CD40LG and coronary artery disorder: Plasma levels of IgM against the A2M824–841 MDA-modified peptides among patients with CAD with >70% stenosis were lower than those of HCs by 0.54-fold (p < 0.0001), patients with CAD with 30~70% stenosis were 0.69-fold (p = 0.002) lower than HCs, and patients with CAD with <30% stenosis were 0.65-fold (p = 0.001) lower than HCs (Supplementary Figure S2E, right panel).
