A coronary angiogram is a diagnostic test that allows your cardiologist to examine your heart’s arteries for blockages that may hinder the blood flow to your heart muscles. The test uses X-rays to generate images that show the flow of blood in the coronary arteries and detect any abnormalities that may exist.

What is a Coronary Angiogram?

A coronary angiogram is a test that uses contrast dye and X-rays to produce detailed images of the blood flow in the coronary arteries. The test is performed by a cardiologist to evaluate the extent of plaque buildup in your coronary arteries. It helps the doctor to determine if you have blockages and if further treatments like medication, angioplasty or stent placement, or surgery are needed.

When is a Coronary Angiogram Performed?

If you are experiencing symptoms such as chest pain, shortness of breath, or dizziness, which could indicate heart problems, coronary angiogram may be performed. The test may also be done if you have an abnormal stress test or electrocardiogram (EKG) result. Additionally, if you are about to undergo heart surgery, or if you have a history of heart disease, stroke, or diabetes.

How to Prepare for a Coronary Angiogram?

Before your coronary angiogram, you may be asked to fast for several hours before the procedure, avoid certain medications, and arrange for transportation to and from the hospital. You should inform your doctor of any allergies you may have, especially to iodine or shellfish, as these can affect the contrast dye used in the procedure.

What to Expect During the Coronary Angiogram Procedure?

The cardiologist will insert a catheter, a thin, flexible tube, into an artery in your groin or arm. You will receive local anesthesia to numb the area and medication to help you relax. Your cardiologist will then guide the catheter through your blood vessels to reach your heart’s arteries.

Once the catheter is in place, a contrast dye is injected through it, and X-ray images are taken of the coronary arteries. This process may cause you to feel a warm sensation or have a metallic taste in your mouth. You will be asked to hold your breath several times during the test to minimize movement and ensure clear images.

What to Expect After the Coronary Angiogram Procedure?

After the procedure, the catheter will be removed, and the insertion site will be covered with a bandage. You will be asked to rest for several hours before you can go home. You may experience some soreness or bruising at the site where the catheter was inserted, but this should go away after a few days.

The results of the test and findings will be discussed. Depending on the results, you may need further testing, medication, or intervention like angioplasty or stenting to treat any blockages that may have been detected.

Risks of Coronary Angiogram

Like any medical procedure, a coronary angiogram may carry some risks. These include bleeding or infection at the catheter insertion site, an allergic reaction to the contrast dye, blood clots, stroke, and damage to the artery where the catheter is inserted. However, these risks are rare and usually outweighed by the benefits.
