Stents are small, expandable tubes that treat narrowed arteries in your body. In people with coronary heart disease caused by the buildup of plaque, they can:

1. Open narrowed arteries
2. Reduce symptoms, like chest pain
3. Help treat a heart attack

These types are called heart stents, but they’re also referred to as cardiac stents or coronary stents. Usually made of metal mesh, they’re put into arteries in a procedure called a percutaneous coronary intervention or, its more common name, angioplasty.

Performed with local anesthesia and mild sedation, angioplasty involves no major incisions and usually takes about an hour. If you need more than one stent, it can take longer.

Compared to coronary artery bypass surgery, which is much more invasive, people who get stents have less discomfort and shorter recovery time.

But stenting isn’t risk-free. A blood clot can form in one and cause your arteries to narrow again suddenly. It may even cause a complete blockage. To prevent this, people take one or more blood-thinning drugs after they get a stent. These can include aspirin, which usually must be taken indefinitely, and clopidogrel (Plavix), prasugrel (Effient), or ticagrelor (Brilinta), which are usually prescribed for at least 1 and up to 12 months.

Scar tissue or plaque can also form in the area of your stent. This can cause your artery to narrow again over a period of months. Your doctor may call this restenosis. If it happens, another stent can often solve the problem. In some cases, coronary artery bypass surgery may be needed.

    Great stuff! A stent is a tiny wire mesh tube. It props open an artery and is left there permanently. When a coronary artery is narrowed by a buildup of fatty deposits called plaque, it can reduce blood flow. Stents help keep coronary arteries open and reduce the chance of a heart attack. Thanks and keep posting things like this.

    A stent is a tiny wire mesh tube that is inserted into a narrowed or blocked coronary artery. Yes, this is very effectively explained that if a coronary artery narrows, you may develop symptoms of angina, such as chest pain, shortness of breath, a cold sweat, and lightheadedness. A heart attack strikes when plaque breaks open and causes the formation of a blood clot in a partially clogged artery and completely blocks blood flow. That’s when a stent can be lifesaving.
