[单项选择]Stem Cell Therapy May Help Repair the Heart
According to scientists in the USA，stem cell therapy may one day be able to repair the hearts of people with heart failure．Researchers at Pittsburgh University School of Medicine examined 20 patients who had severe heart failure and were going to have surgery．
They injected stem cells into the parts of their hearts that were damaged，They then compared their hearts with those of people who had undergone surgery without having the stem cells injected into them(they had also suffered from severe heart failure)．The patients who had had the stem cells injected had hearts that were able to pump(用泵抽运)more blood than the others．
According to Professor Robert Kormos，one of t11e researchers，these results could revolutionize heart treatment．Although previous studies had indicated that there might be a benefit，this is the first study that has actually proved that stem cell therapy can help the failing heart work better．
