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
