Pulmonary arterial hypertension (PAH) also known as pulmonary hypertension is high pressure in the blood vessels that carry blood from your heart to your lungs. This increased pressure in the blood vessels of the lungs will make your heart work harder to pump blood into the lungs. The common symptoms as shortness of breath, chest pain, and lightheadedness. If left untreated then it will cause damage to the heart.
