S100A8 and coronary artery disorder: Coronary artery disease patients with CagA display more extensive damage of the coronary artery lumen and more frequently post-percutaneous transluminal coronary angioplasty (PTCA) with stent insertion re-stenosis of the coronary artery; and a H. pylori eradication regimen improves the reduction in the coronary artery lumen in these post-PTCA patients, possibly owing to the reduction of H. pylori pro-inflammatory cytokine release and the attenuation or elimination of H. pylori-induced chronic inflammatory prosses [102].
