A coronary stent is a small tube-shaped device placed in a coronary artery during percutaneous coronary intervention to keep the artery open in a person with coronary heart disease. Most stents used today are drug-eluting rather than plain bare metal, releasing medication that helps prevent the artery from renarrowing, and stents have been shown to reduce angina, improve survival and lower the rate of further adverse events after a heart attack.

FAQs
Why are blood-clot-preventing medicines often prescribed after a stent?
Antiplatelet medicines such as aspirin prevent blood clots that can block an artery stent.
The National Heart, Lung, and Blood Institute explains that after a stent is placed, a person may need antiplatelet medicines such as aspirin, which prevent the blood from forming clots. Depending on where the stent sits, a healthcare provider may recommend taking such a medicine for a year or longer to prevent complications. The most common problems it names are a stent becoming blocked, a blood clot forming in an artery stent, or an airway stent moving out of place. This describes what the source says and is not medical advice.

A coronary stent is a tube-shaped device placed in the coronary arteries that supply blood to the heart to keep the arteries open in patients suffering from coronary heart disease.
Treats: Angina Pectoris, Lead
Stents reduce angina (chest pain) and have been shown to improve survival and decrease adverse events after a patient has suffered a heart attack-medically termed an acute myocardial infarction.

Treats: Atherosclerosis, Lead
Similar stents and stenting procedures are used in atherosclerosis of arterial vessels of the limbs-particularly in the legs, such as in peripheral artery disease.
