Clinical trials of cardiac stem cell therapy experiments have yielded results
British medical journal the Lancet study published online on 14th, the report says, American researchers with cardiac stem cell therapy in the treatment of myocardial infarction clinical trials to obtain results.
Researchers at the university of louisville, institutions such as the United States, the report says, there are 16 patients with myocardial infarction accepted the stem cell therapy. Myocardial infarction is due to reasons such as cardiovascular function is impaired, myocardial ischemia caused by a series of symptoms, now commonly used cardiovascular bypass surgery to alleviate symptoms, namely artificial connection section of blood vessels, for ischemic myocardial blood supply. The study in the use of stem cells, derived from the bypass surgery to retrieve heart tissue.
Stem cells are cells that have not yet fully developed into adult cells and have the potential to grow into specific organs. The researchers cultured the stem cells in test tubes and injected large Numbers of them back into their owners' hearts about four months later, expecting them to grow into new healthy heart tissue.
The results showed that the chance of the left ventricle pumping blood out of the ventricle normally in a single heartbeat had dropped to 30.3% because of damage to the heart muscle, but after stem cell treatment that number rose to 38.5%.
Researcher Roberto Boli said the results were surprising and could be a major step forward for cardiovascular medicine if follow-up studies further support the effectiveness of the cardiac stem cell therapy.
