Whereas reperfusion can restore cardiac perform, such sudden infusions of oxygen also can additional injure severely depleted areas of the center. "It is a double-edged sword," says Anthony McDougal, a graduate scholar in MIT's Division of Mechanical Engineering. "The fast return of oxygen is critical for the center to outlive, nevertheless it may additionally overwhelm the center."
