Heparin-induced extracorporeal low-density lipoprotein (LDL) precipitation (HELP) is a selective and careful apheresis procedure. Through the application of heparin and lowering the pH value, lipoproteins and fibrinogen are reduced by 50-60%. In addition, adhesion molecules (ICAM-1, VCAM-1, p-selectin) which play a key role in the development and progression of atherosclerosis, are also markedly reduced. A PET scan performed 20 h after LDL apheresis shows the improvement of coronary vasodilation capacity. This is supposed to be mainly due to the marked reduction of LDL cholesterol and fibrinogen with consecutive improvement of endothelial dysfunction and rheology.

Hemostasis is a crucial process that prevents excessive blood loss from damaged blood vessels. It involves various mechanisms such as vasoconstriction, platelet adhesion and activation, and fibrin formation. The importance of each mechanism depends on the type of vessel injury. In contrast, thrombosis is the abnormal formation of a blood clot within the blood vessels, leading to potential complications if the clot obstructs blood flow. Thrombosis can be caused by increased coagulability of the...
