An angiogram is a procedure that uses X-ray contrast to look at the blood vessels (arteries or veins) in your body.
When blood vessels are blocked, damaged or abnormal in any way, chest pain, heart attack, stroke, or other problems may occur. Angiography helps your physician determine the source of the problem and the extent of damage to the blood vessel segments that are being examined.
Lab work may be needed before the angiogram to determine your blood's ability to clot.
Please follow these guidelines after midnight the night before your test:
Always consult with your primary physician and/or physician requesting this test before discontinuing any medication. Here are some guidelines:
If you have diabetes
Eating and drinking
Patients must have a responsible, adult driver to accompany them home upon discharge. This will be verified at time of check in. NOTE: Procedure may be rescheduled in the absence of a responsible driver.
Please do not bring valuables such as jewelry or credit cards.
You will meet with your physician, and he or she will review further instructions and discuss any questions you may have. The physician will also review your medical history.
In almost all cases, laboratory tests ("blood work") will be needed, and your physician will need to study the results before beginning your angiogram. It may be several hours before the laboratory results are available.
Every effort will be made to perform your test at the scheduled time, but delays do occur. Please understand that at times our department may experience unplanned urgent or emergent patients that require immediate attention. We are committed to excellent service and are working hard at providing on time care in crisis situations. You may want to bring a book or magazine.
You will be monitored for 4 to 6 hours. At that time, the radiology nurse will discuss at-home instructions with you. You will be provided with a written form of these instructions. Please follow these at home.
A radiologist will evaluate you before you are discharged. Then your physician will discuss the test results with you.
If you have diabetes, do NOT take Glucophage (metformin hydrochloride) for 48 hours after the test to reduce the risk of kidney complications.
We recommend a responsible adult stay with you overnight after your procedure. On occasion, it may be necessary for you to spend the night in the hospital.
Angiography allows your physician to view how blood circulates within vessels at specific locations in the body. This diagnostic test is used to locate the specific source of an abnormality in the neck, kidneys, legs, or other sites.
