Blood flow to the heart often is interrupted during a heart attack or cardiac surgery. But when blood flow resumes, the heart may still falter. That's because collateral damage can occur as blood re-enters the heart, potentially slowing recovery and causing future cardiac troubles. Researchers investigating this type of secondary heart damage have been stymied by the inability to see in real time how restoring blood flow leads to inflammation that can cause further injury. Now, working in mice, surgeons and scientists at Washington University School of Medicine in St...
