What it is
A heart stent is a tiny mesh tube that is placed inside a coronary artery, one of the vessels that supplies blood to the heart. Coronary artery disease can cause these arteries to narrow, and a stent is one tool used to help hold a narrowed section open.
The procedure is often called percutaneous coronary intervention, or PCI. A cardiologist guides a thin tube called a catheter through a blood vessel, often in the wrist or groin, to the heart. A small balloon may be used to widen the artery before the stent is placed.
Stents come in different designs, and some are coated with medicine while others are not. Stents and the devices used to place them are regulated by the FDA. Whether a stent is appropriate for any person is a decision for a licensed clinician after an evaluation.
Some people also wonder whether a stent is related to genetic heart testing. Genetic tests may show inherited risk for some cholesterol or heart conditions, but they do not diagnose heart disease on their own and are not a substitute for a cardiac evaluation.
How it’s traditionally been approached
Stents have traditionally been considered in situations such as a heart attack or when symptoms like chest pain are linked to a narrowed artery. Clinicians usually look at symptoms, test results, and imaging before deciding whether a stent, medicine, bypass surgery, or another approach fits.
Diagnosis often involves a conversation about personal and family history, a physical exam, bloodwork, an electrocardiogram, and sometimes stress testing or imaging of the arteries. A procedure called coronary angiography may show where arteries are narrowed.
After a stent, care has traditionally included follow-up visits, medicines chosen by the treating clinician, and attention to lifestyle and risk factors. Cardiac rehabilitation programs are often part of this, and each person's plan is individual. Coverage for procedures and testing varies by insurer, state, and diagnosis, so it helps to confirm with your insurer and provider.
How the right cardiologist may help
The right cardiologist may help you understand why a stent is or is not being discussed, what your tests show, and what the alternatives might be. A visit generally includes a review of your symptoms, medical history, and family history, followed by an exam and possibly tests.
You might ask: What did my tests find? Is a stent, medicine, or surgery being considered, and why? What are the possible benefits and risks for someone like me? What will recovery and follow-up look like? A good cardiologist may explain things in plain language and welcome a second opinion.
If heart disease runs strongly in your family, you may also ask whether genetic counseling or genetic heart testing could be relevant. A cardiologist or genetic counselor may help interpret results alongside your history and imaging. Ask about GINA too: it protects against genetic discrimination in health insurance and employment in the US, but it does not cover life, disability, or long-term-care insurance, so ask about those before testing.
The whole-person view
Body, mind, and stress affect one another. Learning that you may need a heart procedure can bring worry, fear, or a sense of being overwhelmed, and ongoing stress may in turn affect how people sleep, eat, and move. Many people find that caring for the whole person is part of feeling steadier before and after a cardiac event.
Some people look to body-based support such as Somatic Experiences to help them tune in to how stress lives in the body. Others find talk therapy through Therapists.plus helpful for processing fear or life changes after a heart event. These can sit alongside, never replace, the care of your cardiology team.

- Licensed professionals should guide care for coronary artery disease and heart attack, and no test or procedure can promise to prevent a future heart attack or sudden cardiac death.
- If you think you are having a heart attack, such as chest pain or pressure, shortness of breath, or pain spreading to the arm or jaw, call 911 right away.

Frequently asked questions
What is a heart stent procedure?
A heart stent procedure is a minimally invasive way a cardiologist may place a small mesh tube in a narrowed coronary artery to help keep it open. A catheter is guided to the heart, usually through a blood vessel in the wrist or groin. Whether it is right for you is decided by a licensed clinician after an evaluation.
Why would someone need a heart stent?
A stent may be considered when a coronary artery is narrowed or blocked, such as during a heart attack or when symptoms are tied to a narrowing. Clinicians weigh symptoms, test results, and imaging before choosing between a stent, medicine, surgery, or other approaches. Your cardiologist can explain what applies to you.
Is a heart stent procedure considered major surgery?
A stent procedure is generally described as minimally invasive because it uses a catheter rather than open-chest surgery. It still carries risks and requires a medical team, so it is not something to take lightly. Ask your cardiologist what to expect in your situation.
Are heart stents FDA regulated?
Yes, coronary stents are medical devices regulated by the FDA in the United States. Different stent types exist, and a clinician chooses based on your evaluation. It is reasonable to ask your provider about the specific device being used and its regulatory status.
What happens after a heart stent procedure?
Aftercare generally involves follow-up visits, medicines directed by your clinician, and often a cardiac rehabilitation program. Plans are individual, so follow your care team's guidance. Ask your cardiologist what recovery and long-term follow-up may look like for you.
Can genetic heart testing tell me if I need a stent?
No, genetic heart testing cannot tell you whether you need a stent. Genetic tests show risk or carrier status and do not diagnose heart disease on their own. A negative result does not rule out risk, and a variant of uncertain significance is not a diagnosis. Genetic counseling before and after testing is recommended, and family (cascade) testing may be suggested if a disease-causing variant is found.
