The chief cause of right heart failure is the increase in blood pressure in the lungs (pulmonary artery). It is present from birth (congenital heart disease). The Social Security Administration (SSA) uses a screening tool called the Listing of Impairments to identify claimants who are so severely impaired that they cannot work at all and thus immediately qualify for benefits. In adults, PH is a common complication of numerous dis-eases, including left -sided heart diseases and chronic lung diseases and/or hypoxia, where PH is associated with exercise limi-tation and a worse prognosis. Capillaries surround the lung alveoli that provide a huge surface area for gaseous exchange – it is here that alveolar diffusion takes place. The truncus anterior sends blood to the right upper lobe (RUL). Cor pulmonale describes a large right ventricle; this part of the heart must work very hard to force blood through stiff and damaged pulmonary arteries. A pulmonary artery is an artery in the pulmonary circulation that carries deoxygenated blood from the right side of the heart to the lungs.The largest pulmonary artery is the main pulmonary artery or pulmonary trunk from the heart, and the smallest ones are the arterioles, which lead to the capillaries that surround the pulmonary alveoli It is one of the most common cardiovascular diseases in the United States.
