Efficacy versus safety: The dilemma of using novel platelet inhibitors for the treatment of patients with ischemic stroke and coronary artery disease

Abstract

Coronary and cerebrovascular atherothrombosis are the leading cause of mortality and morbidity worldwide. Novel antiplatelet agents have been established for the management of patients with clinically evident coronary atherothrombosis and are increasingly used in these patients. These agents, however, have shown limited Efficacy in the prevention of cerebrovascular events and potential harm in patients with history of stroke or transient ischemic attack. Herein, the Efficacy and safety of two established antiplatelet agents in patients with stroke - aspirin and clopidogrel - are reviewed with a focus on the use and challenges related to novel antiplatelet agents - prasugrel, ticagrelor, and vorapaxar - in patients at risk for and with a history of stroke or transient ischemic attack. © 2014 Iannopollo et al.
