Abstract：Objective:To investigate the effect of cardiac troponin T( cTnT)and heart colour to exceed its significance in evaluating the prognosis of acute pulmonary embolism,and timely and accurate diagnosis and treatment of patients with pulmo-nary embolism,to improve the prognosis of patients and improve the survival rate. Methods:52 cases with pulmonary embolism between January 2010 in December 2013 by our institute of respiratory diseases diagnosis of,all of the patients in the hospital after electrocardiogram( ECG),myocardial troponin( cTnT)and heart colour to exceed check,the data to evaluate the clinical value in prognosis of acute pulmonary embolism. Results:The ECG in acute pulmonary embolism without important clinical val-ue in the evaluation of prognosis. supersonic and enchanted the graph is observed end—diastolic right ventricular diameter in-creased pulmonary embolism risk factor for severe or life—threatening complications,pulmonary artery pressure was not found is important index for prognosis of pulmonary embolism. Positive and negative patients right heart function obstacle massive pul-monary embolism were significant difference of serious complications,multiple regression analysis showed that positive troponin T is pulmonary embolism risk index of the severe complications. Conclusion:Right heart function is one of the important param-eters determine the prognosis of acute pulmonary embolism,the detection of right heart function is through the heart colour to exceed to reflect the prognosis of acute pulmonary embolism. Right heart function to a certain extent,related to the cardiac tro-ponin T,can evaluate the prognosis of acute pulmonary embolism. Electrocardiogram( ecg)in the right reaction specificity on heart function is poor,little clinical value to assess the prognosis of acute pulmonary embolism.
