01 — Overview

About Angiography

Coronary angiography is the most definitive test for coronary artery disease. A thin, flexible tube (catheter) is passed through an artery in the wrist or groin up to the heart, and a contrast dye makes the coronary arteries visible on X-ray.

The images show the location and severity of any narrowing, which helps your cardiologist decide whether medicines, angioplasty or surgery is the right next step.

02 — Who may need it

  • 01Chest pain suggestive of angina
  • 02An abnormal TMT or other test pointing to blocked arteries
  • 03After a heart attack
  • 04Before certain heart operations

03 — How it is done

  1. 1

    Local anaesthesia

    The wrist or groin is numbed. You stay awake and may be given a mild sedative.

  2. 2

    Imaging

    The catheter is guided to the heart under X-ray and dye is injected to film the arteries.

  3. 3

    Completion

    The catheter is removed and a pressure bandage applied; your cardiologist then discusses the findings.
