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.
