    Pulmonary Hypertension

    Pulmonary hypertension is high pressure in the blood vessels that carry blood into the lungs. This strains the lungs and heart. It can lead to serious problems.

    High blood pressure

    Systemic hypertension means the pressure is too high in blood vessels all throughout the body. A person with pulmonary hypertension may also have high blood pressure throughout the body.

    What causes pulmonary hypertension?

    The cause is sometimes not known. But it's most often caused by another health problem. In many cases, controlling this problem can help prevent or control pulmonary hypertension. Some of the most common causes of pulmonary hypertension are below.

    In children:

    • Severe lung problems in a newborn

    • Lung conditions, such as cystic fibrosis or interstitial lung disease

    • Congenital heart defects

    • Other conditions, such as scleroderma, lupus, or sickle cell disease

    • Genetic disease

    In adults:

    • Lung conditions, such as chronic obstructive pulmonary disease (COPD), advanced bronchitis, cystic fibrosis, or pulmonary fibrosis

    • Liver disease

    • Blood clots in the lungs

    • Left-sided heart failure

    • Sleep apnea

    • Other conditions, such as scleroderma, lupus, or sickle cell disease

    • Some medicines

    • Genetic disease

    What are the symptoms of pulmonary hypertension?

    Symptoms may come on suddenly. Or, they may come on slowly over time. Symptoms can include:

    • Shortness of breath

    • Blue lips or fingernails (signs of low oxygen)

    • Tiring quickly, especially when active

    • Fast heartbeat

    • Pain in the upper right side of the abdomen

    • Swelling in the legs or ankles

    • Chest pain or pressure

    • Fainting or dizzy spells

    How is pulmonary hypertension diagnosed?

    Your healthcare provider will give you an exam. They will listen to your heart and lungs. They will measure your blood pressure. You may have tests such as:

    • Blood tests. These measure certain body functions. They also check for problems such as infection.

    • Chest X-ray. This takes a picture of the inside of the chest. It can show some heart and lung problems.

    • Electrocardiogram (ECG). This test records the heart’s electrical activity.

    • Echocardiogram (echo). This test uses sound waves to create a moving picture of the heart.

    • Pulmonary function tests. These tests measure breathing and lung capacity.

    • Perfusion lung scan. This scan may be used to find changes in the arteries that lead to the lungs. It can show blood flow inside the lungs. And it can show blood clots.

    • CT scan of the chest. This test takes detailed pictures of the lungs.

    • 6-minute walk test. This test measures your exercise tolerance. It checks if your oxygen levels drop when you exert yourself.

    • Right heart catheterization (cath). This procedure measures pressures in the heart and lungs. It’s the only test that measures the pressure inside the pulmonary arteries. A thin tube (catheter) is put into a blood vessel in the groin or neck. It's guided into the right side of the heart and to the pulmonary artery. This is the main artery that sends blood to your lungs. Blood pressure tests are then done.

    How is pulmonary hypertension treated? 

    Treatment depends on your age, health, and how bad your symptoms are. Any underlying health problems you have will be treated. Treatment may also include:

    • Oxygen

    • Medicine to lower the pressure in the lung blood vessels

    • Medicine to help the body lose excess water

    • Medicine to prevent blood clots

    • Medicine that helps the heart beat stronger, pump more blood, and control abnormal heart rhythms

    What are the long-term concerns?

    Pulmonary hypertension has no cure. But some treatments may relieve symptoms and slow the progression of the disease. In rare and severe cases, a lung transplant may be needed. Your healthcare provider can tell you more about this if needed.
