Abstract：Objective To analyze the clinical features of the patients who death due to acute pulmonary embolism and discuss the early assessment method of high risk patients with pulmonary embolism.Methods From June 1997 to December 2010,31 cases suffered acute pulmonary embolism and eventual death.The clinical features of these patients were retrospectively analyzed.Results The time from onset to death of 31 patients were 2 hours to lldays.In these patients,29.1％ associated with COPD,51.6％ with hypertension,35.5％ with coronary heart disease,25.8％ with type 2 diabetes,16.1％ with cerebral infarction,and 51.6％ with lung infection.7 patients suffered respiratory and cardiac arrest.The most common symptoms were shortness of breath (24 cases,77.4％ ).The blood pressure of 77.4％ patients dropped in the initial onset.In D-dimer test,90.3％ patients' is over ＞500 μg/ml.In the indicators of serum enzymes,LDH of the 61.3％ patients increased,cTNI of 32.3％ patients increased,and AST of the 19.4％ patients increased.The ECG of 48.4％ patients appeared QⅢTⅢSⅠ features,also 48.4％ patients showed only QⅢ or SI features.In the patients with respiratory and cardiac arrest,the initial ECG in 5 cases appeared ventricular escape beat.In 5 cases of patients surviving more than 3 days,the UCG showed the performance of right ventricular dysfunction.Conclusion In the patients death due to acute pulmonary embolism,the mostcommon characters were shortness of breath,low blood pressure and QⅢTⅢSⅠ/QⅢ/SⅠ in ECG.The prognosis of them was poor.Rational use of simple bedside examination methods was very important to early identification of high-risk patients and assessing prognosis.
