The alteration of coagulation in patients with thyroid dysfunction

Area of Science:

• Endocrinology
• Hematology
• Thrombosis Research

Background:

• Thyroid dysfunction's effect on hemostasis is complex, with reported bleeding and hypercoagulable states.
• Understanding the interplay between thyroid hormones and the coagulation cascade is crucial for clinical management.

Purpose of the Study:

• To review the current literature on the relationship between thyroid dysfunction and secondary hemostasis and fibrinolysis.
• To synthesize findings on how hyperthyroidism and hypothyroidism affect blood clot formation and breakdown.

Main Methods:

• Systematic review of recent scientific literature.
• Analysis of studies investigating coagulation and fibrinolysis markers in patients with thyroid disorders.

Main Results:

• Thyroid dysfunction is associated with significant alterations in fibrin generation and fibrinolysis.
• Hyperthyroidism generally correlates with enhanced coagulation and impaired fibrinolysis.
• Recent evidence suggests hypothyroidism may also be linked to reduced fibrinolytic activity, contrary to older findings.

Conclusions:

• Thyroid dysfunction demonstrably influences secondary hemostasis and fibrinolysis.
• Further large-scale prospective clinical studies are needed to fully elucidate these effects in overt and subclinical thyroid diseases.
