Diagnosis and Referral

PH shares a number of its symptoms with other conditions, resulting in many people being misdiagnosed. Without treatment, the average life expectancy of someone with PH is less than three years. Alarmingly, many patients spend two to three years seeking an accurate diagnosis. 

  • PH symptoms are similar to those of other common conditions (asthma, COPD, anxiety, chronic fatigue, etc.).
  • Currently in Canada, it takes more than 2 years for many patients to get diagnosed with PH.
  • 75% of patients have advanced PH when they are diagnosed.
  • Because PH is progressive, early diagnosis is critical to optimal treatment


  • Blood tests
  • Chest X-rays
  • ECG
  • Pulmonary function tests

Referral to specialized centres for confirmation tests
