What is the purpose of performing a coronary angiogram?

The purpose of performing a coronary angiogram is to visualize the coronary arteries and identify blockages. This diagnostic procedure involves the use of contrast dye that is injected into the coronary arteries, which allows for X-ray images to be taken. The resulting images reveal any obstructions or narrowing within the arteries that may impede blood flow to the heart muscle, which is crucial for diagnosing conditions such as coronary artery disease. This visualization helps healthcare providers determine the severity and location of blockages, guiding subsequent treatment options, such as angioplasty or stenting, to restore proper blood flow.
