Occurring naturally as predominantly the trans isomer, it gives cinnamon its flavor and odor. [1] It is a phenylpropanoid that is naturally synthesized by the shikimate pathway. [2] This pale yellow, viscous liquid occurs in the bark of cinnamon trees and other species of the genus Cinnamomum. It is an essential oil. The bark of cinnamon tree ...
This is an incomplete list, which may never be able to satisfy certain standards for completion.. There are many conditions of or affecting the human circulatory system — the biological system that includes the pumping and channeling of blood to and from the body and lungs with heart, blood and blood vessels.
Pulmonary heart disease, also known as cor pulmonale, is the enlargement and failure of the right ventricle of the heart as a response to increased vascular resistance (such as from pulmonic stenosis) or high blood pressure in the lungs. [2] Chronic pulmonary heart disease usually results in right ventricular hypertrophy (RVH), [4] whereas ...
In those with underlying heart or lung disease, effective control of congestive and respiratory symptoms can help prevent pulmonary edema. [37] Dexamethasone is in widespread use for the prevention of high altitude pulmonary edema. Sildenafil is used as a preventive treatment for altitude-induced pulmonary edema and pulmonary hypertension.
Lung transplantation is the only therapeutic option available in severe cases. A lung transplant can improve the patient's quality of life. [30] Immunosuppressive drugs can also be considered. These are sometimes prescribed to slow the processes that lead to fibrosis. Some types of lung fibrosis respond to corticosteroids, such as prednisone. [29]
Pathogenesis in pulmonary hypertension due to left heart disease (WHO Group II) is completely different in that constriction or damage to the pulmonary blood vessels is not the issue. Instead, the left heart fails to pump blood efficiently, leading to pooling of blood in the lungs and back pressure within the pulmonary system.

Echocardiography to evaluate heart function. Echocardiography is the preferred choice for diagnosis of heart failure in patients. [1] [2] As well as evaluation of lung function via: Pulmonary function testing (PFT) complete with bronchoprovocation testing. PFTs represent the preferred method for evaluating for bronchial asthma.
