A stent is a medical device used to open blocked or narrowed blood vessels. It is an important tool in managing heart disease and has saved countless lives. There are different types of stents available, such as balloon-expandable stents, self-expanding stents, and drug-eluting stents. While "stent" is the most common term used in the medical field, there are synonyms that describe the same device, such as vascular stent, coronary stent, intravascular stent, and angioplasty stent. Regardless of the name used, stents play a significant role in preventing heart attacks and improving patient outcomes.
