Pulmonary Embolism
Pulmonary embolism (PE) is a blockage of an artery in the lungs by a substance that has traveled from another part of the body. It is a serious medical condition that can be potentially life-threatening. PE is most commonly caused by blood clots that begin in the veins in the lower extremities, such as the leg. These clots travel up to the lungs, where they lodge in the tiny blood vessels. This cuts off blood supply to the lungs, leading to chest pain, shortness of breath, and other symptoms. PE is diagnosed through medical imaging (e.g. CT scans), pulmonary function tests, and blood tests. Treatment usually involves anticoagulants to reduce the risk of further clotting, as well as treatments to address the underlying cause. PE is a medical emergency that requires prompt diagnosis and treatment to prevent further complications and death.
