Overall aim of this study

The aim of this study is to set up a UK cohort of patients with idiopathic and heritable pulmonary arterial pulmonary hypertension (PAH) for research into the causes and potential treatments of this condition.  PAH is a life-limiting, rare disease characterised by high blood pressure in the lungs. As a part of this study we wish to recruit controls for comparison studies.

We would also like to collect some of your medical information such as past medical history. All information will be anonymised, each participant only be identified by a unique study number and all personal information (e.g. name) will be removed.
