Etiopathogenesis
This section has been translated automatically.

In addition to LDL, Lp(a) contains ApoB-100, a plasminogen-like Apo(a), which competes with the plasminogen for the binding sites on the exothelial cells (antiplasminogenic effect). High Lp(a) may inhibit local fibrinolysis in the endothelial region of the vessels. Lp(a) concentrations >30mg/dl are considered an independent atherosclerosis risk factor.
