Improving patient selection for coagulopathy testing in the setting of acute ischemic stroke

To improve patient selection for specialized coagulation testing in the set ting of ischemic stroke, the authors sought to identify factors associated with the presence of hypercoagulable states. Of 208 patients with ischemic stroke tested, undetermined stroke subtype was significantly associated wit h the presence of coagulopathy, but only 60% were treated with warfarin. Th e frequency of coagulopathy in selected patients with ischemic stroke (5%) is low, and establishing the diagnosis did not uniformly influence treatmen t.
