What Are Heart Stents, and How Do They Work?

Heart stents are small, mesh-like tubes made of metal or polymer that are used to treat blocked or narrowed arteries in the heart. They work by providing support and maintaining the patency of the arteries, allowing for improved blood flow to the heart muscle. When an artery becomes narrowed or blocked due to the buildup of plaque, a stent can be inserted to open up the artery and restore normal blood flow.

The stent acts as a scaffold, keeping the artery open and preventing it from collapsing or becoming blocked again. This procedure, known as coronary angioplasty or percutaneous coronary intervention (PCI), is minimally invasive and is often performed under local anesthesia.

Heart stents can be either bare metal stents (BMS) or drug-eluting stents (DES). BMS are made of metal and do not contain any medication, while DES are coated with medication that helps prevent the artery from re-narrowing. The choice of stent depends on various factors, such as the patient’s medical history, the location and severity of the blockage, and the presence of any other underlying health conditions. The cardiologist will determine the most suitable type of stent for each individual case.

In addition to their mechanical function, heart stents also promote the healing process within the artery. Over time, the body’s natural response to the stent leads to the formation of a thin layer of cells that covers the stent, reducing the risk of re-narrowing and promoting long-term stability.

Common Types of Heart Stents

There are several types of heart stents available in South Africa, each with its own unique characteristics. The two main categories are bare metal stents (BMS) and drug-eluting stents (DES).

Bare metal stents, as the name suggests, are made of metal, usually stainless steel or cobalt-chromium alloy. They provide physical support to the artery, keeping it open and allowing blood to flow freely.

While BMS are effective in preventing immediate re-narrowing of the artery, they have a higher risk of long-term re-narrowing compared to drug-eluting stents.

On the other hand, drug-eluting stents are coated with a medication that helps prevent the re-narrowing of the artery. This medication is slowly released into the surrounding tissue, reducing the risk of restenosis. DES have significantly lower rates of re-narrowing compared to BMS, making them the preferred choice in most cases.

Another type of stent that is sometimes used is the bioresorbable stent. These stents are made of a material that gradually dissolves over time, leaving the artery in its natural state. While bioresorbable stents offer certain advantages, such as the potential for complete restoration of normal artery function, they are not yet widely available in South Africa and are mainly used in select cases.

The choice of stent depends on various factors, including the patient’s medical history, the location and severity of the blockage, and the doctor’s preference. It is important to discuss the options with your cardiologist to determine the most suitable stent for your individual needs.

When are Heart Stents Used?

Heart stents are used to treat coronary artery disease (CAD), a condition characterized by the narrowing or blockage of the arteries that supply blood to the heart muscle.

CAD occurs when fatty deposits, known as plaque, build up on the inner walls of the arteries, restricting blood flow and oxygen delivery to the heart.

Heart stents are typically recommended in cases where the blockage is causing symptoms, such as chest pain (angina) or shortness of breath, or when there is a significant risk of a heart attack.

Stents can also be used as a preventive measure in individuals with a high risk of developing CAD, even if they are not currently experiencing symptoms.

It is important to note that heart stents are not suitable for everyone with CAD. The decision to use a stent is made based on a thorough evaluation of the patient’s medical history, symptoms, and diagnostic tests. Other treatment options, such as medication or bypass surgery, may be considered depending on the individual case.

Benefits and Risks of Heart Stents

Heart stents offer several benefits for patients with coronary artery disease. They can relieve symptoms, improve quality of life, and reduce the risk of heart attack. By opening up the blocked or narrowed arteries, stents restore normal blood flow to the heart muscle, allowing it to receive the oxygen and nutrients it needs to function properly.

In addition to the immediate benefits, heart stents also have long-term advantages. Studies have shown that stenting can reduce the need for repeat procedures, such as angioplasty or bypass surgery, in the future. It can also improve survival rates in certain high-risk patient populations.

However, like any medical procedure, heart stenting carries certain risks. The most common complications include bleeding, infection, and damage to the blood vessels or heart. In rare cases, stents can also cause blood clots to form inside the artery, leading to a heart attack or stroke. It is important to discuss the potential risks and benefits with your cardiologist before undergoing the procedure.

The Process of Getting a Heart Stent in South Africa

Getting a heart stent in South Africa typically involves several steps, starting with a consultation with a cardiologist. During the initial evaluation, the cardiologist will review your medical history, conduct a physical examination, and order diagnostic tests, such as an electrocardiogram (ECG), stress test, or coronary angiography, to assess the extent and severity of the blockage.

Once the need for a stent is confirmed, the procedure can be scheduled. Most heart stent procedures are performed in a cardiac catheterization laboratory, also known as a cath lab. The patient is usually given a sedative to help them relax, and a local anesthetic is used to numb the area where the catheter will be inserted.

The stent is inserted into the blocked or narrowed artery using a thin, flexible tube called a catheter. The catheter is inserted through a small incision in the groin or wrist and guided to the heart under X-ray imaging. Once the stent is in place, it is expanded using a balloon, which pushes the plaque against the artery wall, allowing for improved blood flow. The balloon is then deflated and removed, leaving the stent in place to keep the artery open.

The entire procedure usually takes about an hour, but the preparation and recovery time may vary. Most patients are able to go home on the same day or the following day, depending on their condition and the hospital’s protocol.

Recovery and Aftercare for Heart Stent Patients

After the heart stent procedure, the patient will be monitored closely in the hospital for a few hours to ensure there are no immediate complications. Once stable, most patients are discharged and can return home to continue their recovery.

During the initial days or weeks after the procedure, it is important to follow the doctor’s instructions and take prescribed medications as directed. These may include blood thinners, antiplatelet drugs, and medications to control blood pressure and cholesterol levels. It is crucial to take these medications regularly to prevent blood clots and further plaque buildup.

In terms of physical activity, most patients are advised to gradually resume their normal daily activities. Light exercises, such as walking, are usually recommended to improve cardiovascular health and aid in recovery. However, strenuous activities and heavy lifting should be avoided for a certain period of time, as advised by the doctor.

A healthy lifestyle is essential for long-term heart health. This includes adopting a balanced diet rich in fruits, vegetables, whole grains, and lean proteins, and minimizing the intake of saturated fats, processed foods, and sugary drinks. Quitting smoking and managing stress are also important factors in maintaining a healthy heart.

Regular follow-up visits with the doctor are necessary to monitor the progress and make any necessary adjustments to the treatment plan. These appointments may include physical examinations, blood tests, and imaging tests to assess the condition of the stent and the overall health of the heart.

Lifestyle Changes and Precautions After Getting a Heart Stent

After getting a heart stent, certain lifestyle changes and precautions can help maintain the health of the stent and prevent further complications. Here are some important considerations:

1. Medication compliance: It is vital to continue taking prescribed medications as directed by the doctor.
