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 the treatment of coronary heart disease. It is used in a procedure called percutaneous coronary intervention (PCI). Coronary stents are now used in more than 90% of percutaneous coronary intervention procedures. Stents reduce angina (chest pain) and have been shown to improve survivability and decrease adverse events in an acute myocardial infarction. Coronary artery stents is typically a metal framework which is placed inside the artery to help keep it open. Similarly stents and these procedures are used in non-coronary vessels i.e. in the legs in peripheral artery disease.

Though the chances of having complications from a PCI are small, some serious complications include the development of arrhythmias, adverse reactions or effects of the dye used in the procedure, infection, restenosis, clotting, blood vessel damage, and bleeding at catheter insertion site.

Cardiology research Journals like Clinical Cardiology and Cardiovascular Medicine (CCCM) provides a global open access platform to put forth the ongoing research, reviews and techniques related to Coronary stenosis.
