SN instructed patient on stents. A stent is a tiny wire mesh tube. It props open an artery and is left there permanently. When a coronary artery (an artery feeding the heart muscle) is narrowed by a buildup of fatty deposits called plaque, it can reduce blood flow. If blood flow is reduced to the heart muscle, chest pain can result. If a clot forms and completely blocks the blood flow to part of the heart muscle, a heart attack results.
SN instructed patient about stents help keep coronary arteries open and reduce the chance of a heart attack. 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. Then the balloon is removed and stent stays in place. This holds the artery open and allows blood to flow more freely.
