ACE inhibitor

A medicine often used to treat high blood pressure. It works by blocking a hormone called angiotensin that makes your blood vessels become more narrow. ACE inhibitors help your arteries to stay more open, which lowers your blood pressure.

Adrenaline

This is a hormone that is released in your body when you feel anxious. It causes some blood vessels to become more narrow and raises your blood pressure.

Aldosterone

This is a hormone produced by your adrenal glands (which sit above your kidneys). Aldosterone makes your body hold onto salt and water, raising your blood pressure.

Ambulatory blood pressure monitoring

This is the name for a 24-hour recording of your blood pressure. A cuff is put around your arm and a small monitor is put around your waist that takes regular readings of your blood pressure through the day and night. The results are used to give a complete picture of what your blood pressure is like throughout the day.

Angina

This is a chest pain that may spread to your arms, neck, face, back or stomach. Angina occurs when narrowed arteries restrict the flow of blood to your heart muscles, meaning that they get less blood when they need it - for example when you are being more active.

Angiotensin receptor blocker (ARB)

A medicine often used to treat high blood pressure. It works by blocking a hormone called angiotensin that makes your blood vessels become more narrow. ARBs help your arteries to stay more open, which lowers your blood pressure.

Arteriosclerosis

This is the thickening and roughening of the walls of your arteries, often caused by high blood pressure. This damage causes the arteries to become more narrow and less flexible, which can raise your risk of heart disease or stroke.

Beta-blocker

A medicine sometimes used to treat high blood pressure. It works by blocking the action of noradrenaline, a hormone produced by your body that can cause some blood vessels to become more narrow, raising your blood pressure. Blocking noradrenaline opens up your arteries and helps to lower blood pressure.

Body mass index (BMI)
