PRP's CT Coronary Angiography Service Information

A CT Coronary Angiography is a non-invasive scan where the coronary arteries and chambers of the heart are viewed with the aid of a contrast injection to determine if there has been any plaque build-up. As your heart rate needs to be between 50-60 beats per minute, we may need to utilise beta-blocker medication in order to achieve this.

Please advise us beforehand

If you have had an adverse reaction to a previous contrast injection or other drugs or if you have any renal impairment. We will ask you to complete a questionnaire before the examination and sign a consent to the contrast injection if it is required for your examination.

If you are, or may be, pregnant.

Preparation

No caffeine for 8 hours prior (no tea, coffee or chocolate).

Fast 2 hours prior to appointment and arrive well hydrated (water only).

Bring current list of medication.

Special precautions

You may not be able to have this test performed if you have previously had a reaction to X-ray contrast, or have significant renal failure. You must inform staff if there is any chance of pregnancy, or if you are breastfeeding.

Special instructions for diabetics

If your examination requires fasting, then book an early morning appointment and have your breakfast and diabetic medication after the examination.

If your examination will require an intravenous injection of contrast medium, we need to know your renal function. Please bring along the results of your most recent blood test creatinine level.

What happens during the procedure

When you arrive, we will take your medical history, and all paperwork will be completed. We will then check your heart rate – if your heart rate is above 60 beats per minute you may be given beta blocker medication.

You will be given a gown to wear and a cannula will be inserted into a vein to administer the contrast. You may be asked to hold your breath as the scans are taken.

How long does it take?

1-2 Hours

After your examination

If you have been given beta blockers, your blood pressure and heart rate will be monitored to make sure they are normal before you leave. You may be given post-examination instructions to follow.

Provided your Doctor permits, drink plenty of fluids for the next 24-48 hours.

Your images and report

After your examination, the most pertinent images from your study will be available on the myPRP patient portal. A report, along with the images will be sent directly to your referring doctor. PRP will store digital copies of all studies on our secure database for comparison with any future examinations.

Please bring any previous X-rays with you.

It is important that you return to your doctor with your examination results. Whether they are normal or abnormal, your doctor needs to know promptly so that a management plan can be formulated.

Possible complications

Allergic reactions to contrast material can occur but significant reactions are rare, and generally respond to adrenaline. Our staff members are equipped and trained to treat contrast reactions.
