An angiogram is a type of x-ray. It uses a special camera to look at the arteries that feed your heart with blood. An angiogram is a good way to find clogged or narrowed places in these arteries.
Arteries can become blocked over time by a build up of fats and cholesterol called plaque. Narrowed arteries allow less blood and oxygen to reach the heart than is needed. When blood can't flow through your arteries, you may have chest pain known as angina. If the blood flow to the heart is totally blocked, a heart attack occurs.
What will happen in the test?
- You will be asked to go to the heart catheterization laboratory, or "cath-lab".
- You will lie on a hard table near a camera and other equipment.
- The doctor will numb an area on your arm or groin, then insert a thin plastic tube called a catheter into an artery.
- You are awake for the procedure, but may be given medication to relax you.
- A special fluid will be injected to make the arteries of your heart show up clearly on the x-ray.
- Several x-rays will be taken as the fluid goes in. You may be asked to hold your breath or cough.
- You will be able to see the catheter, the movement of your heart and the outline of your arteries on the monitor, if you wish.
How will it feel?
Many patients do not feel pain during the test. Other may feel:
- Pressure at the site where the doctor moves the catheter.
- Chest pain or pressure.
- Shortness of breath.
- A tingling, warm feeling when the fluid is injected.
- The urge to pass urine as the fluid moves through the kidneys.
These are normal, but be sure to tell the doctor if you feel any severe discomfort during the test.
How long does the test last?
That depends on the number of x-ray photos taken and what the doctor needs to look for on the angiogram.
What about after the test?
The nurses or doctor will give you special instructions to follow. The instructions will depend upon which site (groin or wrist) was used. If you have chest pain or discomfort, or a tingly feeling at the catheter site, be sure to let the doctor know.
Your doctor will tell you the results of the angiogram and talk with you about possible treatment.
Where can I get more information?
Talk to your doctor, nurse, or health care professional. If you have heart disease, members of your family may be at higher risk. It's very important for them to makes changes to lower their risk.
