A heart attack occurs when the cholesterol plaque accumulates in the walls of the coronary arteries (blood vessels that deliver blood to the heart). People with the possible symptoms of a heart attack can confirm the diagnosis by coronary angiography. Coronary angiography is a procedure that combines contrast dye and X-rays to identify the blockages in the coronary arteries.
Coronary angiography is an important part of clinical evaluation in patients who have:
It is also used as a pre-operative procedure in individuals with scheduled heart surgery, who have a high risk of coronary artery disease.

Coronary angiography is usually performed on an emergency basis. If the procedure is scheduled in advance, then the person may need to follow these instructions:
Before initiating the procedure, a sedative is given through the IV line to calm the person. Local anaesthesia is administered either on the arm or groin region.
Once the anaesthesia sets in, an incision is made to insert the catheter into the artery. By using the X-rays, the catheter is guided to reach the coronary artery. Once the catheter reaches the artery, a contrast dye is injected to highlight the blockage. This blockage is observed on the X-ray monitor.
Once the catheter is removed, the incision will be closed with a manual clamp. For the first few hours, you will be in a recovery room, where your vitals are checked. You need to lie straight for a few hours to avoid bleeding from the incision site.
