Video - Pulmonary hypertension

Pulmonary hypertension (PH) is a condition characterized by an increase in blood pressure in the pulmonary artery, pulmonary vein, or pulmonary capillaries. It can be due to left heart disease, chronic lung disease, or other conditions that specifically cause pulmonary arterial hypertension. Regardless of the cause, it can complicate right-sided heart failure, what's referred to as cor pulmonale. Symptoms of PH include shortness of breath, dizziness, fainting, and leg swelling. Treatment focuses on the underlying cause and may include supplemental oxygen, and medications like endothelin receptor antagonists and prostacyclins.
