Effects of PAH
PAH is a lifelong condition
PAH is a chronic, progressive disease. Progressive means that the symptoms of PAH will get worse over time. This may require hospitalizations.1
You play an important role in your treatment. Start by keeping track of your symptoms and how they affect you. Then partner with your healthcare team and set treatment goals.
PAH Functional Class*
Functional class is a common way to measure the severity of each patient's PAH. The World Health Organization (WHO) has defined 4 functional classes.2 The higher the class, the more serious PAH is. Make a note of your functional class each time it's measured. You can also talk with your healthcare team about your functional class.
