Coagulation cascade and fibrinolytic system

The coagulation cascade and fibrinolytic system represent a highly regulated network of serine proteases and cofactors that maintain vascular integrity by balancing clot formation and dissolution. The coagulation cascade is initiated via intrinsic or extrinsic pathways, leading to the generation of thrombin, which converts soluble fibrinogen into an insoluble fibrin mesh [1][3]. Conversely, the fibrinolytic system, primarily driven by plasmin, degrades these fibrin clots to prevent vessel occlusion and restore blood flow [2][4]. Dysregulation of this balance leads to pathological states such as thrombosis or excessive bleeding [3]. Pharmacological intervention typically targets specific enzymes within these pathways, such as Factor Xa or thrombin, to treat or prevent cardiovascular events, or utilizes plasminogen activators to dissolve existing clots in emergency settings like stroke or myocardial infarction [1][2].
