Plasmin-antiplasmin complexes
proteinPlasmin-antiplasmin complexes quantify active fibrinolysis of the coronary thrombus, indicating both thrombus formation and the fibrinolytic response in acute MI.

RationalePlasmin generation marker; reflects fibrinolytic activity and endogenous thrombus breakdown.
Druggability
Not assessed (no mapped human gene target).
Type I vs Type II discrimination
ScoresLow-confidence (proxy)
R — rupture / Type-I54
C — confounder / Type-II45
A — assay feasibility68
E — evidence strength22
