Pulmonary capillary hemangiomatosis (PCH) is a disease affecting the blood vessels of the lungs, where abnormal capillary proliferation and venous fibrous intimal thickening result in progressive increase in vascular resistance. [1] It is a rare cause of pulmonary hypertension, and occurs predominantly in young adults.
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 ...
The pathophysiology of pulmonary heart disease (cor pulmonale) has always indicated that an increase in right ventricular afterload causes RV failure (pulmonary vasoconstriction, anatomic disruption/pulmonary vascular bed and increased blood viscosity are usually involved [1]), however most of the time, the right ventricle adjusts to an overload in chronic pressure.
People with coronary artery disease, or narrowing of the blood vessels supplying their heart, may develop symptoms such as: Chest pain that often gets worse with stress or physical activity ...
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.
In chronic thromboembolic pulmonary hypertension, or CTEPH (WHO Group IV), the initiating event is thought to be blockage or narrowing of the pulmonary blood vessels with unresolved blood clots; these clots can lead to increased pressure and shear stress in the rest of the pulmonary circulation, precipitating structural changes in the vessel ...
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 medicine: Symptoms
Atherosclerosis in the aorta and other large blood vessels is a common risk factor, [2] both for thromboembolism and cholesterol embolism. The legs and feet are major impact sites for these types. [2] Thus, risk factors for atherosclerosis are risk factors for arterial embolisation as well: advanced age [1] cigarette smoking [1] [2]
