A Coronary Angiogram (CAG) is a procedure used to both diagnose and treat coronary artery disease (CAD).
Understanding Coronary Angiogram (CAG)
A CAG, or Coronary Angiogram, uses X-ray imaging to visualize the coronary arteries. It's a critical tool in identifying blockages or narrowing of these arteries, which can lead to heart problems. According to research, a CAG involves cardiac catheterization, where a thin, 2 mm-diameter catheter is inserted into an artery, typically through the wrist, elbow, or groin. This catheter is then guided up to the coronary arteries. A contrast dye is injected through the catheter, making the arteries visible on X-ray images.
Key Aspects of a CAG
- Diagnostic Tool: CAG is primarily used to diagnose coronary artery disease by identifying blockages or narrowing in the coronary arteries.
- Treatment Option: In some cases, a CAG can be followed by an interventional procedure like angioplasty and stenting to treat the identified blockages during the same procedure.
- Cardiac Catheterization: The procedure involves inserting a thin catheter into an artery (wrist, elbow, or groin) and guiding it to the coronary arteries.
- Contrast Dye: A contrast dye is injected through the catheter to make the arteries visible on X-ray images.
