What is one consequence of decreased α2-antiplasmin levels in the body?

• A. Increased clot retention
• B. Increased risk of hemorrhage
• C. Increased fibrinolysis
• D. Decreased platelet aggregation

Answer: (C)

Decreased levels of α2-antiplasmin in the body lead to increased fibrinolysis. α2-Antiplasmin is a key inhibitor of plasmin, the enzyme responsible for breaking down fibrin in blood clots. When the concentration of α2-antiplasmin is reduced, there is less inhibition of plasmin, allowing it to more readily break down fibrin. This results in enhanced fibrinolytic activity, leading to faster and potentially excessive breakdown of clots within the bloodstream. This process can have significant physiological implications, especially in situations where hemostasis is crucial, as it may lead to a reduced ability to maintain clots at sites of vascular injury, effectively compromising the body's ability to stop bleeding.
