Therapeutische Inhibition von Thrombozyten im akuten Koronarsyndrom und bei Koronarintervention: Mechanismen und klinische Ergebnisse Academic Article uri icon


  • Platelets play a crucial role in the pathogenesis of atherosclerosis and especially in the final ischemic consequences such as acute coronary syndromes. Furthermore, platelets are central mediators of acute or subacute complications of coronary interventions. Therefore, therapeutic inhibition of platelet function is of major interest in cardiology. The following review describes three different therapeutic strategies for platelet inhibition and provides a representative overview on the clinical results of studies based on these strategies.First, the mechanism of acetylsalicylicacid is described and the strong metaanalytic data demonstrating a convincing positive clinical effect is discussed. Second, the mode of action of the thienopyridines is described and initial clinical results are discussed. Third, the inhibition of the platelet integrin receptor GP IIb/IIIa is described as a potent way to block the final common pathway of platelet stimulation. The structural description of GP IIb/IIIa is followed by a structural classification of the available GP IIb/IIIa inhibitors. Clinical studies, meanwhile including several thousands of patients, are discussed based on representative examples. Finally, unresolved issues regarding the various GP IIb/IIIa inhibitors, such as differences in receptor affinity and specificity, intrinsic activation and GP IIb/IIIa inhibitor induced thrombocytopenia are, discussed.
