A angiography is a test to find out if you have a blockage in a artery. Your doctor will be concerned that you’re at risk of a heart attack if you have unstable angina, atypical chest pain, aortic stenosis, or unexplained heart failure.
During the coronary angiography, a contrast dye will be injected into your arteries through a catheter (thin, plastic tube), while your doctor watches how blood flows through your heart on an X-ray screen.
This test is also known as a cardiac angiogram, catheter arteriography, or cardiac catheterization.
If you are to have a contrast injection, you should not have anything to eat or drink for four hours before your CT scan.
If you are allergic to iodine or have asthma, please inform the technologist 5-7 days prior to your exam.
If you are taking Glucophage, Glucovance, or Metformin, you will be asked to refrain from taking this medication the day of the exam and for 48 hours after the scan is completed.
Please check with your physician. All other medications should be taken with water if possible.
