What is a Stent?
DefinitionIn coronary stenting, a mesh, metal tube is placed in an artery in the heart. The tube is called a stent. It helps to keep the artery open. It is placed after an artery has been cleared of blockage during an angioplasty . There are two types of stents. One is called a drug-eluting stent. It is coated with a medication that is slowly released. The medication helps decrease the rate of reblockage in the artery. The other type of stent is called a bare-metal stent. It does not contain any medication. Your doctor will discuss which stent option is best for you.

Reasons for ProcedureThis procedure is done to hold open a previously blocked artery in the heart. This will allow more normal blood flow through that artery.After the stenting, your artery should be more open. This will allow better blood flow to feed the heart muscle. It may mean that you will no longer have chest pain. Your tolerance for exercise may increase.
