title: Fletcher factor deficiency and myocardial infarction.
abstract: The case of a patient who, while being treated for an acute myocardial infarction, was found to have Fletcher factor deficiency with a Fletcher factor concentration of less than 1% of normal is described. Fletcher factor deficiency is associated with defects in several interrelated systems, including clotting, fibrinolysis and kinin generation, all of which play a role in the pathogenesis and evolution of infarction. The development of myocardial infarction in a patient who had severe Fletcher factor deficiency emphasizes the importance of alternate pathways for activation of these systems.
