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.
