Pulmonary embolism; A lung illustration depicting a pulmonary embolism as a thrombus (blood clot) that has travelled from another region of the body, causes occlusion of the pulmonary bronchial artery, leading to arterial thrombosis of the superior and inferior lobes in the left lung: Specialty: Hematology, cardiology, pulmonology, Emergency ...
Lung infarction or pulmonary infarction occurs when an artery to the lung becomes blocked and part of the lung dies. [1] It is most often caused by a pulmonary embolism . Because of the dual blood supply to the lungs from both the bronchial circulation and the pulmonary circulation , this tissue is more resistant to infarction .

A pulmonary embolism is a blood clot that blocks blood flow to an artery in the lungs, according to the Mayo Clinic. The blood clot usually starts in a vein in your leg and travels to your lungs.
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 ...
For people with two or more affected siblings, the highest incidence rate is found among those ≥70 years of age (390 per 100,000 in men and 370 per 100,000 in women), whereas the highest incidence ratios compared to those without affected siblings occurred at much younger ages (ratio of 4.3 among men 20 to 29 years of age and 5.5 among women ...
