What happens to your body if you have pulmonary arterial hypertension (PAH)?

ANSWER

Your heart pumps blood through your arteries and veins, sending oxygen to all parts of your body. In a single heartbeat, the left side of your heart sends the blood out, and blood also returns to the right side. The right side sends it through the pulmonary artery to the lungs, where it swaps carbon dioxide for oxygen. The blood goes back to the left side of the heart, and the process starts again with the next heartbeat.

It’s a short distance from your heart to your lungs. So normally, the right side doesn’t have to pump very hard. But when you have pulmonary arterial hypertension (PAH), blood doesn’t move freely through the arteries in your lungs. Your heart works much harder to force it through. Over time, the heart muscle gets weak. It can become enlarged and stop working properly. When your blood doesn’t flow well, your body doesn’t get enough oxygen.
