Abstract

There is a wide consensus that intensified antiplatelet therapy contributes to the reduction of major atherothrombotic complications in cardiovascular (CV) disease. In the setting of PCI (percutaneous coronary intervention) and acute coronary syndromes, dual antiplatelet therapy at optimal dosing and timing has significantly lowered the risk of thrombotic complications. There is a growing body of evidence that there is variability in response to antiplatelet treatments and this represents a potentially important clinical problem. Understanding the mechanisms underlying this phenomenon is important in improving patient care, but due to the diversity of factors involved, a clear predictive model for responsiveness to antiplatelet therapy is still missing. Attempts have been made to characterize the efficacy of antiplatelet therapy using platelet function testing but based on current information, its routine use is not recommended particularly as costs and cost effectiveness have not been established and agreement between laboratory methods is lacking. Hence, it is necessary to identify risk factors for decreased efficacy of standard antiplatelet drug treatment. It may be useful to adjust antiplatelet therapy based on individual risk assessment, especially as new platelet inhibitors are being introduced or are in development including prasugrel as well as the non-thienopyridines, ticagrelor, elinogrel, the ATP analog cangrelor, and thrombin receptor antagonists. This article focuses on antiplatelet therapy in patients at high risk for cardiovascular events and discusses the options for individual risk assessment and strategies to personalize therapy in the light of the large number of recent developments.
