Pulmonary Hypertension, An Issue of Heart Failure Clinics

Pulmonary hypertension (PH) is increased pressure in the pulmonary arteries, which carry blood from the heart to the lungs to pick up oxygen.  The changes resulting from PH make it difficult for the heart to push blood through the pulmonary arteries, causing the heart to become weak and possibly to develop failure.  Understanding the causes and treatment of PH can help heart failure specialists prevent heart failure due to PH.
