In most PH patients, PH gets worse if left untreated. In some PH patients, PH may remain stable over many months or years.
Whether PH gets worse in an individual patient depends on many factors. These include:
  • the cause of PH
  • the severity of PH
  • the age of a patient
  • the general health of a patient
  • the presence of other conditions of the heart, lungs, or body
  • what PH treatment is available to a patient
  • how a patient responds to PH treatment
