It is a sad fact that around one in every four people who are hospitalized for heart failure does not live for more than a year. According to a study by University of California, a drug named Serelaxin has increased the survival rate to approximately 37 percent.
It is a synthetic version of the hormone relaxin which is basically produced by pregnant women to cope with the stress carrying a fetus places on the heart. This hormone not only opens the blood vessels but it also has anti inflammatory properties.
In humans, relaxin also has been shown to improve blood flow and cut down on inflammation, so scientists thought it might help fight heart failure.
In heart failure, the heart is damaged (often by a heart attack) and becomes inefficient, leading to chronic weakness and shortness of breath. The condition is often fatal, and there has been no real advance in treating the disease for decades.
