Coronary Stents
Coronary stents are tiny, expandable metal mesh tubes implanted in narrowed or blocked coronary arteries to restore blood flow to the heart. They serve as scaffolding to keep arteries open, preventing recurrent blockages. Stents can be bare-metal or drug-eluting, releasing medications to inhibit cell proliferation and reduce restenosis. Commonly used in percutaneous coronary intervention (PCI), stents are inserted via a catheter and deployed at the blockage site. Risks include clot formation, bleeding, and allergic reactions. While stents effectively alleviate symptoms and improve outcomes in coronary artery disease, lifestyle changes and medication adherence are crucial for long-term management.
