What To Expect Before Coronary Angiography

Before having coronary angiography, talk with your doctor about:

  • How the test is done and how to prepare for it
  • Any medicines you're taking, and whether you should stop taking them before the test
  • Whether you have diseases or conditions that may require taking extra steps during or after the test to avoid complications. Examples of such conditions include diabetes and kidney disease.

Your doctor will tell you exactly which procedures will be done. For example, your doctor may recommend coronary angioplasty if the angiography shows a blocked artery.

You will have a chance to ask questions about the procedures. Also, you'll be asked to provide written informed consent to have the procedures.

It’s not safe to drive after having cardiac catheterization, which is part of coronary angiography. You’ll need to have someone drive you home after the procedure.
