The first person to receive a new cardiac stem cell treatment in a U.S. Food and Drug Administration clinical trial is doing well, it was announced last week.
On Friday, doctors at the University of Louisville School of Medicine, in collaboration with the nearby Jewish Hospital, issued a press release stating that one week after treatment, Mike Jones’s heart was getting stronger.
Jones, whose heart tissue is permanently scarred and weakened by two previous heart attacks, suffers from congestive heart failure, a condition affecting about five million Americans each year, according to the National Institutes of Health.

Even though heart attacks may not be deadly, they can leave your ticker damaged. The reason: they occur when blood flow to a section of heart muscle becomes blocked. If the flow of blood isn't restored quickly, a section of the heart muscle becomes damaged from the lack of oxygen and begins to die, weakening its ability to pump blood.
Researchers have long wondered whether such damage could be reversed, that is, whether hobbled heart muscle cells could regenerate — potentially affecting the ability of scientists to hatch ways to repopulate damaged heart tissue. A study in Science today confirms that some heart muscle cells do, in fact, regenerate slowly over the course of a person's lifetime. Scientists from the Karolinska Institute in Sweden report that in early adulthood, we're continually renewing about 1 percent of our heart cells a year; that regeneration slows down, but it still occurs in old age, with a little less than half of 1 percent of cells regenerating at age 75. All told, we've renewed about 40 percent of our heart cells by age 70, neuroscientist Jonas Frisén told Science in a podcast.
