What is idiopathic pulmonary arterial hypertension?

Answer 1

Primary pulmonary hypertension is generally classified as a disease of the lung, related to high blood-pressure. Essentially, the increased pressure causes some pulmonary arteries and veins to work at drastically different rates than others, creating an imbalance that can cause fatigue, shortness of breath, fainting, and a persistent cough.

Answer 2

Secondary pulmonary hypertension is increased pressure of the blood vessels of the lungs as a result of other medical conditions.

Answer 3

Pulmonary arterial hypertension refers to an elevated blood pressure in the pulmonary circulation. Although the cause is often unknown, one common cause is emphysema.

Answer 4

The cause for Primary Pulmonary Hypertension(PPH) is a buildup of smooth muscle cells that line the arteries. The underlying cause of the disease may be genetics.
