Abstract WP227: Association Of Anemia With Stroke Recurrence In Acute Ischemic Stroke: An Analysis From The Clinical Research Center For Stroke-5th Division Registry In Korea

Background: We have evaluated whether anemia at admission is associated with ischemic stroke recurrence and composite outcome events (stroke, myocardial infarction, and vascular death) according to the age, presence of cerebral artery stenosis, stroke subtype, and initial severity of stroke. Methods: All 27145 patients with transient ischemia attack or acute ischemic stroke admitted between April 2008 and November 2014 from the stroke registry of the fifth section of the Clinical Research Center for Stroke (CRCS-5) were selected. The association between anemia and 1-year stroke recurrence, composite outcome events according to age, presence of cerebral artery stenosis, stroke mechanism, and initial severity of stroke were evaluated. Results: The cumulative 1-year stroke recurrence rate, composite outcome events were significantly higher in patients with anemia than without anemia ( 7.2% vs. 4.8%, p Conclusion: Anemia is an independent predictor of 1-year ischemic stroke recurrence, composite outcome events of stroke, myocardial infarction, and vascular death. Our data suggests that more attention should be paid to the anemic patients with mild to moderate neurological deficit, small vessel occlusion subtype, and stroke of other determined etiology.
