Abstract In the treatment of homozygous and therapy-resistant hypercholesterolemia, lipid apheresis enables not only low density lipoprotein (LDL) cholesterol to be lowered by approximately 60%, but also oxidative stress factors to be influenced and adhesion molecules reduced. This was investigated in a group of 12 patients using the heparin-induced extracorporeal LDL precipitation (H.E.L.P.) procedure. A significant lowering of LDL cholesterol and fibrino-gen leads to an improvement in rheology and endothelial function, detectable and measurable within approximately 20 h by assessing minimum coronary resistance using posi-tron emission tomography (PET) performed in 35 patients. This effect is detectable even after the first lipid apheresis session (H.E.L.P. procedure), documented in 12 patients. Lipid apheresis appears to be the most effective proce-dure in the treatment of elevated lipoprotein(a) [Lp(a)]. A chosen group of nine patients with selective elevated Lp(a) illustrated both the influence on endothelial dysfunction, in the shape of sharply increased minimum coronary resist-ance, and the reduction through lipid apheresis, indicating that Lp(a) seems to exert a similar effect on the vascular wall and vascular function as LDL cholesterol
