What is a coronary angiogram?
A coronary angiogram is a procedure which looks closely at your coronary arteries to see if they are narrowed or blocked. It uses a special type of X-ray dye.
Why do I need a coronary angiogram?
Your doctor may recommend a coronary angiogram if you are suspected to have coronary artery disease. Coronary artery disease occurs when the arteries that supply blood to your heart are built up with a fatty substance called plaque. This build up causes your arteries to become narrow and hard, meaning less blood is able to reach your heart. A coronary angiogram can also be used to look for other heart problems, such as heart valve disease.

You will be connected to a heart monitor for the duration of your coronary angiogram. The procedure takes less than hour.
What happens after a coronary angiogram?
Once your coronary angiogram is finished, your nurse will apply pressure to the area, followed by a dressing. You will be moved to the recovery area or to the ward to rest. You may be tender or sore and have some bruising at the site of the procedure – this should go away after two weeks. Based on what the coronary angiogram reveals, your doctor will decide if you need to stay overnight in the hospital and the best treatment for you.
You will need to organise for someone to pick you up you from the hospital afterwards and take you home. Once you return home, it is important to follow your doctor’s recommended lifestyle changes, and to visit your doctor or call an ambulance if you experience any serious symptoms.
