Recruitment of Relatives

If you have a family history of Pulmonary Arterial Hypertension, you may be eligible for this study.

We would like first degree relatives (mums, dads, siblings and children) of patients with Heritable Pulmonary Arterial Hypertension to participate in this research study.

Heritable Pulmonary Arterial Hypertension means either a genetic change has been identified as the cause for disease or that there is a family history of the disease.

Relatives aged 16 and over will be seen once per year by their local research team. You will be asked to complete some non-invasive tests including, exercise tests, lung function, heart imaging (echo) and to donate some blood (no more than 100mls). Relatives may choose to have a right heart catheter, this is an invasive procedure that is used to diagnose Pulmonary Arterial Hypertension. You should discuss this option with your local Pulmonary Arterial Hypertension team.

Relatives under the age of 16 may participate in the study but must be seen at Great Ormond Street Hospital, London.
