your family history – although rare, pulmonary arterial hypertension can run in families
any medicine you're currently taking
any other medical conditions you have
You may also have a physical examination where a GP will listen to your heart and lungs, and check for any swelling in your legs or ankles.
If a GP thinks you may have pulmonary hypertension, they'll recommend further tests.
The 2 main tests used to help diagnose the condition are:
an echocardiogram – a scan that uses high-frequency sound waves to create an image of the heart; it's used to estimate the pressure in your pulmonary arteries and test how well both sides of your heart are pumping
right heart catheterisation – a thin, flexible tube (catheter) is inserted into a vein in your neck, arm or groin, and passed through to your pulmonary artery to confirm a diagnosis by accurately measuring the blood pressure in the right side of your heart and pulmonary arteries; it's carried out in specialist national pulmonary hypertension centres
