FAQ

Coronary Intervention, also known as Percutaneous Coronary Intervention (PCI), is a procedure used to open narrowed or blocked coronary arteries. These arteries are responsible for supplying blood to the heart muscle. By improving blood flow, PCI helps relieve chest pain, enhance heart function, and lower the chance of a heart attack.

What is a Coronary intervention?

Why is the Procedure Performed?

Coronary intervention is used to restore proper blood flow to the heart and relieve symptoms caused by blocked arteries.

  • Performed to ease chest pain and other effects of coronary artery disease

  • Helps improve heart performance and daily quality of life

  • Often used during heart attacks to quickly reopen blocked arteries and limit damage

  • Recommended when lifestyle changes and medications are not enough

  • Chosen when blockages are too severe for less invasive options

How is the Coronary intervention Performed?

Coronary intervention is typically done with local anesthesia and involves several key steps to restore blood flow to the heart:

  • Artery Access: A small cut is made—usually in the wrist, arm, or groin—so a thin tube (catheter) can be inserted into an artery.

  • Navigation: Using live X-ray imaging, the catheter is gently moved through the blood vessels toward the area of blockage in the heart.

  • Clearing the Blockage: When the catheter reaches the narrowed artery, a small balloon at its tip is inflated to widen the vessel. In many cases, a stent (a tiny mesh tube) is placed to keep the artery open.

  • Finishing Up: The balloon is deflated and the catheter is withdrawn. If a stent was used, it stays in place to support ongoing blood flow.

What are the Risks and Benefits?

Benefits

  • Can provide fast relief from symptoms like chest discomfort or shortness of breath.

  • Helps restore healthy blood flow to the heart muscle.

  • May lower the chance of experiencing a heart attack later on.

  • Allows for improved participation in daily or physical activities.

Risks
As with any medical procedure, Coronary Intervention does involve potential risks. These may include:

  • Bleeding or bruising at the site where the catheter is inserted

  • Allergic response to the contrast dye

  • Injury to blood vessels

  • Heart attack or stroke during the procedure

  • In rare cases, the need for emergency open-heart surgery if complications occur

There’s also a chance the artery could narrow again (restenosis), or that a clot could form inside the stent. Every patient’s health situation is different, so it's important to talk with your doctor about your risks and benefits to determine if this procedure is right for you.

Preparing for Your Coronary intervention Procedure

What to Expect

During the procedure, you’ll remain awake but relaxed thanks to sedative medication. The area where the catheter is placed—usually your wrist or groin—will be numbed with local anesthesia. You may feel mild pressure, but you shouldn’t feel pain. The procedure generally lasts between 30 minutes and a few hours, depending on your specific condition.

How to Prepare for Your Procedure

  • Fasting: Don’t eat or drink anything for 6 to 8 hours before your scheduled procedure.

  • Medications: Talk to your physician about your current prescriptions. Some may need to be paused or adjusted.

  • Pre-Procedure Testing: You may need blood work, a chest X-ray, or an EKG to ensure you're ready for the procedure.

Medications to Discuss Before the Procedure

  • Blood Thinners: Let your doctor know if you take blood thinners. Some may need to be stopped a few days in advance.

  • Diabetes Medication: If you're diabetic, your doctor will give special instructions about insulin or oral medications.

  • Herbal Supplements & NSAIDs: Stop taking these unless otherwise directed, as they can raise your bleeding risk.

What to Bring with You

  • A complete list of all your medications, including supplements and over-the-counter items.

  • Identification and insurance cards.

  • A change of clothes and personal care items, in case an overnight stay is needed.

After the Procedure

  • Recovery: You’ll stay in a monitored recovery area for a few hours. Once you’re fully awake and stable, you can have fluids and a light meal.

  • Activity: Avoid heavy lifting or strenuous activity until cleared by your care team.

  • Wound Care: Follow instructions carefully to keep the insertion site clean and free of infection.

  • Medications: You may be prescribed blood thinners to prevent clotting—take them exactly as instructed.

Tips for a Healthy Recovery

  • Get plenty of rest in the days following your procedure.

  • Stay well hydrated, unless told otherwise by your doctor.

  • Eat a balanced, heart-healthy diet to support healing.

  • Join a cardiac rehab program if your provider recommends it.

When to Call Your Doctor

  • Sudden chest pain, shortness of breath, fainting, or heavy bleeding should be treated as emergencies.

  • Watch for infection signs around the catheter site such as redness, swelling, warmth, or discharge, as well as fever.

  • This procedure is typically recommended to relieve symptoms of coronary artery disease, such as chest pain (angina), to improve your quality of life, or to treat a heart attack. It is considered when medications and lifestyle changes are not enough to manage your symptoms.

  • Prepare by fasting for 8 hours before the procedure, adjusting or stopping certain medications (especially blood thinners and diabetes medications) as advised by your physician, and arranging for transportation since you will not be able to drive yourself home after the procedure.

  • You’ll be awake but sedated, and a small tube (catheter) will be inserted through your wrist or groin to reach your heart, will be numbed with a local anesthetic. The procedure is usually not painful and usually takes about 30 minutes to a few hours.

  • While complications are rare, risks may include bleeding, infection, allergic reaction to contrast dye, and blood vessel damage.

  • You will be monitored in a recovery area for several hours. Once the sedation wears off, and it is deemed safe, you will be allowed to drink and eat.

  • Many patients return to work within a week, but those with physically demanding jobs may need more time. Your healthcare team will provide personalized advice based on your condition and recovery progress.

  • Adopting a heart-healthy lifestyle is crucial. This includes eating a balanced diet, maintaining a healthy weight, quitting smoking, managing stress, controlling blood pressure and cholesterol levels, and staying physically active within the guidelines provided by your healthcare team.

  • Call your doctor if you experience chest pain, trouble breathing, a fever, or unusual bleeding, swelling, or redness at the insertion site.

  • You may be prescribed additional medications following your procedure. Please follow instructions provided by the physician. It is crucial to take these medications exactly as prescribed to prevent complications.

  • Once you’re fully awake and stable, you’ll be allowed to eat and drink—often starting with water and light food.
