Research Abstract

Cardiovascular disease (CVD) is a major cause of death in patients with chronic kidney disease (CKD). Patients with CKD are reported to have a significant greater risk of CVD-associated mortality than that of the general population. Low-density lipoprotein (LDL) apheresis is a potentially valuable treatment applied to conventional therapy-resistant hypercholesterolemic patients with coronary artery disease and peripheral artery disease (PAD). Although previous and recent studies have suggested that LDL apheresis exerts beneficial effects on the peripheral circulation in dialysis patients suf- fering from PAD, probably through a reduction of not only serum lipids but also of inflammatory or coagulatory factors and oxidative stress, the precise molecular mechanisms underlying the long-term effects of LDL apheresis on the improvement of the peripheral circulation remains unclear and warrants further investigation, including a possible role of Ang II receptor-interacting molecule, ATRAP.
