A heart attack happens if the flow of oxygen-rich blood to a section of heart muscle suddenly becomes blocked and the heart can't get oxygen. Most heart attacks occur as a result of coronary heart disease (CHD). CHD is a condition in which a waxy substance called plaque builds up inside of the coronary arteries.
Stents help keep coronary arteries open and reduce the chance of a heart attack. A stent is inserted into the clogged artery with a balloon catheter. The balloon is inflated and the stent expands and locks in place. This holds the artery open and allows blood to flow more freely.
A stent is a small mesh tube that's used to treat narrow or weak arteries. Arteries are blood vessels that carry blood away from your heart to other parts of your body. A stent is placed in an artery as part of a procedure called per-cutaneous coronary intervention (PCI), also known as coronary angioplasty.
