A device which stimulates the heart to beat. It is about the size of a small matchbox and is usually placed under the skin of the chest.


Percutaneous Coronary Intervention (PCI)

Similar to an angiogram, PCI uses x-ray to look at the blood supply to the heart. Dye is injected using a fine catheter (tube) passed through a blood vessel in the groin. X-rays are then taken to identify if there is any narrowing or blockages of the blood vessels around the heart. If blockages are found these will sometimes be treated (using a stent to keep the vessel open) to improve the blood flow.


A small metal mesh coil which is used to hold the artery open following balloon angioplasty. There are currently two types of stents in use: ‘bare metal or ‘uncoated’ stents, and ‘drug-eluting’ or ‘coated’ stents (coated in a drug to reduce the risk of the artery narrowing following angioplasty).

Cardiac Rehabilitation

A programme to help people who have had heart attacks or cardiac surgery. It aims to help the patient make lifestyle changes and exercise to prevent a recurrence or worsening of heart problems.
