Pulmonary arterial hypertension is continuous high blood pressure in the pulmonary artery. The pulmonary artery carries blood from the right side of the heart to small arteries in the lungs.

In Pulmonary arterial hypertension, the arterial walls tighten, thicken, and scar. This leads to narrowing of the artery. In addition, tiny blood clots may cause blockage of blood flow.

All of these changes cause the right side of the heart to work harder to pump blood to the lungs. Over time, the heart weakens and cannot pump blood adequately. This may lead to right heart failure.

Although there is no cure for Pulmonary arterial hypertension, many treatment options are available. Treatment is based on the specific problem causing your condition. Medications that relax and open up the arteries to allow better circulation:

• Tracleer® (bosentan)
• Flolan® (epoprostenol)
• Remodulin® (treprostinil)
• Revatio® (sildenafil)

Additional treatments may include anticoagulants (blood thinners), calcium channel blockers, and digitalis.

Diuretics (fluid pills) and oxygen are often used to relieve symptoms. Surgery is indicated only when required for removal of blood clots or, in severe cases, for lung or heart-lung transplant.
