Study Notes
- Haemostasis involves vasoconstriction, primary and secondary haemostasis, and fibrinolysis.
- Tests to assess coagulation cascade include PT and PTT assays.
- Anticoagulation therapy includes Warfarin, Heparin, Clopidogrel, Aspirin, Tirofiban, and Alteplase.
- Warfarin inhibits Vitamin K reductase, while Heparin enhances activity of ATIII.
- Clopidogrel is an ADP receptor antagonist, while Aspirin irreversibly inhibits COX.
- Tirofiban is a GPIIb/IIIA receptor antagonist, while Alteplase cleaves plasminogen to plasmin.
- Adverse effects of anticoagulation therapy include haemorrhage, thrombocytopaenia, osteoporosis, nausea, dizziness, peptic ulcers, worsening asthma, and Reye's syndrome.
- Contraindications for anticoagulation therapy include pregnancy, liver disease, recent neurosurgery, active ulcer disease, uncontrolled bleeding, peptic ulcers, haemophilia, renal disease, and gout.
- PT measures the extrinsic pathway of coagulation, while APTT measures the intrinsic pathway.
- Alteplase is used for STEMI, ischaemic stroke, and PE, but has contraindications for recent haemorrhage and uncontrolled bleeding.
