Overview
Thrombophilias are classified as either inherited or a primary hypercoagulable state, acquired or a secondary hypercoagulable state, or mixed/unknown. Certain conditions are associated with greater thrombotic risks and both venous and arterial clots.
Classification
- Thrombophilia can be classified in various forms[1].
- Inherited thrombophilia or primary hypercoagulable state
- Acquired thrombophilia or secondary hypercoagulable state
- Mixed/Unknown
- Different thrombophilic states are associated with venous or both venous and arterial clots
Thrombophilia Classification | ||
---|---|---|
Inherited (Primary) | Acquired (Secondary) | Mixed/Unknown |
Activated protein C (APC) resistance (Factor V Leiden) | Age | Hyperhomocysteinemia |
Prothrombin gene mutation (Prothrombin G20210A) | Immobilization | APC resistance unrelated to Factor V Leiden. |
Antithrombin deficiency | Trauma/major surgery | Increased factor VIII levels |
Protein C and protein S deficiency | Orthopedic surgery | Increased factor XI levels |
Dysfibrinogenemia | Malignancy | Increased factor IX levels |
Myeloproliferative disorders (polycythemia vera, essential thrombocythemia, hyperviscosity) | Increased levels of thrombin-activatable fibrinolysis inhibitor (TAFI) | |
Pregnancy | Decreased levels of free tissue factor pathway inhibitor (TFPI) | |
Estrogen and testosterone (oral contraceptives and hormone replacement therapy) | ||
Obesity | ||
Heart Failure | ||
Cirrhosis | ||
Chronic renal disease (nephrotic syndrome) | ||
