Human Heart Researchers at the Stanford University School of Medicine have found that a reinforcing band could help prevent expansion of the heart, thereby reducing the danger of congestive heart failure tools.

Basically, congestive heart failure occurs when the heart cannot pump enough blood to meet the bodyís metabolic needs which is generally thought to be caused by problems with the heartís valves or damage to its walls.

In order to compensate in the short time, the heart tries to expand so that it can pump in more blood. But, this starts a vicious cycle of decline that damages the overstretched heart even more.

The study that was lead by Bilal Shafi found that a protective band made from two different polymers, 740 and 742, around the heart could help to prevent the organ from becoming enlarged by reinforcing its walls.

The Stanford researchers also suggested that two layers of polymer should build the walls of the heart.

The first layer is made of polyethylene glycol to provide strength, and the second layer of collagen that would provide elasticity and biocompatibility.

The ability to deliver polymer mix to the heart in the form of a powder or gel is the key to the technique. UV light or heat to form a thin, strong film can secure it in place.
