Percutaneous coronary intervention is a treatment option for people with coronary artery disease. This nonsurgical procedure helps open narrowed or blocked coronary arteries.
Coronary artery disease (CAD) is when arteries in your heart cannot deliver enough oxygen-rich blood to the tissue of your heart. It often develops from the buildup of plaque inside the arteries, which causes them to narrow over time.
CAD is the most common type of heart disease and is the major cause of heart attacks. According to the
Percutaneous coronary intervention (PCI) is a treatment for CAD. It helps open an artery that’s become narrowed or blocked.
Keep reading to learn more about PCI, what the procedure is like, and its associated risks and benefits.
PCI is a nonsurgical, minimally invasive procedure that’s used to open coronary arteries that have become narrowed or blocked with plaque. This helps improve blood flow to heart tissue.
Having a PCI also typically involves the placement of a small mesh tube called a stent. This is placed after the doctor opens the artery and helps to keep the artery open after treatment.
Is a percutaneous coronary intervention the same as an angioplasty with a stent?
Yes, PCI is the same as coronary angioplasty with a stent. Coronary angioplasty is the procedure to open the coronary artery, after which a stent is placed.
A doctor can use PCI to treat a heart attack. When PCI is used to restore blood flow to the heart during a heart attack, it’s called primary PCI.
PCI may also be performed for symptomatic relief in people with angina that doesn’t respond to treatment with medications. In
A doctor evaluates several factors to determine whether PCI is appropriate. These
- the nature, severity, and location of the blockages
- whether you have symptoms and, if so, how severe they are
- ability to tolerate blood-thinning medications
- whether you have any other underlying health conditions, called comorbidities
- your age
- your risk of having one or more complications of revascularization, often assessed with a risk score
Typically, a cardiologist performs a PCI in a hospital. A cardiologist is a type of doctor who specializes in treating conditions that affect the heart.
Using X-ray imaging, your cardiologist guides a catheter through your blood vessels until it reaches your heart. This catheter is typically inserted into a blood vessel close to your groin or in an artery in your wrist. A special contrast dye helps your cardiologist see where the blockages are.
Next, a catheter with a balloon tip is used to open the artery. Once it’s in position, the balloon is inflated, which pushes the artery open. Then, your cardiologist typically places a stent to help the artery stay open.
A PCI can take between 30 minutes and 2 hours. Many people go home the same day. However, depending on your situation, you may need to stay in the hospital overnight.
What’s recovery like from a percutaneous coronary intervention?
When you leave the hospital, your care team will give you discharge instructions on:
- medications (people who’ve had a PCI with a stent placement need to take at least one antiplatelet drug for the rest of their lives)
- wound care
- diet and lifestyle recommendations
- when to resume activities
You can also ask your doctor whether you’re eligible for a
PCI can also reduce angina symptoms in people with CAD. For example, the
- have had a heart attack but didn’t receive immediate PCI or coronary bypass surgery
- had previously received a PCI for a heart attack but still had coronary artery lesions
- experienced a non-ST-segment-elevation acute coronary syndrome
However, PCI doesn’t seem to lower the risk of heart attack in people with stable CAD. Stable CAD is defined as episodes of chest discomfort due to a coronary blockage that occurs with exertion and is quickly (within minutes) relieved with rest. It does not increase in frequency or severity.
Clinical trials, including
Several complications can happen due to PCI, including:
- excessive bleeding
- damage to blood vessels or to the heart
- kidney damage
- heart attack or stroke due to blood clots generated during PCI
- an allergic reaction to the contrast dye
- re-narrowing of the affected artery
If you’re going to have a PCI, your doctor will explain the various risks associated with the procedure to you beforehand. Make sure to ask any questions or raise any concerns you may have during this time.
PCI is a procedure that’s used to treat CAD. It works by opening coronary arteries that have become narrowed or blocked due to plaque buildup. A stent is also often placed to help hold the artery open.
Having a PCI can be lifesaving if you’re having a heart attack. While PCI can improve angina symptoms and quality of life in people with stable CAD, it hasn’t been shown to reduce the risk of heart attack or death in this group.
Several risks are associated with PCI, including blood clots, infection, and damage to the blood vessels or heart. It’s important to go over these with your doctor before your procedure.
