title: Complement activation and cardiovascular disease.
abstract: The mechanisms by which tissue injury after acute myocardial infarction occurs have not been fully elucidated, but considerable evidence suggests that activation of complement plays an important role in the pathophysiology. Reperfusion of the ischemic myocardium is strictly necessary to rescue the exposed tissue from eventual death. However, reversion of the blood supply is also associated with reperfusion injury contributing to tissue injury. Activation of the complement system has indisputable beneficial effects in the immune defense and in the clearance of damaged tissue and apoptotic cells, but excessive activation of the system may lead to uncontrolled tissue damage. This review focuses on the role of complement activation, with focus on the lectin pathway, endothelial dysfunction and cardiovascular diseases, including ischemic heart disease and diabetic angiopathy. Finally, potential therapeutic strategies targeting the complement system are discussed.
