What is Pulmonary Arterial Hypertension? Leave a comment

When the pulmonary artery becomes blocked due to a build-up of plaque, the left ventricle cannot fill properly. This leads to an increased workload on the right ventricle, which then begins to fail. This causes high blood pressure in both the pulmonary arteries and the systemic arteries.


  • When there is no oxygen in the body, the backup of oxygenated (oxygenated) red cells returns the oxygen into the bloodstream.
  • Greater pressure on the right ventricle pushes blood through the lungs.


If you’re experiencing an increased blood flow through the lungs, you need to see a doctor immediately. There are three different forms of pulmonary hypertension, including hereditary, idiopathic, and associated pulmonary hypertensive syndromes.

Persistent pulmonary hypertension of the newborn (PPHN) is a type of pulmonary arterial hypertension that occurs during the first week after birth. It is caused by an inability of the blood vessels to expand properly in response to high levels of carbon dioxide in the blood. When the baby isn’t born, he gets his oxygen from the umbilicus and placenta. If there is no improvement in the baby’s health after 48 hours, then the doctor may perform surgery to open up the ductus arteriosus, allowing the baby’s heart to pump more blood through the body.

What Does Pulmonary Heart Disease Feel Like?

Pulmonary Arterial Hypertension (PAH) is a chronic condition that develops slowly but worsens over time. Because PAH doesn’t usually cause obvious health issues until later, people often don’t realize they have it. Commonly reported PAH symptoms include:- 

  • Fatigue
  • Weakness
  • Dizziness
  • Chest Pain
  • Unconsciousness
  • Rapid heart rate
  • Shortness of breath
  • Swelling in the ankle and legs

Most patients ignore these symptoms until they get worse. However, if the condition becomes severe enough, the symptoms may become so bad that they could affect one’s life.

What causes pulmonary hypertension?

Pulmonary arterial hypertension (PAH) usually occurs when there are too many blood vessels in the lungs. These blood vessels get clogged up and narrow down, which makes them harder to breathe through. Several things may cause this condition. They include:

  1. Connective tissue diseases:-

For lupus, medicines include hydroxychloroquine (Plaquenil), hydroquinone (hydroxyquinoline) 400 mg, hydroquinone sulfate

  1. HIV:-

HIV is a common name for Human Immunodeficiency Virus, which is also known as Hiv. It is a virus that can cause Acquire Immune Deficiency Syndrome. It is a disease that weakens your body’s ability to fight off diseases. It attacks cells that help make antibodies against viruses and bacteria. Antibodies are proteins made by white blood cells called B lymphocytes. They protect us from germs such as colds, flu, and pneumonia. When we get sick, our bodies produce these antibodies to fight off the germs. However, if someone gets infected with HIV, they may not make enough antibodies to fight off the virus. This means that the person becomes susceptible to getting sick again.

You may want to consider taking some common prescription medications for HIV infection, including Lamivir (150 mg), Lamivir (100 mg), Lamivir HBV (30 mg), etc.

  1. Liver diseases:-

Several factors can cause cirrhosis, including alcohol abuse, hepatitis C infection, and autoimmune disorders such as primary biliary cirrhosis (PBC). PBC causes inflammation of the small intestine, leading to increased levels of bilirubin in the bloodstream. Bilirubin is an enzyme found in the skin, muscles, brain, and intestines. When too much bilirubin accumulates in the body, it may lead to jaundice.

  1. Use of illicit drugs:-

Pulmonary arterial hypertension (PAH) may occur due to the use of certain types of illegal drugs. Though the exact mechanism by which these substances cause PAH is not known, they should be avoided.

What is the Best Treatment for Pulmonary Hypertension?

PAH is not curable, but it can be managed through medication and lifestyle changes. Patients must see a physician regularly to monitor their condition and adjust medications accordingly. Some patients find relief from certain medications once they’ve made the change to healthier habits. 

  • Inhaled medicine
  • Oxygen therapy
  • Heart and lung surgery
  • Medicine administered intravenously
  • Diuretic medicine for reducing swelling in the foot

These drugs help relax the muscles of the arteries in the lung, which reduces the pressure on the heart. They’re often prescribed for people who suffer from pulmonary arterial hypertension.

When PAH occurs because of an underlying medical condition, then treatments are prioritized according to their effectiveness. For instance, if medications fail to control pulmonary hypertension and lower the blood pressure in the lungs, then surgery might be considered.

Can Pulmonary Arterial Hypertension Be Cured?

Pulmonary Arterial Hypertension (PAH) is a chronic condition characterized by high blood pressure in the lungs’ small blood vessels. It causes the thickening and narrowing of these blood vessels which leads to increased resistance to blood flow. As a result, oxygenated blood cannot reach the lungs and they become stiffer and less elastic. Untreated, PAH can cause severe complications including right ventricular dysfunction, cor pulmonale, and death.


Though not all cases can be prevented, by adopting healthy habits, one can lower the risks of developing severe symptoms. Treatment options for pulmonary arterial hypertensión (PAH) may differ from person to person. Consult your doctor to determine the best course of action for you.
