Abstract：Objective The clinical symptoms , signs, risk factors, echocardiography and ECG features of patients with pulmonary embolism were analyzed retrospectively .Methods From January 2013 to July 2015 , in the 474 th Hospital of PLA, 155 cases underwent CT pulmonary angiography ( CTPA) and were diagnosed as pulmonary embolism , record the clini-cal characteristics , risk factors, patient's electrocardiogram , echocardiogram .Result:155 cases of pulmonary embolism pa-tients with an average age (65.8 ±16.0) years old, the common clinical features of dyspnea , cough, chest pain, accounting for 62.58%, respectively, 60.65%, 34.19%.Common signs and symptoms of shortness of breath , heart rate, fever, lower extremity edema, cyanosis, asymmetry, accounted for 52.26%, 29.03%, 28.39%, 21.29%, 18.06%.D-dimer >500μg/L in 131 cases (84.52%).Blood gas analysis:oxygen partial pressure <80 mmHg in 127 cases, carbon dioxide partial pressure <35 mmHg in 47 cases (30.32%), pH>7.45 in 57 cases (36.7%).Blood leukocyte >10 ×109/L in 44 cases (28.39%), platelet >300 ×109/L in 24 cases (15.48%).The ECG and echocardiographic abnormalities including precor-dial T wave inversion, S1QIIITIII, right bundle branch block , right axis deviation accounted for 21.05%, 12.50%, 9.21%and 7.89%, right ventricular enlargement and pulmonary hypertension , respectively accounted for 14.94% and 25.32%. The common risk factors were 70.32%, 34.84%, 15.48%, and 7.10%, respectively for elderly patients with immobiliza-tion, trauma, surgery and deep venous thrombosis .Hospitalized in the respiratory department of 103 cases (66.45%), 10 cases of cardiology department (6.45%), 4 cases (2.58%) in department of Endocrinology , ICU of 5 cases (3.23%), 3 cases of the emergency department (1.94%), surgery (department of general surgery, department of orthopedics, department of Neurosurgery, department of urinary surgery) in 30 cases (19.35%).139 patients ( n =10) were treated with intrave-nous thrombolytic therapy (89.68%), and thrombectomy was performed in 2 patients (1.29%).3 cases (1.94%) died in hospital .4 cases gave up treatment .Conclusion The clinical features of patients with pulmonary embolism , lack of specifici-ty, should be differentiated from patients with pulmonary heart disease , risk factors, electrocardiogram and echocardiography changes contribute to the diagnosis of pulmonary embolism , and given anticoagulant or thrombolytic therapy as soon as possi-ble, reduce the mortality of patients .
