When you have pulmonary arterial hypertension (PAH), the blood vessels in your lungs become narrowed and blocked, making it harder for blood to flow through them. This puts extra strain on your heart, particularly the right ventricle, which has to work much harder to pump blood through these constricted vessels.

When you have pulmonary arterial hypertension (PAH), the blood vessels in your lungs become narrowed and blocked, making it harder for blood to flow through them. This puts extra strain on your heart, particularly the right ventricle, which has to work much harder to pump blood through these constricted vessels.

The reduced blood flow and oxygen circulation that occurs with PAH can potentially lead to decreased oxygen levels in your blood, which could increase risk of complications affecting your brain. If you experience any concerning symptoms like dizziness, fainting spells (syncope), irregular heartbeat (arrhythmia), or chest pain, contact your healthcare provider immediately. These symptoms could indicate your PAH needs attention to help prevent serious complications.
