About Coronary Angiography
Coronary angiography uses contrast dye and X-ray imaging to show the arteries supplying the heart. It is performed in our Philips Azurion C5 cath lab and is the test cardiologists rely on to decide whether narrowed arteries need stenting, surgery or medication alone.
Before you read on
Everything here is general information about coronary angiography. Whether it suits you, and how it would be done in your case, is a decision for your doctor after examining you.
Your consultant's instructions always take precedence over anything written on this page.
When is it recommended?
Situations in which a doctor may suggest coronary angiography.
- Chest pain suggesting reduced blood flow to the heart
- Abnormal ECG, TMT or echocardiogram findings
- Assessment after a heart attack
- Planning before cardiac surgery
Procedure details
The usual sequence, from first consultation through to follow-up.
Preparation
Blood tests are checked and you are asked to fast for a few hours before the procedure.
Access
A thin catheter is introduced through the wrist or groin under local anaesthetic.
Imaging
Contrast dye is injected and X-ray images show the arteries as the dye passes through.
Observation
You are observed for a few hours afterwards, and the cardiologist explains the findings.
How to prepare
What to sort out before you come in.
- Blood tests, ECG and a kidney function check beforehand
- You may be asked to pause certain diabetes or blood-thinning medication
- Do not eat for a few hours before, as advised
- Tell us about any allergy to contrast dye or iodine
Recovery
What to expect afterwards, and roughly when.
- You are observed for several hours afterwards, and often go home the same day
- The access site in the wrist or groin is checked before discharge
- Avoid heavy lifting and driving for a day or two
- Drink plenty of fluids to help clear the contrast dye
