Coronary Angiogram Service

A Coronary Angiogram is an invasive test to find out if there are any narrowing or blockages in your coronary arteries. The consultant will inject dye into the coronary arteries and X-ray pictures will be taken of your heart (coronary) arteries. This is how your cardiologist will see if there are any narrowing or blockages. The procedure takes approximately 15 -30 minutes.



If you are having a Coronary Angiogram you may be given the option of having intravenous sedation. The sedation is given through a cannula (small plastic tube) placed in the vein. You will feel sleepy and relaxed following the sedation but you will not be unconscious (this is not a general anaesthetic).

If you have sedation

  • You must have someone to accompany you home and remain with you for 12 hours
  • You must not drive or operate machinery for 24 hours
  • You must not consume alcohol for 24 hours
  • You should not make any vital decisions or sign any legal documents for 24 hours
  • You should not take any medication not prescribed or acknowledged by your doctor



An angiogram is a relatively safe test and serious complications are rare. The risk depends on your overall health and your individual heart condition – your doctor will not recommend the test if they don’t feel the benefits outweigh the small risk.

  • Minor bruising at the puncture site.
