What is Coronary Angioplasty and Stents?

Coronary artery disease (CAD) is a significant health problem in India, often leading to heart attacks and other serious complications. CAD occurs when plaque builds up inside the coronary arteries, the blood vessels that supply oxygen-rich blood to your heart. This buildup narrows the arteries, reducing blood flow and potentially causing chest pain (angina), shortness of breath, or even a heart attack.

Coronary angioplasty is a minimally invasive procedure used to treat CAD by opening blocked or narrowed coronary arteries. During angioplasty, a tiny balloon is inflated inside the artery to compress the plaque and widen the vessel. Often, a stent (a small mesh tube) is then placed in the artery to help keep it open and prevent it from narrowing again. This combination of angioplasty and stenting can significantly improve blood flow to the heart, relieve symptoms, and lower the risk of future heart attacks. It's a common and effective treatment option for many Indians living with CAD.

Key Facts:

• CAD is a leading cause of death in India.
• Angioplasty and stenting are minimally invasive treatments for CAD.
• The procedure aims to restore blood flow to the heart and alleviate symptoms.
• A stent is often placed to keep the artery open long-term.

Why is Coronary Angioplasty and Stents Performed?

Coronary angioplasty and stenting are performed to address narrowed or blocked coronary arteries caused by CAD. Doctors recommend this procedure in several situations:

Main Conditions/Indications:

• Angina (Chest Pain): To relieve chest pain caused by reduced blood flow to the heart.
• Shortness of Breath: To improve breathing difficulties associated with CAD.
• Heart Attack: As an emergency treatment to quickly restore blood flow during a heart attack.
• Preventing Heart Attacks: To reduce the risk of future heart attacks in individuals with significant blockages.
• Ischemic Heart Failure: Angioplasty can help improve the heart’s pumping function in select cases of heart failure caused by coronary artery disease.

When Doctors Recommend It:

Your doctor may recommend angioplasty and stenting if:

• You have significant blockages in your coronary arteries detected by an angiogram.
• You are experiencing persistent angina despite medication.
• You have had a heart attack and need immediate restoration of blood flow.
• Your overall health makes you a suitable candidate for the procedure.
• A non-invasive test suggests there are significant blockages limiting blood flow to the heart.

Preparation for Coronary Angioplasty and Stents

Proper preparation is crucial for a smooth and successful angioplasty procedure. Here's what you need to know:

Essential Preparation Steps:

• Medical Evaluation: Your doctor will conduct a thorough medical history review, physical examination, and diagnostic tests like blood tests, ECG (electrocardiogram), echocardiogram, and coronary angiogram.
• Medication Review: Inform your doctor about all medications you are currently taking, including over-the-counter drugs and herbal supplements. They may advise you to stop certain medications, especially blood thinners like warfarin or clopidogrel, several days before the procedure. Never stop taking any medication without consulting your doctor first.
• Fasting: You will likely be asked to fast for 6-8 hours before the procedure. This means no food or drinks after midnight the night before.
• Consent Form: You will need to sign a consent form, giving your permission for the procedure. Make sure you understand the risks and benefits before signing.
• Pre-Surgery Check-up: This typically involves blood tests, ECG, echocardiogram, and urine tests to ensure you are fit for the angioplasty.
• Allergies: Inform your doctor of any allergies, especially to iodine or contrast dyes.

India-Specific Tips:

• Arrange for Support: Have a family member or friend accompany you to the hospital and stay with you after the procedure.
• Plan for Travel: If you are traveling from another city or town, arrange for transportation and accommodation near the hospital.
• Gather Medical Records: Bring all relevant medical records, including previous angiograms, ECGs, and blood test results, to the hospital.
• Discuss Costs and Payment Options: Talk to the hospital about the estimated cost of the procedure and available payment options, including insurance coverage and payment plans.
• PCPNDT Act (If Applicable): If you are a pregnant woman (or suspect you might be), inform your doctor immediately as X-ray exposure during the procedure could pose risks to the fetus. Hospitals in India are required to comply with the Pre-Conception and Pre-Natal Diagnostic Techniques (PCPNDT) Act, so be prepared for related inquiries.

