Your coronary arteries supply oxygen-reach blood to your heart muscle. When a waxy substance called plaque builds up inside the coronary arteries and blocks blood flow through them, this is called coronary heart attack (CHD). It can damage your heart muscle and put you at a risk having a heart attack. When plaque builds up in the arteries, the condition is called atherosclerosis. Plaque blocks the coronary arteries reduces the flow of oxygen-reach blood to the heart. This may cause chest pain and discomfort, it is called angina.
Doctors use stents to treat narrowed or blocked coronary arteries. It can also be used to improve the blood flow immediately after heart attack.
What is stent?
A stent is small mesh tube that is used to treat narrow or block arteries. Arteries are blood vessels that supply blood from your heart to other parts of your body.
Cardiac Stent Procedure
First of all, doctors insert a stent under general anesthesia, they make a small incision in your growing, arm or neck then they insert a catheter with a stent and balloon on the tip. Doctors use particular dyes and monitors to guide the catheter through the blood vessels to the narrowed or blocked arteries. When they reach the narrowed or blocked area they inflate the balloon, this expands the stent and stretches the arteries. Finally the doctors deflate the balloon, remove the catheter and leave the stent behind.
Doctors will prescribe some medications to help prevent clotting with the stent. As your arteries starts to heal your own tissue, will start to merge with mesh of the stent. Doctors will also advise to control the risk factors, such as high cholesterol, blood pressure and overweight.
Benefits of cardiac stent
Stent has a good impact on quality of life, it improves your blood flow and prevents further damage to your heart muscle as well as it stops symptoms of heart disease, such as chest pain, shortness of pain, etc. Stenting is much less invasive procedure than bypass surgery; recovery time is also shorter than bypass surgery. It takes a few days to recover from stenting, while bypass surgery may take 1 month or more to recover from it.
