Causes, Symptoms and Treatment of Primary Pulmonary Hypertension
PAH or pulmonary arterial hypertension is also known as primary pulmonary hypertension. It is a very rare hypertension disease that affects your capillaries and arteries. The blood from the right ventricles of your heart flows into your lungs through these vessels. When the pressure in your arteries arises, your heart has to work much harder to pump the blood and as a result, it weakens the heart muscles.
