Coronary Angiogram (Heart Catherization)

Why Do I Need This Test?
The coronary arteries supply your heart muscle with blood.  They can become clogged from a buildup of cholesterol, cells or other substances.  This can reduce the flow of blood to your heart.  If a blood clot forms and completely blocks blood flow through that artery, a heart attack may occur.
A coronary angiogram is a special x-ray test.  It’s done to find out if your coronary arteries are clogged, where and by how much.  An angiogram can help your doctor see if you need treatment such as angioplasty, stent, coronary artery bypass surgery or medications. 

Angioplasty isn’t necessary for all blockages.  Sometimes all you need to do is take medications and lower your risk for a heart attack by not smoking, decreasing your blood pressure, staying active and eating healthy.

What Happens During an Angiogram?

  1. You may be given medicine to relax you, but you will stay awake.
  2. Your doctor numbs a spot on your groin or arm and inserts a thin tube (catheter) into an artery and up to the heart. 
  3. A dye is injected into the catheter so arteries show up well on the xray.
  4. You may be asked to hold your breath or cough.
  5. By using the xrays the doctor can see if there are any blockages in the coronary arteries.
