Abstract W P14: Significant Correlation between Neurological and Functional Recoveries in the Natural History of Acute Ischemic Stroke from Large Vessel Occlusion

Purpose: There have been conflicting reports on the correlation between neurological and functional recoveries in acute ischemic stroke. NIHSS and mRS scores not always correlated in patients after treatment. Since the inconsistencies could be related to the variable effectiveness of treatments, the aim of this study was to test their correlation in patients with large vessel proximal occlusion who are eligible but not treated with endovascular therapy. In addition, we analyzed the data based on trichotomized ASPECTS scores to minimize the confounding influence of the infarct core. Methods: The FIRST Trial is a prospective natural history study of a stroke cohort eligible for but untreated by endovascular therapy and ineligible or refractory to IV rtPA. NIHSS and mRS scores were measured in 93 patients at admission, 24 hour and 7 days after hospital presentation and were analyzed by logistic regression against different core infarct volume as indexed by ASPECTS scores of 8-10, 5-7, and 0-4.
