The study led by Bilal Shafi found that a protective band made of two different polymers, 740 and 742, around the heart could help prevent it from becoming enlarged by reinforcing its walls.
The researchers suggested that two layers of polymer should build the walls of the heart, reports New Scientist.
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 cure it in place.
Congestive heart failure occurs when the heart cannot pump enough blood to meet the body's metabolic needs which is generally thought to be caused by problems with the heart's valves or damage to its walls.
In order to compensate in the short time the heart tries to expand so that it can pump more blood. But this starts a vicious cycle of decline that damages the overstretched heart even more.
