular strain are not predictors of mortality and severe complications in patients with confirmed PE. Only right ventricular dilation but not pulmonary hypertension detected at echocardiography in patients with acute PE is an independent risk factor for fatal outcome. There were significant differences in right ventricular dysfunction,massive PE and severe complications between the troponin-positive group and the troponin-negative group. In logistic regression analysis,cTnT is an independent predictor of severe complications. Furthermore,high cTnT was significantly associated with severe PE. Conclusion Right ventricular function is an important prognostic factor for pulmonary embolism. Echocardiographically detected right ventricular dysfunction can be used to assess the prognosis of PE. Elevation of cTnT was significantly associated with right ventricular dysfunction,and can be used to assess the prognosis of PE. ECG signs of acute right ventricular strain were not specific, so can not be used to assess the prognosis of PE.
