The Portuguese Pulmonary Hypertension Association (APHP) is a nonprofit organization working nationwide to improve the quality of life and well-being of people affected by pulmonary hypertension. Its work combines information, practical guidance, community support, and efforts to raise awareness of the disease and the need for a cure.

APHP provides educational resources on pulmonary hypertension and chronic thromboembolic pulmonary hypertension, including information about clinical descriptions, classifications, causes, symptoms, diagnosis, treatment, and disease statistics. Its guidance for living with the condition addresses psychosocial support, pulmonary hypertension in childhood and everyday life, the role of family and friends, travel, and specialist consultations. The association also shares informational leaflets, brochures, books, and bibliographic sources, alongside news about science, research, and events.

Through awareness activities, fundraising appeals, and opportunities to collaborate, APHP invites the public to support people living with pulmonary hypertension. The organization also offers APHP-branded merchandise and maintains a YouTube presence, extending its outreach and helping connect its community with information and support.
