How To Prepare
Before an angiogram, tell your doctor if you:
- Are or might be pregnant.
- Are
breast-feeding. Use formula (throw out your breast milk) for 1 to 2 days after
the angiogram until the dye has passed from your body. This generally takes 24
hours.
- Are allergic to iodine dye used in the
test.
- Have ever had a serious allergic reaction (anaphylaxis) from any substance, such as the venom
from a bee sting or from eating shellfish.
- Have
asthma.
- Are allergic to any
medicines.
- Have any bleeding problems or are taking blood-thinning
medicines.
- Have a history of kidney problems or
diabetes, especially if you take metformin
(Glucophage) to control your diabetes. The dye used during an angiogram can
cause kidney damage in people who have poor kidney function.
Do not eat or drink for 4 to 8 hours before the angiogram. You may
be asked to not take aspirin, aspirin products, or blood thinners for days
before the test and for 1 day after the test. If you take these medicines, talk
with your doctor.
An angiogram can be done as an inpatient or outpatient. If you are
an outpatient, you will stay in a recovery room for several hours before you go
home. You may want to bring something to do or read to pass the time. Arrange
to have someone take you home because you may get a
sedative before the test. If you stay overnight in the
hospital, you will probably go home the next day.
The test may take several hours, so you will empty your bladder
just before it begins.
You may have other blood tests, such as blood clotting
(coagulation) studies, blood urea nitrogen (BUN), and creatinine, before the
angiogram.
You will need to sign a consent form that says you understand the
risks of an angiogram and agree to have the test done. Talk to your health
professional about any concerns you have regarding the need for the test, its
risks, how it will be done, or what the results will mean. To help you
understand the importance of this test, fill out the
