Research Abstract

To investigate whether HMG Co A reductase inhibitor inhibits in-vivo thrombus formation, we studied the effects of cerivastatin on rat carotid artery thrombus model, rat platelet activation and rat coagulation-fibrinolysis system. Cerivastatin significantly inhibited in-vivo thrombus formation. Crivastatin also significantly decreased platelet aggregation and platelet surface expression of P-selectin induced ADP, suggesting that cerivastatin inhibits platelet activation. Cerivastatin didn't affect rat plasma levels of fibrinogen, tissue factor, tissue palsminogen activating factor and tissue plasminogen activator inhibitory factor, suggesting that cerivastatin didn't affect rat coagulation-fibrinolysis system. Thus, HMG Co A reductase inhibitor may inhibit in-vivo thrombus formation by decreasing platelet activation.
