Abstract
Recent interest has focused on superoxide and the upregulation of NADPH oxidase expression in the aetiology of vein graft failure. Implantation of saphenous vein grafts promotes upregulation of NADPH oxidase through a number of distinct interrelated mechanisms: (a) endothelial denudation, (b) factors released by adherent platelets, monocytes and neutrophils, (c) hypoxia and (d) altered prostacyclin (PGI(2)) and enhanced isoprostane formation. These, in turn, impact on neointima (NI) formation (vascular smooth muscle cell [VSMC] replication and migration) and metalloproteinase (MMP) expression, key events in vein graft thickening. NADPH oxidase in the aetiology of vein graft failure will be discussed in this review with particular reference to nitric oxide and eicosanoids and related drugs that inhibit its activity and expression.Entities:
