World Heart Day Special

Heart trauma leaves scar tissue, interrupting the heart's ability to pump blood efficiently. While the human heart cannot repair itself after a heart attack or other types of damage, the hearts of other species seem to be able to. Fish, for instance, can regenerate cardiac muscles.  Inspired by this, a team of researchers led by Stanford University's Professor Dr. Pilar Ruiz-Lozano decided to test these species' heart cells to determine which compounds stimulate healing. We invite Dr. Pilar Ruiz-Lozano and Professor Mark Mercola to share their findings.
