When looking at all cases, the rate of fatal pulmonary emboli has declined from 6% to 2% over the last 25 years in the United States. [109] In Europe, an average of approximately 40,000 deaths per year with pulmonary embolism as the primary cause was reported between 2013 and 2015, a conservative estimate because of potential underdiagnosis.

ATE can cause life-threatening conditions, such as stroke, myocardial infarction, acute kidney injury, limb ischemia, and mesenteric ischemia. ATE is usually caused by atherosclerosis , which leads to plaque rupture and thrombus formation, or by cardioembolism, which results from the embolization of a cardiac thrombus, such as in atrial ...
The main causes of thrombosis are given in Virchow's triad which lists thrombophilia, endothelial cell injury, and disturbed blood flow. Generally speaking the risk for thrombosis increases over the life course of individuals, depending on life style factors like smoking, diet, and physical activity, the presence of other diseases like cancer ...
This carries a risk of bleeding and is therefore reserved for those who have a form of thrombosis that may cause major complications. In pulmonary embolism, this applies in situations where heart function is compromised due to lack of blood flow through the lungs ("massive" or "high risk" pulmonary embolism), leading to low blood pressure. [42]
Arterial embolism can cause occlusion in any part of the body. It is a major cause of infarction (tissue death from blockage of the blood supply). [4] An embolus lodging in the brain from either the heart or a carotid artery will most likely be the cause of a stroke due to ischemia. [5]
Normally, the pulmonary artery supplies oxygen-filled blood from the lungs to the heart. But with this condition, the arteries are blocked, narrowed, or even destroyed, preventing healthy blood flow.
Chronic thromboembolic pulmonary hypertension (CTEPH) is a long-term disease caused by a blockage in the blood vessels that deliver blood from the heart to the lungs (the pulmonary arterial tree). These blockages cause increased resistance to flow in the pulmonary arterial tree which in turn leads to rise in pressure in these arteries ...
Embolization refers to the passage and lodging of an embolus within the bloodstream. It may be of natural origin (pathological), in which sense it is also called embolism, for example a pulmonary embolism; or it may be artificially induced (therapeutic), as a hemostatic treatment for bleeding or as a treatment for some types of cancer by deliberately blocking blood vessels to starve the tumor ...
