If you have been recommended by your doctor to undergo Coronary angiography, you must practice the following steps before the procedure:

Fasting: 6-8 hours of fasting before the procedure. This is done as coronary angiography uses anesthesia. If you consume any food item before the test, you may suffer from some complications. 

Medical Information: You must inform your doctor about the medications you take.

Allergies: If you are allergic to any specific medicine (or contrast material), you should inform the medical specialists at the cath lab. 

Previous experience: If you have faced some difficulties regarding coronary angiography in the past, you should mention it to your doctor. This is essential to avoid further complications.

Pregnancy: If you are pregnant or planning to get pregnant, notify your healthcare provider. 

Diabetes: If you are diabetic, ask your doctor if you should take your medications before the test.

In the course of this procedure, you will be awake. Anesthesia will be given to relax you. 

Firstly, an intravenous (IV) line will be inserted into the vein of your arm. A thin flexible tube (catheter) will then be inserted from your groin or arm. 

The doctor will make a small cut for the entry of a plastic tube called a sheath. The sheath will be placed in your artery. 

The catheter will then be directed to the respective coronary artery. At this point, a dye will be flushed through the catheter. This dye allows the X-ray machine to capture images for the doctor's reference.

After the procedure is completed, the following steps will be performed by the medical expert or nursing staff:

• The catheter will be removed and the incision will be closed by manual pressure or a clamp.
• You will be put under observation by the medical staff. You may have to stay at the hospital overnight for monitoring purposes, if reqired.
• Your doctor will ask you to lie down for the first few hours. 
• You will be advised to drink plenty of water. This will help you flush the dye from your body. 
• You should ask your queries with the doctor, before performing routine activities like taking medicines, or bathing. 
• You should avoid doing any activity that may exhaust you. 

Angiography is a safe and sound procedure if performed by qualified experts. However, certain risks are associated with this procedure. The following is a set of such complications that may be generated from this test:

• Irregular heartbeats
• Injury to arteries
• Low Blood Pressure
• Allergy due to the dye used in the procedure
• Swelling or pain in the area where the catheter is inserted
• Blood clots
