Coronary artery stents, typically a metal framework, can be placed inside the artery to help keep it open. However, as the stent is a foreign object (not native to the body), it incites an immune response. This may cause scar tissue (cell proliferation) to rapidly grow over the stent and cause a neointimal hyperplasia.
If restenosis occurs within a stent (also known as in-stent stenosis), it may be treated with repeated angioplasty and insertion of another stent inside the original, often with a drug-eluting stent. [14] Over the past 5 years, ISR has been increasingly treated with a drug-coated balloon (DCB), which is a balloon coated with the same anti ...

Vascular stents are commonly used in angioplasty, a surgical procedure that opens blocked arteries and places a stent to keep the artery open. This is a common treatment for heart attacks and is also used in the prevention and treatment of strokes. Over 2 million people receive a stent each year for coronary artery disease alone.
For some high-risk cardiovascular patients with stents, the often-recommended practice of prolonged taking of aspirin might be ineffective, and in some cases, even harmful, a new study found.
The first two drug-eluting stents to be utilized were the paclitaxel-eluting stent and the sirolimus-eluting stent, both of which have received approval from the U.S. Food and Drug Administration. Most current FDA-approved drug-eluting stents use sirolimus (also known as rapamycin), everolimus and zotarolimus.
A dual therapy stent is a coronary artery stent that combines the technology of an antibody-coated stent and a drug-eluting stent. [1] Currently, second-generation drug-eluting stents require long-term use of dual-antiplatelet therapy , which increases the risk of major bleeding occurrences in patients. [ 2 ]
