When Does Fibrinolysis Occur?

Fibrinolysis is the breakdown of fibrin within blood clots. There are two types of fibrinolysis, being primary and secondary fibrinolysis. Primary fibrinolysis occurs naturally and secondary fibrinolysis occurs due to an external cause such as medicine or a medical disorder.

What initiates fibrinolysis?

Fibrinolysis initiation is mainly dependent on the tissue-type plasminogen activator (t-PA). Together with its substrate plasminogen, t-PA binds fibrin and thereby leads to a fibrin-dependent proteolysis.

Is fibrinolysis a phase of hemostasis?

Fibrinolysis is a process that removes clots following hemostasis and clot retraction, preventing uncontrolled thrombosis and embolism. There are two types of fibrinolysis: primary fibrinolysis and secondary fibrinolysis.
