Genetic Influences Independent Acceleratorseg hypertension, lipids, smoking
Hyperglycaemia
Metabolic Factors Haemodynamic FactorsGlucose Toxicity Angiotensin II/renin angiotenin systemGlycation EndothelinPolyol Pathway Nitric oxideHexosamine Pathway
Growth Factors / Cytokines Intracellular FactorsTGF-β, VEGF, AGII, DAG-PCK, MAPK NFĸBCTGF, GH, IGF-1
Diabetic Vascular Disease
Hyperglycaemia
Increased mitochondrial ROS
DNA strand breaks
Activation of PARP
Inhibition of GAPDH
Accumulation of glycolytic intermediates upstream of GAPDH
Increased polyol and hexosamine flux, glycation, DAG-PKC
