Diagnostic angiogram is a procedure that uses X-rays and dye to visualize blood flow through the arteries

What is Diagnostic Angiogram?

A diagnostic angiogram is a diagnostic procedure that helps to visualize blood flow through the coronary arteries to determine if there are any blockages or narrowings that can cause chest pain or other symptoms. 


The indications for a diagnostic angiogram include chest pain, shortness of breath, or other symptoms of coronary artery disease, where there is a suspected blockage in the arteries of your heart. The procedure may also be recommended for patients who have abnormal results on a stress test or other cardiac imaging tests.

The Procedure

The procedure is performed under local anesthesia, and a small incision is made in the groin or arm to access the artery. A thin, flexible tube called a catheter is then inserted into the artery, and a contrast dye is injected through the catheter to help visualize the arteries on X-ray images. The procedure takes around 30 minutes to 1 hour, depending on the complexity of the case. Patients are given a mild sedative to help them relax during the procedure. The images produced during the procedure can provide valuable information about the location and severity of blockages or narrowings in the arteries.
After the procedure, patients are usually monitored for a few hours to make sure there are no complications. Most patients can go home the same day unless a complication arises, in which case they may need to stay overnight. The results of the procedure can help guide treatment decisions, including the need for angioplasty or stenting to restore blood flow in the affected artery.
