Coronary angiography is a diagnostic procedure that lets doctors directly visualise the coronary arteries, the blood vessels that supply the heart muscle. It is generally advised when there is a clinical reason to look more closely at blood flow to the heart.
Your cardiologist may recommend angiography if there is suspected coronary artery disease, persistent or concerning chest pain, abnormal findings on tests like an ECG, TMT or 2D Echo, or as part of evaluating a heart attack.
The procedure involves passing a thin catheter through an artery, commonly in the wrist (radial approach) or the groin (femoral approach), up to the heart's blood vessels. A contrast dye is then used to make the arteries visible on an X-ray, helping identify any narrowing or blockage.
If angiography does reveal a blockage, your cardiologist will discuss the findings with you and explain the possible next steps, which may or may not include a procedure like angioplasty, depending on your specific situation.
