pulmonary hypertension

Pulmonary hypertension is abnormally high blood pressure in the arteries of the lungs.  It is characterized by a narrowing of the small arteries of the lung, which makes it hard for blood to flow.


Symptoms may include:


  • chest pain
  • dizziness
  • fainting
  • fatigue
  • leg swelling
  • light-headedness during exercise
  • shortness of breath during activity
  • weakness

Causes may include:


  • a genetic defect
  • certain diet medications
  • history of a blood clot in the lung
  • lung or heart valve disease
  • obstructive sleep apnea

In some cases, the cause is unknown.  If it occurs without a known cause, it is called primary pulmonary hypertension. If it is caused by a medicine or medical condition, it is called secondary pulmonary hypertension.  Primary pulmonary hypertension is rare.


There is no known cure. The goal of treatment is to control symptoms.

Treatment may include:


  • medication
