Pulmonary Hypertension

         Basic Facts

  • Hypertension is high blood pressure that persists over time. 
  • Pulmonary hypertension is high blood pressure in the pulmonary arteries, which carry blood from the heart to the lungs, or in the pulmonary veins, which carry blood from the lungs to the heart. 
  • As blood pressure in the pulmonary arteries increases, the right side of the heart must work harder to pump blood into the lungs. 
  • Pulmonary hypertension may be caused when blood backs up behind the left side of the heart and into the lungs because of heart failure or valve disease.
Pulmonary hypertension is chronic, beginning slowly and progressing. There is no cure for pulmonary hypertension, although it may be treated if caused by an underlying condition.
