How common is PH in Canada?

PH is definitely more common than previously believed. However, it is not clear exactly how many Canadians might suffer from PH. This is because of several reasons:

  • The incidence of PH hasn’t been specifically studied in Canada in Canada
  • There are many kinds of PH
  • Many patients with early or mild PH may not have symptoms, and as a result, have not yet been diagnosed

PH experts have estimated the number of Canadians who might have PH based on studies from the US and Europe:

  • The number of Canadians who may suffer from PAH (one of the most severe types of PH) presently is probably between 2,000 and 10,000
  • Another 250-500 Canadians will develop PAH every year
  • There is clearly a much larger number of Canadians who suffer from other types of PH, and who develop PH every year
