Coronary Angiogram: What It Is, How It’s Done, and What to Expect

What is a Coronary Angiogram?

A coronary angiogram is a special test that shows the blood flow in your heart’s arteries. Doctors use this test to look for blockages or narrow spots. During a coronary angiogram, a thin tube called a catheter goes into a blood vessel. Then, a dye is injected to make the arteries visible on X-ray images. This test helps doctors see if your heart is getting enough blood. According to the American Heart Association, it is a common and safe way to check heart health.

Why is a Coronary Angiogram Needed?

Doctors may suggest a coronary angiogram for several reasons. For example, you may have chest pain or symptoms of heart disease. Sometimes, other heart tests show possible problems. In these cases, a coronary angiogram helps find the cause. It also helps doctors plan the best treatment. In addition, this test can check how well treatments like stents or bypass surgery are working. If you have risk factors for heart disease, your doctor may recommend this test to be sure your arteries are healthy.

How to Prepare for a Coronary Angiogram

Preparation is important for a safe and smooth procedure. Your doctor will give you clear instructions. Usually, you will need to:

Stop eating or drinking for several hours before the test

Tell your doctor about all medicines you take

Discuss any allergies, especially to iodine or contrast dye

Arrange for someone to drive you home after the test

Sometimes, you may need to stop certain medicines before the test. Always follow your doctor’s advice. If you have diabetes, ask about how to manage your blood sugar on the day of the test.

The Procedure: Step-by-Step

Knowing what to expect during a coronary angiogram can help you feel more at ease. Here is how the procedure usually goes:

You will change into a hospital gown and lie on a special table.

A nurse will clean and numb the area where the catheter will go, usually in your wrist or groin.

The doctor will insert the catheter into your blood vessel.

Next, a dye is injected through the catheter to highlight your heart’s arteries.

X-ray images are taken as the dye moves through your arteries.

After the images are complete, the catheter is removed.

Pressure is applied to stop any bleeding, and a bandage is placed on the site.

The whole coronary angiogram procedure usually takes about 30 to 60 minutes. You may feel some pressure, but most people do not feel pain.

Risks and Possible Complications

Like any medical test, a coronary angiogram has some risks. However, serious problems are rare. Possible risks include:

Bleeding or bruising at the catheter site

Allergic reaction to the dye

Irregular heartbeat

Infection (very rare)

Damage to the blood vessel (rare)

Most people have no major problems. Still, it is important to tell your doctor if you feel unwell after the test. The World Health Organization notes that the benefits of a coronary angiogram often outweigh the risks, especially when heart disease is suspected.

Recovery and Aftercare

After the procedure, you will rest in a recovery area for a few hours. During this time, nurses will check your blood pressure and the catheter site. You may need to keep your arm or leg straight for a short time. Most people go home the same day. However, you should avoid heavy lifting or hard exercise for a day or two. Drink plenty of water to help flush the dye from your body. If you notice swelling, pain, or bleeding at the site, call your doctor right away.
