your family history – although rare, pulmonary arterial hypertension can run in families
any medication you're currently taking
any other medical conditions you have
You may also have a physical examination where your GP will listen to your heart and lungs, and check for any swelling in your legs or ankles.
If your GP thinks you may have pulmonary hypertension, they'll recommend further tests.
The two 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
