A drug-eluting stent (DES) is a small mesh tube that is placed in the arteries to keep them open in the treatment of vascular disease.The stent slowly releases a drug to block cell proliferation (a biological process of cell growth and division), thus preventing the arterial narrowing that can occur after stent implantation.
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. The vast majority of stents used in modern interventional cardiology are drug-eluting stents (DES).
Stenting refers to the placement of a stent.

A stent is different from a shunt. A shunt is a tube that connects two previously unconnected parts of the ...
A heart attack during or shortly after the procedure occurs in 0.3% of cases; this may require emergency coronary artery bypass surgery. [13] Heart muscle injury characterized by elevated levels of CK-MB, troponin I, and troponin T may occur in up to 30% of all PCI procedures. Elevated enzymes have been associated with later clinical outcomes ...
Usually, patients receive medication that will relax them to protect the arteries against spasms. Patients are typically able to walk within two to six hours following the procedure and return to their normal routine by the following week. [32] Angioplasty recovery consists of avoiding physical activity for several days after the procedure.
Recovery after carotid artery stenting depends not only on the presence of complications during the procedure, but also on the presence of symptoms at the time of arrival to the hospital. Asymptomatic patients typically leave the hospital in 0–1 days. The blood pressure is kept at a goal below 140 mmHg systolic.
