One of the most exciting and significant efforts undertaken by Canada’s pulmonary hypertension community in the last five years is the Canadian Pulmonary Hypertension Registry (CPHR).  



What is the CPHR and why was it started?

 The CPHR is a database of patient data collected to help better understand pulmonary hypertension (PH) and improve patient care. Data on the Canadian PH population is lacking, especially for the rarest forms of PH, PAH and CTEPH. This registry allows us to understand PH better and its impacts on patients.

Your participation is essential to the success of CPHR

Your local PH clinic team will have more information about the registry and how to sign up.
Once you are signed up, you will not have to do anything extra. The registry will collect only the relevant data from your medical chart, allowing researchers to use the data collected for future research and quality improvement projects. We can use the data to advocate for more funding and resources in PH patient care. We can also use data to educate and promote awareness of PH.

Your personal information is safe

 You will never be identified individually. Your data will be grouped with other data and used in reports, publications, and presentations.
