Why the study?
Does apolipoprotein(a) isoform size influence the ability of lipoprotein(a) to inhibit fibrinolysis?
Population

Smaller apo(a) isoforms may enhance Lp(a)-mediated antifibrinolysis; leaves open isoform-specific thrombotic risk in patients.
Does apolipoprotein(a) isoform size influence the ability of lipoprotein(a) to inhibit fibrinolysis?
Smaller apo(a) isoforms have a higher affinity for fibrin and more efficiently inhibit plasminogen activation, providing a mechanistic link between elevated Lp(a) levels and increased thrombotic risk.
Hervio et al. (1993) studied this question.
