What is the role of a stent in PCI?

Explanation:
The stent serves as a scaffold inside the artery, holding the vessel open after balloon angioplasty so the widened lumen stays maintained as the artery heals. This prevents recoil and reduces the chance of restenosis, helping to keep blood flow improved over time. It does not remove plaque, measure blood flow, or deliver oxygen. After placement, antiplatelet therapy is usually needed to prevent stent-related thrombosis; drug-eluting versions can further reduce the risk of restenosis by limiting the growth of scar tissue inside the artery.
