Coronary angiography


Definition:

Coronary angiography is a procedure that uses a special dye (contrast material) and x-rays to see how blood flows through the arteries in your heart.

Alternative Names:

Cardiac angiography; Angiography - heart; Angiogram - coronary

How to Prepare for the Test:

You should not eat or drink anything for 8 hours before the test starts. You may need to stay in the hospital the night before the test. Otherwise, you will check in to the hospital the morning of the test.

You will wear a hospital gown. You must sign a consent form before the test. Your health care provider will explain the procedure and its risks.

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.

How the Test will Feel:

In most cases, you will be awake during the test. You may feel some pressure at the site where the catheter is placed.

You may feel a flushing or warm sensation after the dye is injected.

If the catheter is placed in your groin, you will usually be asked to lie flat on your back for a few hours after the test to avoid bleeding. This may cause some mild back discomfort.

Normal Results:

There is a normal supply of blood to the heart and no blockages.

What Abnormal Results Mean:

An abnormal result may mean you have a blocked artery. The test can show how many coronary arteries are blocked, where they are blocked, and the severity of the blockages.

Risks:

Cardiac catheterization carries a slightly increased risk when compared to other heart tests. The test is very safe when performed by an experienced team.

The risk of complications is very small. Risks of the procedure include the following:

  • Pressure on the heart from the buildup of fluid (cardiac tamponade)
  • Irregular heart beats
  • Injury to a heart artery
  • Low blood pressure
  • Allergic reaction to contrast dye
  • Stroke
  • Heart attack

Small risks from catheterization include:

  • Bleeding, infection, and pain at the IV site
  • Damage to the blood vessels from the catheter
  • Formation of blood clots catheters that could later block blood vessels elsewhere in the body
  • Kidney damage from the contrast (more of a risk in people with diabetes)
Considerations:

If a blockage is found, your health care provider may perform a percutaneous coronary intervention (PCI) to open the blockage. This may be done during the same procedure or at later time, depending on your medical needs.

You may need coronary artery bypass surgery if you have many blockages or blockages in certain arteries. Your doctor may also suggest this surgery if you also have other heart or medical problems.
