Stents - GCSE Biology Definition

Stents are small mesh tubes, usually made of metal, that are inserted into narrowed or blocked arteries to keep them open. They are often used in coronary arteries, which supply the heart muscle with oxygen-rich blood. If these arteries become too narrow, it can reduce blood flow and lead to serious conditions like heart attacks. A stent is placed in the artery using a procedure called angioplasty. Once in place, the stent helps restore normal blood flow and reduce the risk of further heart problems. Stents are an example of a medical treatment used to manage cardiovascular disease.
