Doctors say a new procedure that uses stem cells from a patient’s muscle to help repair scarred hearts could eventually reduce reliance on heart transplants. A patient at Christ Hospital in Cincinnati underwent the procedure Thursday in hopes if repairing damage caused by a prior heart attack. Doctors say 71-year-old Charles Emmerick of Middletown is sitting up in a chair Friday and could be ready to go home in four or five days. Emmerick joined a handful of patients worldwide who have received muscle-cell transplants in hopes of repairing their damaged hearts. In the process, stem cells are taken from the patient’s muscle and injected into the heart. Once there, it’s hoped that they will grow and improve the heart’s beating power.
