Abstract TMP17: Revacept, an Inhibitor of Platelet Adhesion in Patients With Symptomatic Carotid Artery Stenosis. Safety Data From the International …

Introduction: Revacept is a novel vascular lesion-directed inhibitor of platelet adhesion and thrombus formation, exhibiting no effects on the homeostatic functions of circulating platelets. Objective: The effects of Revacept on plaque-mediated thrombosis were investigated in patients with symptomatic stenosis of the internal carotid artery (at least 50%, following ECST-criteria). Methods: Within an international, prospective, multicenter (n=16), randomized trial 158 patients could be randomized to receive placebo, or 40/120 mg Revacept by intravenous infusion over 20 minutes. Cerebrovascular events and cardiovascular complications were followed up to 3 months. Results: 158 patients were f…

Abstract Background The dual antiplatelet therapy (DAPT) duration is a matter of great interest among cardiologists. Because of the conflicting evidences and the necessity to balance the reduction in major cardiac events (MACE) occurrence and the risk of major bleedings after an acute coronary syndrome (ACS), there is a general consensus on prolonging DAPT on an individual basis. There is less consensus on which parameters are to be evaluated. Nowadays tests of platelet reactivity are not included in the decision-making. Few data are available on the prognostic value of aspirin response tests that are sensitive to other mediators of platelet adhesion and aggregation in vivo under flow condi…
Substantial Reduction of Platelet Adhesion by Heparin-Coated Stents
2001
Although optimized antiplatelet medication has improved the clinical outcome after coronary stenting, vessel occlusion and restenosis still remain a relevant clinical problem. Platelets play a key role in this process. Therefore, the authors compared the platelet adhesion on different stent surface modifications (electropolished without coating or coated with carbon, carbon and additional heparin, silicon carbide, or heparin alone) to investigate their role in reducing platelet adhesion. All stents and additional stainless steel plates were incubated in heparinized whole blood with radiolabeled platelets. After washing the stents and plates four times, radioactivity caused by the adhesion o…
