Familial primary pulmonary arterial hypertension (PAH), is also known as pulmonary hypertension. It is a hereditary type of hypertension in the lungs that affects your pulmonary blood vessels. These blood vessels convey blood from the lower right of your heart (right ventricle) into your lungs.
As the weight in your pulmonary blood vessels and capillaries increase, your heart must work harder to siphon blood to your lungs. After some time, this tires out your heart muscle. In the long run, it can prompt heart problems and death.
There is no known solution for PAH, yet treatment alternatives are there. If you have PAH, treatment may help calm your side effects, bring down your risks of having complications, and save you from death.
