BCAA consists of the amino acids leucine, isoleucine and valine. The reason these three amino acids are called BCAA is because they branch off from the other five essential amino acids, (there are a total of eight), to create their own chain. Amino acids are responsible for the formation of proteins in the body.
An aneurysm is an abnormal bulging out or ballooning of a portion of the artery, usually due to weakness of the arterial wall. The aneurysm may enlarge and rupture, often with disastrous consequences.
A stent is a wire metal mesh tube used to prop open an artery during angioplasty. The stent is collapsed to a small diameter and put over a balloon catheter. Itâs then moved into the area of the blockage. When the balloon is inflated, the stent expands, locks in place and forms a scaffold. This holds the artery open.
