“…[20][21][22][23][24][25][26][27][28][29][30][31] Although there are several differences in the pathogenesis of KD vasculopathy and atherosclerotic heart disease, several studies have also shown that patients with KD have an increased risk of premature atherosclerosis as assessed using flow-mediated dilatation of brachial artery or carotid intima media thickness. [19][20][21][22][23][24][25][26][27][28][29][30][31][32][33] Long-term vasculopathy in patients with KD is characterized by chronic inflammation, endothelial dysfunction, luminal fibroblast proliferation, and thrombosis. 1 Increased CD40L levels seen in patients with KD despite standard treatment, as was seen in our study, may be one of the potential mechanisms for cardiovascular injury in these patients.…”
