Coronary angiography is a diagnostic procedure to observe how blood flows through the heart’s arteries and blood vessel function using x-ray imaging technology. It detects artery narrowing and blockage and is the most commonly performed type of cardiac catheterisation procedure used to diagnose and treat conditions related to the heart and blood vessels.
During a coronary angiography procedure, a contrast dye is injected into the heart’s blood vessels, which will help detect blockages and the locations they are in. Your doctor may perform an coronary angioplasty to insert a stent, or coronary bypass surgery to treat the blockage.
You should fast for at least 8 hours before the procedure and will be required to change into a hospital gown. Blood pressure tests and blood sugar tests are done to ensure you are fit enough to proceed with the procedure.
You will remain awake throughout the painless procedure. Your doctor will clean the insertion area with an antiseptic wipe and you will be given a local anesthesia. A thin tube called a catheter will be inserted into a blood vessel in certain parts of the body, such as the arm, groin, or neck. The catheter is moved slowly to the coronary arteries to examine them.
A contrast dye is injected into the bloodstream, where it will flow through and detect any blockage of arteries. You may feel slight discomfort after the dye is injected. Your doctor will observe how the dye travels through your blood stream through a monitor.
You will rest in a recovery room until you feel well enough to leave. You will be given a follow up appointment to review your test results.Should you feel unwell, contact your doctor immediately or call our 24-HR Emergency Clinic.
