Role of Neutrophils in Ischemia/Reperfusion Injury during Heart Surgery.

To test the hypothesis that neutrophils play a role in ischemia/reperfusion injury during heart surgery, granulocyte elastase and myeloperoxidase release from coronary circulation were measured before and after aortic cross-clamping. The production of granulocyte elastase and myeloperoxidase across the coronary circulation elevated significantly after release of aortic cross-clamp. Furthermore, the level of granulocyte elastase and myeloperoxidase released from coronary circulation demonstrated positive correlation with the duration of the aortic cross-clamp. These data indicate that neutrophils play a major role in ischemia/reperfusion injury occurring during heart surgery.
