About Heparin toxicity.

Heparin toxicity is an adverse clinical state resulting from excessive anticoagulation due to heparin administration or overdose, primarily affecting the vascular and hematologic systems.

Pathophysiologically, supra-therapeutic circulating levels of heparin excessively potentiate antithrombin III, leading to profound inhibition of factor Xa and thrombin and resulting in impaired secondary hemostasis.

The condition is clinically defined by markedly prolonged coagulation parameters—such as the activated partial thromboplastin time or anti-factor Xa levels—and manifests predominantly as minor to life-threatening hemorrhage, including gastrointestinal, retroperitoneal, intracranial, or post-procedural bleeding.
