Alerts and Notices
Synopsis
The clinical presentation depends upon the size, location, number and chronicity of emboli, and the patient's cardiorespiratory reserve. Features include dyspnea and tachypnea, pleuritic chest pain, cough, hemoptysis, pleural effusion, pulmonary infiltrates, cyanosis, syncope, and, in some cases, sudden death (classically pulseless electrical activity [PEA] arrest).
Predisposing factors for PE include history of venous thromboembolism, embolization of struts from inferior vena cava filter, genetic predilection (Factor V Leiden, anti-thrombin III gene mutation, protein C or S deficiency, etc), cancer, trauma, surgery, pregnancy or oral contraceptive use, prolonged immobility, advanced age, obesity, and congestive heart failure.
