Pulmonary Hypertension Causes in Humans
The first factor of pulmonary hypertension causes in humans that is, the heart has two shafts (atria) and two chambers (the ventricles) that pass through the blood and through the body. Before being restored to other body parts, the right ventricle of the heart pumps blood into the lungs through the pulmonary arteries (lungs) to release carbon dioxide and transport oxygen. In good body condition, blood can flow easily through blood vessels in the lungs. However, in cases of pulmonary hypertension, there is a change in the blood vessels in the lungs so that blood and oxygen can not flow properly.
Pulmonary hypertension is caused by the occurrence of narrowing, blockage, or damage to small blood vessels and capillaries that trigger increased blood pressure in the vessels. High blood pressure then makes the blood vessel wall becomes thick, stiff, inflamed, tense, or trigger the growth of additional tissue that leads to reduced blood flow. Pulmonary hypertension can be caused by some of the following conditions:
- Group 1: Pulmonary arterial hypertension. Also known as idiopathic pulmonary arterial hypertension, a sustained increase in pressure in the lung vessels of unknown cause. Some conditions are suspected to trigger this condition, among other genetic mutations that are down-and-down in the family, methamphetamine drugs, and congenital heart disease.
- Group 2: Pulmonary hypertension caused by left heart disease, such as various types of left heart valve disease and impairment or failure of function in the left ventricle of the heart.
- Group 3: Pulmonary hypertension caused by lung disease. Some disorders experienced by the lungs can lead to increased blood pressure, such as chronic obstructive pulmonary disease (emphysema), sleep disorders (sleep apnea), and pulmonary fibrosis. A person who has lived in the highlands for too long is also at risk of developing pulmonary hypertension.
- Group 4: Pulmonary hypertension caused by chronic blood clots in the lungs or chronic thromboembolic pulmonary hypertension.
- Group 5: Pulmonary hypertension caused by other related conditions are also unknown causes, such as blood disorders, metabolic disorders, and tumors that suppress the lung arteries. Disorders that affect the function of other organs can also trigger pulmonary hypertension, such as sarcoidosis.
Pulmonary hypertension can also occur in newborns. This condition can be attributed to the lung condition of the infant who is not well developed at birth (severe pulmonary hypoplasia). Other conditions that may be associated are hypoglycemia, sepsis, and meconium aspiration syndrome or newborns who inhale placental fluid or the baby’s droppings (meconium).
Another cause of pulmonary hypertension is Eisenmenger syndrome. This condition is one type of congenital heart disease that is generally caused by a large hole between the two chambers of the heart. Eisenmenger’s syndrome causes oxygen-containing blood to mix with oxygen-free blood and then back to the lungs that should be flushed throughout the body. This condition puts blood pressure on the lung vasculature up, triggering pulmonary hypertension.
In addition to being triggered by impaired health conditions, pulmonary hypertension may also be triggered by several risk factors:
- The history of the disease in the family history
- Use of illegal drugs
- Consume appetite suppressant drugs
- The case of arterial pulmonary arterial pulmonary hypertension is commonly found in adolescent adolescents
- Have one of the above mentioned health conditions or other health problems
- Living in the highlands
