Before the Procedure

You will be asked whether you have any allergic reactions to medicines or food, especially to X-ray contrast or iodine compounds. You are advised to inform the doctor of your allergies.

You may be asked to abstain from food six hours before your angiography. Generally you should continue all your medicines unless informed otherwise by your doctor. If your procedure is in the afternoon, a full breakfast may be taken.

The day before the procedure, you should try and get a good night’s sleep. If necessary, ask for some sleeping medication.

Day of the Procedure

On the day of procedure, you will be asked to remove your dentures, contact lenses and any jewellery. Please do not bring any money or valuables on the day of your procedure.

After the Procedure

Your doctor will evaluate the results and then advise you on the most appropriate treatment. You may be discharged on the same day after the procedure.

If there is severe narrowing in your artery, the cardiologist may perform coronary angioplasty for you immediately after the angiography. Otherwise, you will be asked to return another day for the procedure or for coronary artery bypass graft surgery.
