In 2012, a program and scientific symposium was held in Madrid, Spain, as the first World PH Day celebration. The day was officially endorsed by 22 patient associations, 10 rare and affiliated disease organizations and eight scientific societies.

May 5 was chosen as World PH Day because it is the anniversary of the first child's death in Spain from pulmonary hypertension as a result of toxic rapeseed oil more than 30 years ago. In 2013, the May 5 date was upheld as World PH Day by popular consensus.
