A pulmonary embolism affects as many as 5 out of 10,000 people in the U.S. each year, and sudden death can occur as a result of pulmonary embolism. The risk factors include prolonged bed rest or inactivity, oral contraceptive use, surgery, child birth, cancer , stroke , heart attack , heart surgery, and fractures of the hips or femur. Other clot-preventive measures include leg exercises and elastic support stockings as appropriate. An ECG may show abnormalities caused by strain on the heart. Definitive treatment consists of dissolving the clot by thrombolytic therapy.
Anticoagulant therapy is preventive by inhibiting further clot formation.
Oxygen therapy is required to maintain normal oxygen concentrations until the acute injury to the lungs has resolved. Surgery in patients at great risk for recurrent embolism is sometimes indicated.
