Use stem cells to restore damage caused by heart attack

Experts have used stem cells to regenerate heart muscle in patients who have just had a heart attack.

Dr. Eduardo Marbán said he will continue to conduct a larger-scale study later this year

The results were drawn from a study conducted by Tim Cedars-Sinai Institute in Los Angeles (USA) that performed more than 25 patients who had had a previous heart attack from 1 1/2 months to 3 months.

Among them, 17 patients received stem cell transplantation from the heart muscle tissue of the patients themselves, and the remaining 8 patients were treated according to the current conventional method.

When a heart attack occurs, the cell is damaged and scarred. After the treatment period, the size of scars in stem cell transplant patients decreased from 24% to 12% from the original shape, according to the director of the Tim Cedars-Sinai Eduardo Marbán Institute.

According to a report by The Lancet, Dr. Marbán said that stem cells patched the damaged heart muscle indirectly, by stimulating the cardiac endogenous recovery mechanism.

The most unexpected result after the study was that cardiac detection specialists were able to reproduce healthy cells, contrary to previous inferences that heart scars cannot recover.
