The acute coronary syndrome (ACS) is one of the most frequent diagnoses in cardiology. The therapeutic corner-stones of ACS are PCI (percutaneous coronary intervention) and inhibition of blood coagulation. Current antiplatelet therapy consists of aspirin in combination with clopidogrel and glycoprotein IIb/IIIa blockade if needed. Prasugel is a new antiplatelet agent that is in the process of being approved for routine clinical use. In terms of antithrombotic therapy latest developments focus on drugs with anti-factor Xa activity, such as fondaparinux, or direct anti-thrombin activity, such as bivalirudin. This review discusses latest developments in the field of anti-platelet and anti-thrombotic therapy for ACS.
