What is it
Coronary angiography is a test that shows the inside of the arteries supplying the heart. A thin catheter is passed to the heart and a contrast dye is injected, so the arteries show up clearly on X-ray images.
Why it is done
It shows exactly where the coronary arteries are narrowed or blocked, and how severely. That picture is what the heart team uses to decide between medicines, angioplasty with a stent, or bypass surgery.
Who needs it
Chest pain or tightness on exertion
An abnormal stress test or ECG
After a heart attack, to find the blockage
Before heart valve or other cardiac surgery
Unexplained breathlessness where coronary disease is suspected
Types and options
Diagnostic coronary angiography - imaging only, to see the arteries.
CT coronary angiography - a scan without a catheter, used in selected patients.
Where a blockage is found and suitable, angioplasty and stenting can sometimes be carried out in the same sitting.
Tests before treatment
ECG
Echocardiography
Stress test or CT coronary angiogram, where done first
Blood tests including kidney function, because contrast dye is used
Review of medicines, especially blood thinners and diabetes medicines
How it is done
The test is done in a catheterisation laboratory under local anaesthetic, and usually takes about twenty to forty minutes.
Recovery
Most patients rest for a few hours afterwards so the puncture site can be watched, and many go home the same day. Heavy lifting and strenuous activity are avoided for a few days. Bruising at the wrist or groin is common and settles.
Benefits and outcomes
Shows the arteries directly, rather than inferring the problem from a stress test
Identifies exactly which artery is narrowed and by how much
Allows treatment to be planned properly, or carried out in the same sitting
Minimally invasive, usually under local anaesthetic
Usually a same-day discharge
Risks and complications
Bruising or bleeding at the puncture site
Reaction to the contrast dye
Effect on kidney function, usually temporary
Blood vessel injury
Rarely, heart rhythm disturbance, heart attack or stroke
Preparing to travel
Fasting for a few hours beforehand, as advised
Bring a list of your medicines and tell the team about any allergy to contrast dye
Blood tests including kidney function
Arrange for someone to accompany you home
Follow instructions on blood thinners and diabetes medicines
