  2. Essential thrombocythemia - Wikipedia

    en.wikipedia.org/wiki/Essential_thrombocythemia

    Hydroxycarbamide, interferon-α and anagrelide can lower the platelet count. Low-dose aspirin is used to reduce the risk of blood clot formation unless the platelet count is very high, where there is a risk of bleeding from the disease, and hence this measure would be counter-productive as aspirin-use increases the risk of bleeding. [3] [15 ...

    en.wikipedia.org/wiki/Heparin-induced...

    Heparin-induced thrombocytopenia (HIT) is the development of thrombocytopenia (a low platelet count), due to the administration of various forms of heparin, an anticoagulant. HIT predisposes to thrombosis (the abnormal formation of blood clots inside a blood vessel ).

  4. Mechanism of action of aspirin - Wikipedia

    en.wikipedia.org/wiki/Mechanism_of_action_of_aspirin

    Low-dose, long-term aspirin use irreversibly blocks the formation of thromboxane A 2 in platelets, producing an inhibitory effect on platelet aggregation. [13] This effect is mediated by the irreversible blockage of COX-1 in platelets, since mature platelets don't express COX-2.

  5. Aspirin - Wikipedia

    en.wikipedia.org/wiki/Aspirin

    Low-dose aspirin use irreversibly blocks the formation of thromboxane A 2 in platelets, producing an inhibitory effect on platelet aggregation during the lifetime of the affected platelet (8–9 days). This antithrombotic property makes aspirin useful for reducing the incidence of heart attacks in people who have had a heart attack, unstable ...

    For years, doctors recommended that older adults at a higher risk for heart attack or stroke take a low-dose aspirin once a day to lower their risk. Aspirin helps prevent blood clots from forming ...

  7. Thrombocythemia - Wikipedia

    en.wikipedia.org/wiki/Thrombocythemia

    In hematology, thrombocythemia is a condition of high platelet (thrombocyte) count in the blood. Normal count is in the range of 150 × 10 9 to 450 × 10 9 platelets per liter of blood, [1] but investigation is typically only considered if the upper limit exceeds 750 × 10 9 /L.

  8. Antiplatelet drug - Wikipedia

    en.wikipedia.org/wiki/Antiplatelet_drug

    Antiplatelet drugs alter the platelet activation at the site of vascular damage crucial to the development of arterial thrombosis. Aspirin and Triflusal irreversibly inhibits the enzyme COX, resulting in reduced platelet production of TXA 2 (thromboxane – powerful vasoconstrictor that lowers cyclic AMP and initiates the platelet release ...

  9. Plateletpheresis - Wikipedia

    en.wikipedia.org/wiki/Plateletpheresis

    In a typical set of rules, a platelet donor must weigh at least 50 kg (110 lb) and have a platelet count of at least 150 x 10 9 /L (150,000 platelets per mm³). [2] One unit has greater than 3×10 11 platelets. Therefore, it takes 2 liters of blood having a platelet count of 150,000/mm³ to produce one unit of platelets.
