Coronary angiography is a medical imaging procedure used to examine the coronary arteries, the blood vessels that supply oxygen-rich blood to the heart muscle. This diagnostic test plays a crucial role in identifying blockages or narrowing in these arteries, which can lead to conditions like coronary artery disease and heart attacks.

The procedure typically involves inserting a thin, flexible tube called a catheter into an artery, usually in the groin or arm. This catheter is carefully guided through the blood vessels until it reaches the coronary arteries. Once in place, a special dye, or contrast agent, is injected through the catheter. This dye makes the coronary arteries visible on X-ray images.

As the dye flows through the arteries, an X-ray machine takes a series of images, creating a detailed map of the blood flow. Cardiologists analyze these images to detect any abnormalities, such as plaque buildup (atherosclerosis) or blood clots, which can impede blood flow to the heart. The severity and location of any blockages can be precisely determined.

Coronary angiography is a vital tool for diagnosing and planning treatment for coronary artery disease. The information obtained from the procedure helps physicians decide on the most appropriate course of action, which may include medication, angioplasty with stenting, or coronary artery bypass surgery. While generally safe, the procedure does carry some risks, and it is performed in a specialized cardiac catheterization laboratory by trained medical professionals.
