Flashcards

Hypercoagulability

A condition where the blood clots too easily, either due to inherited genetic factors or acquired factors like surgery, pregnancy, or certain medications.

Hereditary Hypercoagulability

A type of hypercoagulability caused by mutations in genes involved in blood clotting, such as Factor V Leiden or Prothrombin.

Acquired Hypercoagulability

A type of hypercoagulability that develops due to external factors like surgery, pregnancy, or certain medications.

Heparin-Induced Thrombocytopenia (HIT)

A condition where antibodies against platelets are produced after exposure to certain types of heparin, leading to increased clotting.

Antiphospholipid Antibody Syndrome (Lupus Anticoagulant Syndrome)

A condition where antibodies targeting phospholipids are produced, leading to blood clots, low platelet counts, and potential miscarriages.
