The association between coronary artery disease and several infectious pathogens such as H. pylori was found to be modulated by the interleukin (IL)-6/G-174C polymorphism, this interaction being mediated by variations in serum IL-6 levels [20].On the other hand, a decreased foveal choroidal blood flow has been demonstrated by laser Doppler flowmetry and using fluorescein and ICG angiography with confocal scanning laser ophthalmoscopy. This evidence concerns the gene IL6 and coronary artery disorder.
