How the test is performed:
Coronary angiography is usually performed in conjunction with cardiac catheterization. You will be given a mild sedative prior to the test to help you relax. The study is carried out in a laboratory by a trained cardiologist or radiologist and technicians or nurses. An intravenous (IV) line is inserted into one of the blood vessels in your arm or groin after the site has been cleansed and numbed with a local anesthetic. A catheter is then inserted through the IV and into your blood vessel. The catheter is carefully threaded into the heart using an x-ray machine that produces real-time pictures (fluoroscopy). Once the catheter is in place, contrast material is injected and pictures are taken. How to prepare for the test:
Food and fluid are restricted 6 to 8 hours before the test. The procedure takes place in the hospital and you will be asked to wear a hospital gown. Sometimes, admission the night before the test is required. Otherwise, you will be admitted as an outpatient or an inpatient the morning of the procedure. Your health care provider should explain the procedure and its risks. A witnessed, signed consent for the procedure is required. Tell your doctor if you are allergic to seafood, if you have had a bad reaction to contrast material in the past, if you are taking Viagra, or if you might be pregnant.
