In its early stages, PAH does not always produce symptoms. As the condition gets worse, symptoms can include:
- Shortness of breath — at first during exercise, and eventually while at rest
- Tiredness
- Fainting or near fainting with exertion
- Pain or pressure in the chest with exertion
- Swelling in legs, ankles and/or abdomen
- Blue tint to the skin and/or lips
- Heart palpitations
- Rapid pulse
