A coronary angiography is a test that employs medical imaging to examine the organs and blood vessels of the patient's body in order to determine if a coronary artery is blocked.
A technology based on X-Rays, such as fluoroscopy, is used to perform the test (Immediately obtains moving pictures using X-Ray).
If you have unstable angina, atypical chest pain, aortic stenosis, or unexplained heart failure, your doctor will be concerned that you are at risk of a heart attack.
A contrast dye will be put into the arteries via a catheter (thin, plastic tube) during the test, and your doctor will monitor how blood flows through your heart on an X-ray screen.
A cardiac angiography, catheter arteriography, or cardiac catheterization are all terms used to describe the procedure.
Your doctor may decide that you may benefit from coronary angioplasty or stenting to help clear clogged arteries based on the results of the test.
The following therapies may be performed during your angiography to avoid the need for further procedure:
Coronary Angioplasty is a non-surgical therapy that restores blood flow to the heart muscles by widening blocked or restricted coronary arteries.
It is used to open blood arteries that provide blood to the heart that have become narrowed or obstructed. Coronary arteries are the name for these blood vessels.
A catheter attached to a guide wire is usually introduced into the occluded artery to aid in its widening. Percutaneous Coronary Intervention (PCI) and Percutaneous Transluminal Coronary Angioplasty are other terms for angioplasty (PTCA).
Stenting: This treatment involves inserting a small tube called a stent into a blocked duct to keep it open. Depending on where it's inserted, this stent restores blood or other fluid flow.
Metal or plastic stents are used in this procedure. Stent grafts are larger stents constructed of a particular fabric that are utilised for larger arteries. Stents can also be coated with drugs to prevent a blocked artery from shutting completely.
If you have any of the following symptoms, your doctor may consider a coronary angiography:
Before beginning the angiography treatment, your doctor will go over your whole medical history, including allergies and medications you're using.
Your doctor may perform a physical examination and take your blood pressure and pulse.
The test may be performed on an emergency basis in rare instances. They are, however, usually scheduled ahead of time, allowing you plenty of time to prepare.
The procedure is carried out in the hospital's catheterization (cath) lab.
Before the procedure, your health care team will give you some instructions and chat to you about any drugs you're taking.
The following are some general guidelines:
Before an angiography, you should not eat or drink anything after midnight.
Bring all of your medications to the hospital with you, and consult with your doctor about whether or not you should take your morning pills.
Ask your doctor if you should take insulin or other oral drugs before the test if you have diabetes.
If you're pregnant or think you might be.
If you're a breastfeeding mother (you are not allowed to feed your baby for a day or two, as the dye might still be in your system).
Coronary angiography might take anything from 30 minutes to 2 hours to complete.
The process takes place in an X-ray room.
You'll be asked to lie down on an X-ray table with several cameras that can move about your chest to take photographs.
You will be given sedatives through an intravenous line (IV) inserted into your arm.
During the procedure, you will be requested to stay awake so that you can do deep breathing, cough, and move your arms.
A catheter is placed into a blood vessel through your arm or groyne.
The catheter will be threaded into your coronary arteries with care.
Your blood will be tested for blood pressure and oximetry.
Anticoagulants will be administered to prevent blood clots from forming on the catheter or in the coronary artery.
When a contrast substance (dye) is introduced into your body through the catheter, you will experience a brief flushing.
The doctor monitors the flow of the dye as it passes through your arteries. X-ray scans will be taken on a regular basis.
A coronary angiography, like most operations involving your heart and blood vessels, comes with potential risks and problems, such as radiation exposure from the X-rays utilised.
However, major difficulties are uncommon.
The following are some of the potential hazards and complications:
More informationA coronary angiography test can show how many of your coronary arteries are obstructed or restricted by fatty plaques, which can help doctors figure out what's wrong with your blood vessels (atherosclerosis).
The cost of a coronary angiography test varies between Rs. 12000 and Rs. 25,000.
