Abstract：Objective To explore the correlated risk factors of pulmonary embolism (PE) in the aged, and provide preventive measures for PE.Methods Eighty old people with PE were retrospectively selected as the case group, and 80 aged people without PE were randomly selected as the control group. All the patients were carried out a retrospective survey. The methods of χ2 test and multiple logistic regression were used to screen the risk factors of PE in the aged.Results According to the sorting result of OR value, multiple logistic regression method showed that the risk factors of PE in the age included DVT (OR=5.436), Malignant tumor (OR=4.221), trauma and surgery (OR=3.931), COPD (OR=3.529), atrial fibrillation (OR=3.114) and bone fracture (OR=2.266).Conclusion The causes and risk factors of PE in elderly patients are very complicated. Risk factors for elderly patients should be early evaluated, in order to take precautions and treatment measures early, to cut down the incidence rate of PE in the aged, and improve the prognosis of PE patients.
