Management of stroke in patients on antithrombotic therapy: Practical issues in the era of direct oral anticoagulants

Abstract

Antithrombotic drugs (ADs) are the mainstay of secondary prevention of thrombotic vascular diseases. Management of patients under long-term treatment with ADs admitted for acute cerebrovascular disease, either ischemic stroke (IS) or intracerebral hemorrhage (ICH), has become a frequent situation that might influence decision-making processes from diagnosis to therapeutic strategies. The aim of this review is to summarize current data from the literature to help clinicians in their decisions for stroke care in patients taking ADs. While a large body of data have made it possible to codify the management of patients presenting IS or ICH under antiplatelet drugs and vitamin K antagonists, the increasing use of direct oral anticoagulants (DOAs) and future development of new antiplatelet drugs raise new problems. Development of rapid assessment tools measuring specific biological activity and reversion agents dedicated to each class of DOAs should make it possible to optimize individual therapeutic strategies. This review highlights the main steps of IS and ICH management from early identification of ADs, and use of dedicated biological assays, to the stepwise strategy to apply revascularization or reversal therapies and finally the resumption of ADs with a focus on individual clinical and radiological characteristics for more personalized care.
