About Primary Plmonary Hypertension (PPH)

  • Primary pulmonary hypertension (PPH) is a rare disease that affects approximately 2-3 patients per million worldwide each year and is responsible for about 125-150 deaths per year in the United States. In most cases, PPH untreated is rapidly fatal.
  • The average time to diagnosis in patients with PPH is two years. The presumed reason is due to the fact that an extensive workup is necessary to elucidate the cause of a patient's elevated pulmonary artery pressure, and the early symptoms are non-specific. Survival in patients with PPH who are untreated is approximately 30% at 3 years.
  • Common symptoms of PPH are shortness of breath, weakness, and fainting episodes. Women are more likely to be symptomatic than men.


Balancing Virtual and In-Person Care

  • Ronald J. Oudiz, M.D., and Traci Stewart, R.N., discuss the importance of in-person medical care to manage your pulmonary hypertension (PH). They address concerns around COVID-19 exposure and provide safety information and guidelines to help patients feel comfortable and confident when visiting their treatment centers. PHA thanks Janssen Pharmaceuticals, Inc. for its Diamond sponsorship of the PHA Connects fund, which sponsors patient education programming.
