Stem cells improve heart function in patients with heart failure
Heart disease is one of the leading causes of death in the United States, with nearly 700,000 people dying each year from the condition. For decades, researchers have been exploring the potential of stem cells to restore damaged hearts and improve patient outcomes. A recent study by the Texas Heart Institute has shown some promise in this area, although more research is needed before this approach can be widely adopted.
Stem cells are cells that can turn into a variety of other cells, and they have the potential to regenerate damaged or diseased tissues. In the Texas Heart Institute study, researchers used mesenchymal stem cells, which can turn into bone, cartilage, muscle, and fat, to decrease inflammation around the heart in patients with heart failure. The study involved 565 heart failure patients, half of whom were given high doses of mesenchymal stem cells and the other half a sham procedure.
While the study did not show a statistically significant improvement in hospitalization or time until death for the treated patients, those who received the cells had a 58% reduced risk of heart attack or stroke, with the risk reduction rising to 75% for patients with high levels of inflammation. The cells also improved heart function, with the hearts pumping stronger after a year of treatment. The improvements seen in the study came on top of existing medication therapies.
The study’s lead researcher, Dr. Emerson Perin, said that he now has a better understanding of how mesenchymal stem cells work to improve heart function, and he has a clear path forward to conduct another clinical trial. He said, “I now have the recipe. I know who I have to give (the cells) to, how I have to give them and in what dose.”
While the study’s findings are promising, experts caution that there is still a long way to go before stem cell therapy can be widely used to treat heart failure. Dr. Richard Lee, a stem cell biologist at Harvard University, notes that drugs already available to treat heart failure are underused, and doctors should not wait for newer therapies. Dr. Roberto Bolli, a cardiology expert, says that while the study’s findings are significant, the slow progress in stem cell research can be attributed in part to a lack of funding. Misinformation about new therapies is another factor also.
In conclusion, the recent study by the Texas Heart Institute has shown some promise in using mesenchymal stem cells to improve heart function in patients with heart failure. While more research is needed to refine this approach and demonstrate its effectiveness, the study provides a new glimmer of hope for patients with heart disease, which remains a major health concern.
