What is a Heart Cath or Angiogram?

A heart cath, short for coronary angiography or coronary angiogram, is a diagnostic test that uses X-rays to visualize the blood vessels of the heart. The test is typically used to diagnose or evaluate coronary artery disease (CAD), a type of heart disease that occurs when the coronary arteries, which supply blood to the heart muscle, become narrowed or blocked due to a build-up of plaque.

During a heart cath, a healthcare provider will insert a thin, flexible tube called a catheter into a blood vessel, usually in the groin, arm, or neck. The catheter is then guided through the blood vessel to the heart.

Once the catheter is in place, a dye is injected through the catheter and into the coronary arteries. The dye makes the arteries visible on X-ray images, allowing the healthcare provider to see any blockages or abnormalities in the arteries.

A heart cath is typically performed in a hospital or diagnostic center and typically takes about an hour. The procedure is usually performed while you are awake, but you may be given a mild sedative to help you relax.

It is important to follow any instructions provided by your healthcare provider and to inform them of any allergies or medications you are taking. It is also important to inform them of any symptoms you experience during the procedure.
