Discovery of Repair Process After Heart Attack Suggests Potential for New Treatment Strategy

Press_release_Rev.JPG

UCLA stem cell researcher Dr. Arjun Deb has discovered that some scar-forming cells in the heart, known as fibroblasts, have the ability to become endothelial cells (the cells that form blood vessels), and this study can point the way toward a new strategy for treating patients after a heart attack.

Cellular “Power Grid” Failure Triggers Abnormal Heart Rhythms After a Heart Attack

Heart attack survivors often experience dangerous heart rhythm disturbances during treatment designed to restore blood flow to the injured heart muscle, a common and confounding complication of an otherwise lifesaving intervention. Now a duo of Johns Hopkins researchers working with rat heart cells have shown that such post-heart attack arrhythmias are likely triggered by something akin to a power grid failure inside the injured cardiac cells.
