A coronary angiogram is a procedure that uses X-ray imaging to see your heart’s blood vessels. The test is generally done to see if there’s a restriction in blood flow going to the heart. Coronary angiograms are part of a general group of procedures known as heart (cardiac) catheterizations. Cardiac catheterization procedures can both diagnose and treat heart and blood vessel conditions. A coronary angiogram, which can help diagnose heart conditions, is the most common type of cardiac catheterization procedure.
During a coronary angiogram, a type of dye that’s visible by an X-ray machine is injected into the blood vessels of your heart. The X-ray machine rapidly takes a series of images (angiograms), offering a look at your blood vessels. If necessary, your doctor can open clogged heart arteries (angioplasty) during your coronary angiogram.
Why it’s done?
Your doctor may recommend that you have a coronary angiogram if you have:
✓ Symptoms of coronary artery disease, such as chest pain (angina)
✓ Pain in your chest, jaw, neck, or arm that can’t be explained by other tests
✓ New or increasing chest pain (unstable angina)
✓ A heart defect you were born with (congenital heart disease)
✓ Abnormal results on a noninvasive heart stress test
✓ Other blood vessel problems or a chest injury
✓ A heart valve problem that requires surgery
