Pulmonary embolism is the third leading cause of death from cardiovascular disease and happens when blood clots block an artery in the lungs, so blood and gas cannot flow normally.
Even when a blood vessel is not injured, blood clots may form in the body under certain conditions. A clot, or a piece of the clot, that breaks free and begins to travel around the body is known as an embolus. [1] [2] Thrombosis may occur in veins (venous thrombosis) or in arteries (arterial thrombosis).
A pulmonary embolism (PE) occurs when a blood clot from a deep vein (a DVT) detaches from a vein , travels through the right side of the heart, and becomes lodged as an embolus in a pulmonary artery that supplies deoxygenated blood to the lungs for oxygenation. [28] Up to one-fourth of PE cases are thought to result in sudden death. [12]

Sometimes, pulmonary embolism is classified as arterial embolism as well, [2] in the sense that the clot follows the pulmonary artery carrying deoxygenated blood away from the heart. However, pulmonary embolism is generally classified as a form of venous embolism, because the embolus forms in veins.
Venous thrombosis is the blockage of a vein caused by a thrombus (blood clot). A common form of venous thrombosis is deep vein thrombosis (DVT), when a blood clot forms in the deep veins. If a thrombus breaks off and flows to the lungs to lodge there, it becomes a pulmonary embolism (PE), a blood clot in the
