Understanding the Angiogram Procedure

An angiogram is a specialized imaging test used to examine blood vessels and identify any blockages or abnormalities. This procedure helps doctors diagnose conditions affecting the heart, brain, or other parts of the body.

Why is an Angiogram Done?

Your doctor may recommend an angiogram if you have:

• Symptoms of heart disease, such as chest pain (angina) or shortness of breath
• Suspected blockages in blood vessels due to conditions like coronary artery disease (CAD), stroke, or peripheral artery disease (PAD)
• Abnormal results from other heart or vascular tests
• The need for a detailed assessment before a procedure like angioplasty or stent placement

How the Procedure Works

Preparation:

• You may need to fast (avoid eating or drinking) for a few hours before the procedure.
• Inform your doctor about any medications, allergies (especially to iodine or contrast dye), or existing medical conditions.

During the Procedure:

• A local anesthetic is used to numb the area, usually in the groin or wrist.
• A thin, flexible tube (catheter) is inserted into an artery and guided to the area being examined.
• A contrast dye is injected through the catheter, making the blood vessels visible on X-ray imaging.
• Your doctor carefully examines the images to detect any blockages or abnormalities.

Duration:

• The procedure typically takes 30 minutes to an hour, but you may need to stay for a few hours for monitoring.

What to Expect After the Procedure

• You may feel slight pressure or discomfort at the catheter insertion site.
• Rest and avoid heavy lifting or strenuous activities for a day or two.
• Drink plenty of water to help flush out the contrast dye.
• Follow your doctor’s instructions regarding medications and follow-up appointments.

Are There Any Risks?

Angiograms are generally safe, but like any medical procedure, there are some potential risks, including:

• Minor bruising or bleeding at the insertion site
• Allergic reaction to the contrast dye
• Rare complications such as infection, blood vessel damage, or clot formation
