The major indications of coronary angiography include:
- Angina or chest pain that is persistent or unstable
- Unexplained discomfort and pain in the upper limbs, jaw, neck, and chest
- Congenital heart diseases or defects
- Severe chest injury or trauma sustained in an accident
You may also be asked to go for coronary angiography if your heart stress test shows any abnormality.
Preparing for the test
Though coronary angiography is usually rescheduled, it may also be carried out on an emergency basis in certain cases. There are a few things that are to be done prior to the procedure:
- The patient should refrain from consuming any solid or liquid food, starting at least 12 hours prior to the procedure.
- The patient needs to inform the doctor about all the medication that you are taking presently.
- The patient needs to empty his/her bladder before the test is initiated. This helps to generate clear images
- The patient needs to remove all the metallic items like pins, jewellery, etc.
What happens during the procedure?
The procedure is carried out while the patient is under the influence of sedatives. You will be asked to lie down on a table and the doctors will fasten safety straps around your limbs and chest to make sure that you do not fall. The table will be tilted at different angles to get a better view and access.
Doctors will place special electrodes on your chest so as to monitor the working of your heart. Your vitals will be checked simultaneously. Once you are in a completely sedated state, the doctors will introduce a catheter in your body via the groin or by making a small incision on your chest, so as to inject the contrast material which helps to generate clearer images. This is followed by taking the X-ray.
What to expect after the procedure?
The coronary angiography procedure lasts for about an hour or more. Following the procedure, you will be asked to lie still for a few hours so as to avoid bleeding at the site of insertion. In the majority of cases, the patients are discharged on the same day while others might be asked to stay overnight.
The patient should refrain from all kinds of vigorous activities and take a lot of fluids to get rid of the residual dye. Rigorous physical activities should also be avoided for a few days.
