Zusammenfassung
Die duale plättchenhemmende Therapie mit niedrig dosierter Azetylsalizylsäure (ASS) in Kombination mit einem P2Y12-ADP-Rezeptor-Antagonisten ist die in den aktuellen Leilinien der Europäischen Gesellschaft für Kardiologie empfohlene Standardtherapie für Patienten mit akutem Koronarsyndrom (ACS) und Patienten, bei denen eine perkutane Koronarintervention durchgeführt wird. Neuere P2Y12-Rezeptor-Antagonisten wie Prasugrel oder Ticagrelor bewirken eine stärkere und konsistentere Inhibition des P2Y12-Rezeptors und haben in klinischen Studien gegenüber der Kombination von ASS und Clopidogrel ischämische Ereignisse bei Patienten mit ACS reduziert. Dieser therapeutische Nutzen geht mit einer Zunahme des Blutungsrisikos der Patienten einher. Alternative Therapieansätze über additive Wirkmechanismen konnten im Wesentlichen die Inzidenz ischämischer Ereignisse ebenfalls senken, ohne das Problem vermehrter Blutungen zu lösen.
Abstract
Dual antiplatelet therapy with low-dose acetylsalicylic acid (ASA) and an inhibitor of the P2Y12 adenosine diphosphate (ADP) receptor is the standard treatment for patients presenting with acute coronary syndrome (ACS) or undergoing elective coronary interventions according to the current guidelines published by the European Society of Cardiology (ESC). New generation P2Y12 inhibitors, such as prasugrel and ticagrelor exert stronger and more consistent inhibition of the P2Y12 receptor. In clinical studies enrolling patients with ACS these drugs decreased the incidence of ischemic events compared to the standard therapy with clopidogrel and ASA; however, this beneficial effect was associated with an increase in bleeding events. Alternative therapeutic approaches via addition of drugs with different modes of action showed an overall reduction of ischemic events but also failed to uncouple this beneficial effect from an increased bleeding risk.
