Acute pulmonary embolism (PE) is a severe and potentially fatal disease with a mortality rate of approximately 30% if untreated. The incidence is 2 per 1,000 person years in the Western countries. PE is a blockage of the main pulmonary artery or one of its branches by a thrombus, typically a blood clot from the deep veins of the lower extremities. PE reduces the cross-sectional area of the pulmonary blood vessels, resulting in an increase in total pulmonary vascular resistance and pulmonary hypertension.
