A drug-eluting stent is a small mesh tube coated with medication that is placed inside a narrowed coronary artery. The stent helps hold the artery open, while the drug coating helps reduce tissue growth inside the stent. It is usually placed during coronary angioplasty, also called percutaneous coronary intervention. Drug-eluting stents are commonly used to treat coronary artery disease and reduce the chance of restenosis.
read more about drugeluting stent ...A drug-eluting stent is used to improve blood flow through a coronary artery that has been narrowed by plaque. It can help treat symptoms caused by reduced blood flow to the heart, such as chest pain, and it may be used during certain heart attack treatments. The stent acts as a scaffold that keeps the artery open after the blocked area is widened. It does not cure coronary artery disease, so long-term heart care is still needed.
The stent is mounted on a balloon catheter and guided to the narrowed part of the artery. When the balloon expands, the stent opens and presses against the artery wall. After placement, the drug coating slowly releases medication that helps limit scar-like tissue growth inside the stent. The stent stays in the artery after the balloon and catheter are removed.
Drug-eluting stents and bare-metal stents both help hold an artery open. The difference is that drug-eluting stents have a medication coating designed to lower the risk of the artery narrowing again. Bare-metal stents do not have that drug coating and are used less often in current coronary procedures. The cardiologist chooses the stent type based on the patient’s artery, bleeding risk, medication needs, and overall treatment plan.
After a drug-eluting stent is placed, patients usually need antiplatelet medicine to reduce the risk of a clot forming in the stent. The exact medication plan and duration should come from the cardiologist. Follow-up care often includes cholesterol control, blood pressure management, diabetes care, smoking cessation, diet changes, exercise, and cardiac rehabilitation when recommended. Chest pain, trouble breathing, fainting, stroke symptoms, or heavy bleeding after the procedure needs urgent medical care.
Yes, most drug-eluting stents remain in the artery permanently. Over time, tissue grows around the stent and it becomes part of the artery wall.
Yes. Restenosis or a clot inside the stent can happen, though drug-eluting stents are designed to reduce restenosis risk. Taking prescribed medication and attending follow-up visits helps lower complications.
Patients are usually prescribed antiplatelet medicine after stent placement. Do not stop these medicines unless the cardiologist gives clear instructions.
Drug-eluting stents are commonly preferred because they reduce the chance of repeat narrowing in many patients. The best choice still depends on the patient’s condition, bleeding risk, and cardiologist’s judgment.
