Stem Cell Study Shows Promising Results Against Heart Failure

THURSDAY, May 10 (HealthDay News) -- A new treatment that involves spinning bone marrow stem cells to enhance their healing potential may help people with advanced heart failure feel and function better, a small study suggests.
Researchers developed the treatment by culturing a patient's own bone marrow for 12 days. This process helped increase the amount of immune cells and stem cells that can differentiate into several different cell types, including heart cells. Those cells were then injected into heart muscle. The study was funded by treatment manufacturer Aastrom Biosciences.
According to the findings, this treatment was safe, helped repair the damaged heart muscle and reversed some heart failure symptoms, when compared to a placebo injection. The findings were to be presented Thursday at the Society for Cardiovascular Angiography and Interventions annual meeting, in Las Vegas....

......"The new study included 22 participants with advanced heart failure and an enlarged heart whose current medication regimen was no longer effective. They either received an injection of the stem cell therapy treatment into their heart muscles or a placebo shot. After 12 months, there were no complications and no difference in side effects among those who received the stem cells and the control group. That said, individuals who received the novel stem cell therapy did have a lower number of major heart-related events and were more likely to see improvements in their ability to walk without growing breathless. Those who received the stem cell treatment also showed marked improvements in their ejection fraction, which is a measure of how much blood leaves the heart with each pump.
"This study tells us that injecting stem cells into the heart muscle of a patient with chronic heart failure may be beneficial," says Dr. Sandeep Jauhar, director of the congestive heart failure program at Long Island Jewish Medical Center in New Hyde Park, N.Y. Typically, these individuals are treated with multiple medications, put on a low-salt diet and encouraged to get some exercise.
"The available medications are very effective and people live a lot longer than they used to because of the drugs we have developed," he said. But many people reach a ceiling in terms of how effective the medications are, he added.
"We do need a new way of treating heart failure if we want more improvement," said Jauhar, who added that it is too early to say whether the new stem cell therapy will fill that role. .......
