Count Heart stent It is a common medical procedure that aims to treat coronary artery problems and improve blood flow to the heart muscle, as doctors rely on it inside Al Mousa Health Hospital To save the lives of many patients, especially those who suffer from clogged or narrowed arteries as a result of the accumulation of fatty deposits, and contribute to reducing the incidence of heart attacks and relieving the pain of angina, which helps patients better restore their normal lives. The types of stents vary between metal and medicinal, and their choice varies according to the patient’s health condition and the doctor’s opinion.
What is a heart stent?
A heart stent is a small tube that is placed inside the coronary arteries that feed the heart in order to keep them open and ensure normal blood flow. This stent is used to treat blockages or narrowing of the arteries resulting from the accumulation of fatty deposits, which helps reduce the symptoms of angina and prevent heart attacks.
What materials are heart stents made of?
Heart stents are made of durable and safe materials designed to withstand arterial pressure and maintain continuous blood flow. The basic materials used in stent manufacturing include the following:
- Stainless steel (stainless steel): One of the most popular materials because of its strength, durability, and rust resistance.
- Cobalt-chromium alloy: It is characterized by light weight and durability and is suitable for cardiac stents.
- Platinum and chromium alloys: It is used in some types of stents to increase their clarity during x-ray imaging.
- Biopolymers: It is used in biodegradable stents, which gradually decompose after performing their function.
- Nitinol (an alloy of nickel and titanium): It is characterized by its superior flexibility, which helps adapt to the movement of the arteries.
Why do you need a heart stent?
You need a heart stent when the coronary arteries suffer from blockage or narrowing, which leads to a lack of blood flow to the heart muscle, and causes serious symptoms such as angina or heart attacks. The stent is an effective solution to keep the artery open and restore normal blood flow. The main reasons that require the installation of a heart stent include the following:
- Coronary artery obstruction: As a result of the accumulation of fatty deposits (atherosclerosis), which reduces blood flow to the heart.
- الذبحة الصدرية: Especially if they are recurrent or unstable and do not improve with medication.
- Heart attacks: Where a stent is used urgently to reopen the blocked artery and prevent damage to the heart muscle.
- Prevention of recurrent blockage: After undergoing balloon catheterization to prevent re-narrowing of the artery.
- Improving quality of life: By reducing symptoms such as shortness of breath and chest pain, which allows daily life to be carried out normally.
How to prepare for heart stent surgery
Preparing for a heart stent operation requires several steps in order to ensure the success of the procedure and the safety of the patient. Preparation includes the following:
-
1. Comprehensive medical evaluation: The doctor conducts comprehensive examinations, including ECG, blood tests, CT scan, or diagnostic catheterization, to determine the condition of the arteries, and reviews the medical history and medications that the patient is taking, especially fluid medications.
-
2. Stopping some medications: The doctor may ask to stop certain medications, such as blood thinners, before the operation to reduce the risk of bleeding, and allow other medications, such as heart or high blood pressure medications, to continue according to the doctor’s advice.
-
3. Fasting: You must fast for 6 to 8 hours before the operation to ensure the safety of the procedure, which is usually performed under local anesthesia.
-
4. Preparing the catheter site: The area where the catheter will be inserted, often in the groin or arm, is cleaned and sterilized, and the area may be shaved to reduce the risk of infection
-
5. Psychological preparation: The doctor explains the steps of the operation and the expected procedures to reassure the patient, and the patient is given a mild sedative to relieve tension before the operation begins.

How is a heart stent placed?
The heart stent is placed through a medical procedure called cardiac catheterization, which is a simple, non-surgical procedure. It is performed under local anesthesia and its steps include the following:
- Cleans and sterilizes the catheter insertion site, usually the thigh or wrist.
- A local anesthetic is applied to relieve pain at the entry site.
- Devices are connected to monitor heart rate and blood pressure throughout the procedure.
- The doctor inserts a thin, flexible tube called a catheter through an artery in the groin or arm.
- The catheter is guided into the coronary artery using X-ray imaging (color rays).
- A special dye is injected through the catheter to show blocked or narrowed arteries on the X-ray screen.
- A small balloon is inserted through the catheter into the site of the blockage.
- The balloon is temporarily inflated to expand the artery and remove fatty deposits.
- A small metal stent covered with the balloon is inserted.
- When the balloon is inflated, the stent expands and attaches to the artery wall to keep it open.
- The balloon is withdrawn and the stent remains in place permanently.
- The catheter is gently removed and the insertion site is closed with direct pressure or using special medical instruments.
- The patient is monitored for some time to ensure that his condition stabilizes.
- The patient is asked to rest completely for a few hours.
- Medications such as blood thinners are prescribed to prevent clots around the stent.
- The doctor follows up the patient's condition through periodic checks to ensure that the stent is working well.
What are the complications of installing a heart stent?
Some complications may occur after cardiac stent placement, although the procedure is safe and effective in most cases. These complications include the following:
- Bleeding: It may occur at the site of catheter insertion, especially in the thigh or wrist.
- Artery damage: Due to the insertion of a catheter, which may lead to narrowing or rupture of the artery.
- Allergies: towards the dye used during catheterization.
- Heart attack or Stroke: It is rare but may occur during surgery if a blood clot moves to the heart or brain.
- Re-narrowing of the artery: It may occur in some cases, especially with non-drug metal stents, due to the growth of excess tissue inside the stent.
- Blood clot inside the stent: Which may cause sudden blockage of the artery and lead to a heart attack, and often occurs if the patient does not adhere to fluid medications.
- Arteritis: It is rare, but it may occur as a result of the body's reaction to the material from which the stent is made.
- Irregular heartbeat: It may appear temporarily after the stent is installed.
- Kidney problems: Because of the effect of the dye used during catheterization on the kidneys, especially in patients with chronic kidney disease.
What happens when a heart stent is installed?
When a heart stent is installed, the patient goes through several steps aimed at opening the blocked artery and improving blood flow to the heart muscle. The procedure begins with inserting a thin tube called a catheter through an artery in the thigh or arm, and it is directed using X-rays to the affected coronary artery.
Upon reaching the site of the blockage, a small balloon is inflated to expand the artery, then a metal mesh stent is placed in the newly opened place to keep the artery open. After the operation, the patient is monitored for a short period, and he can usually return to his daily activities within a few days while adhering to the doctor’s instructions and taking prescribed medications to prevent blood clots and ensure the success of the treatment.
Frequently asked questions
What is the difference between a catheter and a stent?
Catheterization is a medical procedure in which a thin tube is inserted through an artery to reach the heart to diagnose or treat a blockage. A stent is a small mesh tube placed inside the artery during catheterization to keep it open after the blockage is removed. The catheter helps in diagnosis and treatment, while the stent prevents re-narrowing of the artery and maintains normal blood flow.
Is the process of installing a heart stent dangerous?
The process of installing a heart stent is a safe and effective procedure to treat clogged arteries, especially when performed by expert medical hands. However, it may carry some risks such as bleeding, clots, or irregular heartbeat, but they are rare when following medical instructions and taking prescribed medications regularly. Therefore, the procedure is a safe solution to improve blood flow and reduce heart attacks.
Does a person return to normal after installing heart stents?
Yes, a person can return to his normal life after the installation of heart stents if he adheres to the doctor’s instructions and takes medications regularly. The patient often feels a great improvement in breathing and performing daily activities, and stents also contribute to preventing the recurrence of blockages, but maintaining a healthy lifestyle and following up on periodic examinations is necessary to ensure the success of treatment in the long term.
