Pathophysiology of Pulmonary Arterial Hypertension


Pulmonary hypertension (PH) is a rare lung disease that refers to an increase in blood pressure in the pulmonary arteries. According to the WHO (World Health Organization) there are 5 different groups of PH and pulmonary arterial hypertension (PAH) belongs to the group 1.

PAH is characterized by abnormally high blood pressure (hypertension) in the pulmonary artery – this artery carries blood from the heart (right ventricle) to the lungs.

In this video, shared by DiagnosisPAH in 2013, an educational overview of three principal pathways—endothelin, nitric oxide, and prostacyclin—involved in the pathogenesis of pulmonary arterial hypertension is discussed, with a very well made 3D animation, which explains every detail about this heart and lung condition, as well as its symptoms, and what happens to the patient’s body among other useful information.

Learn more about pulmonary arterial hypertension with a pulmonologist.
