Pulmonary hypertension (PH) is a rare, but life-threatening, disease which affects the pulmonary arteries, making them become narrowed and thickened. These vessels, which are responsible for transporting blood from the right heart ventricle to the lungs, become obstructed due to the disease, leading to high blood pressure in the lungs. In the long-term, pulmonary hypertension may result in enlargement and weakening of the heart, as well as right heart failure and death.
In some cases, pulmonary hypertension is an idiopathic disease, which means its causes are not fully understood. In other cases, it occurs as a result of other medical conditions. In both cases, it can cause numerous complications. Hypoxia is a condition which occurs when body tissues do not receive enough oxygen to properly function and it is one of the diseases that can cause pulmonary hypertension. Due to the lack of oxygen, it is a life-threatening condition, which can result in damage not only to the heart and lungs, but also to the brain, liver and other organs.
