The Full Form of PAH is Pulmonary arterial hypertension.

PAH is the medical abbreviation for pulmonary arterial hypertension. PAH is a specific type of high blood pressure that affects your heart and lungs. When you have PAH, the blood vessels in your lungs become narrower. This means your heart has to work harder to pump blood to your lungs.

PAH is progressive, it worsens over time, and it’s eventually fatal. But it can be treated with medication, so people with PAH can address their symptoms and possibly live longer.