What to Expect:

• Arrival at the Hospital: You will be admitted to the hospital on the day of the procedure.
• Pre-Procedure Preparation: A nurse will check your vital signs, insert an intravenous (IV) line, and prepare the insertion site (wrist or groin) by shaving and cleaning it.
• Meeting with the Doctor: You will have a final consultation with your cardiologist to review the procedure and answer any remaining questions.

The Coronary Angioplasty and Stents Procedure

Coronary angioplasty is performed in a specialized cardiac catheterization lab. Here's a step-by-step overview of the procedure:

Step-by-Step:

1. Anesthesia: You will be given a local anesthetic to numb the insertion site (wrist or groin). You may also receive a sedative to help you relax. You will be awake during the procedure.
2. Catheter Insertion: A small incision is made, and a thin, flexible tube called a catheter is inserted into a blood vessel in your wrist or groin.
3. Guidance to the Blockage: The catheter is carefully guided through your blood vessels to the blocked coronary artery, using X-ray imaging (fluoroscopy) to visualize the path.
4. Contrast Dye Injection: A contrast dye is injected through the catheter to make the coronary arteries visible on the X-ray. This helps the doctor locate the blockage.
5. Balloon Inflation: A small balloon at the tip of the catheter is inflated at the site of the blockage. This compresses the plaque against the artery wall, widening the artery and improving blood flow.
6. Stent Placement: A stent (a small mesh tube) is usually placed in the artery to help keep it open after the balloon is deflated and removed. The stent expands to fit the artery wall and remains permanently in place, providing support.
   • Types of Stents:
     • Bare-Metal Stents (BMS): Made of stainless steel or cobalt chrome.
     • Drug-Eluting Stents (DES): Coated with medication to prevent scar tissue formation (restenosis).
     • Bio-Absorbable Stents: Made of materials that dissolve over time (typically around two years).
7. Catheter Removal and Closure: Once the stent is in place, the balloon is deflated, and the catheter is removed. Pressure is applied to the insertion site to stop bleeding. A closure device may be used to seal the artery.

Duration and Comfort Level:

The procedure typically takes between 30 minutes to 2 hours, depending on the complexity of the case. You may feel some pressure or discomfort in your chest during the balloon inflation, but it is usually not painful.

What Happens During the Test:

• You will lie on a table in the cardiac catheterization lab.
• You will be connected to monitors that track your heart rate, blood pressure, and oxygen levels.
• The medical team will be present to monitor you throughout the procedure.
• You will be able to communicate with the doctor and nurses if you have any questions or concerns.

Understanding Results

After the angioplasty, your cardiologist will review the results with you.

What Results Mean:

• Successful Angioplasty: The artery has been successfully opened, and blood flow to the heart has been restored. You should experience relief from angina and other symptoms.
• Residual Blockage: There may be some residual blockage remaining in the artery, but it is not significant enough to cause symptoms.
• Complications: In rare cases, complications such as bleeding, blood clots, or damage to the artery may occur. These will be addressed immediately.

Next Steps:

• Hospital Stay: You will typically stay in the hospital for 1-2 days after the procedure for observation.
• Medications: You will be prescribed blood-thinning medications, such as aspirin and clopidogrel, to prevent blood clots from forming in the stent. It is extremely important to follow your doctor's instructions regarding these medications.
• Lifestyle Changes: You will need to make lifestyle changes, such as quitting smoking, eating a healthy diet, and exercising regularly, to improve your long-term heart health.
• Follow-Up Appointments: You will need to schedule regular follow-up appointments with your cardiologist to monitor your progress and ensure that the stent is functioning properly.
• Cardiac Rehabilitation: Your doctor may recommend a cardiac rehabilitation program to help you recover and improve your cardiovascular health.
