Inhibition of 12-lipoxygenase reduces platelet activation and prevents their mitogenic function.

abstract：:Outcomes of platelet function tests are highly dependent on the type of blood anticoagulant used. The primary objective of this study was to clinically evaluate the platelet function after dual antiplatelet therapy using two different types of anticoagulant (citrate and hirudin).
