Abstract

Stents are small, expandable tubes essential in treating narrowed or weakened arteries, primarily in patients with cardiovascular diseases. These devices are pivotal in maintaining arterial patency, reducing symptoms such as angina, and preventing heart attacks. This article provides a comprehensive overview of stent technology, including their historical development, types, mechanisms of action, and clinical applications. It also discusses the advantages and limitations of stent usage and recent advancements aimed at enhancing their efficacy and safety. Through continuous innovation, stents have significantly improved patient outcomes in cardiovascular treatment, underscoring their vital role in modern medical practice.
