Everything You Need To Know About Stents For The Heart
A heart attack always brings a wave of fear. However, with the recent techniques, the fatal threat of a heart attack can be managed more effectively. One of the things used in such situations is called a stent. Although this takes care of the immediate fear factor, the anxiety still remains.
If you get to know a little bit about the functionality, scope and the longevity of a stent, you will be able to appreciate this medical boon more.
Let’s get to know about it!
What Is A Stent When Do You Need It?
Usually, a heart attack occurs when the blood supplying arteries get blocked due to blood clots, cholesterol or even weak tissues and prevents blood from going in your heart. When your heart receives less blood for a considerable amount of time, the portion which is deprived of blood suffers from damage. This is what is commonly known as a heart attack.
Now, when you go to a doctor, they suggest to open up the blockage to prevent further damage. Sometimes, it is done through angioplasty. But at other times, if there is a chance of relapse, your doctor recommends for a stent to keep the passage open forever.
So basically coronary stent is small expandable wire mesh or tube where the doctor places in the narrowed artery or duct to open the blockage and to restore the normal blood flow.
Stents clear the blockages and help to treat narrow or weak arteries. They can also be inserted in other areas of the body such as in the brain to support blood vessels or in the ducts that carry urine and bile etc.
Most stents are manufactured with metal. However, some specialized dissolvable stents coated in medication are also available.
How A Stent Is Inserted?
There were several methods to insert a stent. Usually, a stent is inserted by a minimally invasive procedure. The stent is collapsed and put over a balloon catheter and guided through your blood vessels by the smaller incisions to reach the area that needs a stent. Generally, those incisions are made in the groin or arm.
A tube with a camera head at the end is used by a doctor to guide the stent to the blockage. After reaching the blockage, the balloon is inflated and the stent expands. It locks the place and a scaffold is formed which holds the artery open permanently. This helps to relieve symptoms like chest pain and retrieves the normal blood flow to the heart muscle.
Stents are used depending on the size of the artery and location of the blockage and some other characteristics of the artery blockage. Stents are being used in most angioplasty procedures these days. Different types of stents are used in angioplasty which includes:
- Dual Therapy Stent (DTS)
- Bioresorbable Vascular Scaffold (BVS)
- Bio-engineered Stent
- Drug-Eluting Stent (DES)
- Bare Metal Stent (BMS)
What is the life expectancy after the insertion of a stent?
A stent can prevent future heart attacks and saves the artery from further damage.
It restarts the flow of blood and keeps the arteries and veins open. It reduces the risk of a heart attack due to blockage of that particular artery in which it has been inserted.
We can surely talk about the longevity of the stent itself and how long it can function properly. Well, a stent is permanent but what keeps it functioning, depends on various factors.
Once the stent is incorporated inside your artery, you need to maintain a healthy lifestyle so that plaque does not deposit on the stent to avoid the artery blockage again in future. The severity of what caused the blockage, the age of the patient etc. also play a vital role.
The material which makes the stent could be metal or a fusion also decides the strength of the stent. While some make strong stents which stick tight to the walls of your artery, some might be vulnerable to damage or could slip from its original position.
So if you underwent angioplasty with a stent, you should visit your doctor annually or even more, as suggested by your doctor. Coronary stenting is still done for cases where the threat is less. But advancements in the same technologies are aiming at making stenting a solution to more severe cases which would otherwise require surgery.
