Pulmonary hypertension is a serious and potentially fatal lung disease for which there is no cure. It is a condition that affects the arteries of the lungs, hindering the flow of blood and oxygen to the heart. People living with PH suffer from continuous high blood pressure in the lungs, which results in an enlargement of the heart. If left untreated, this will often lead to a weakness of the right-side of the heart, a serious type of heart failure. PH can strike anyone. It typically affects people between 20 and 60 years of age, but PH can also affect children and the elderly.

In Canada, World PH Day is brought directly to communities across the country. Each year members of the PH community encourage their local community leaders to recognize World PH Day by lighting up a local monument purple. Since 2014, thanks to these efforts, monuments have been illuminated in periwinkle purple on May 5th from coast to coast.
