Abstract TMP58: Neuroimaging Markers of Patient-Reported Outcomes in Acute Ischemic Stroke

Abstract

Objectives: To determine the relationship between patient-reported outcome measures (PROMs) and volumetric biomarkers assessed on clinical imaging in acute ischemic stroke (AIS). Background: AIS is a leading cause of long-term disability. White matter hyperintensity (V_WMH), brain (V_Brain) and stroke lesion volume (V_Lesion) have been linked as potential determinants of functional outcomes after stroke. Recently, there has been surging attention to PROMs, which allow for direct, patient-centered health assessments of stroke victims. However, the link between neuroimaging biomarkers and PROMs is not well studied. Methods: Patients presenting to the Emergency Department at Massachusetts General Hospital between February 2017 and February 2020 with a confirmed AIS on MRI were eligible and underwent a follow-up telephone interview, including PROM-10 questionnaires. V_WMH and V_Brain were automatically determined from clinical MRI. V_Lesion was manually segmented. Regression analyses were performed to identify associations of brain volumetrics and clinical variables with PROM-10 subscores and global mental and physical summary scores. Results: Utilizing data from 150 patients (mean age: 64.7; 41.9% female), higher V_WMH was associated with worse global mental (β = -0.65), global physical (β = -0.60), social activities (OR = 0.59), physical health (OR = 0.68), fatigue (OR = 0.69) and social satisfaction (OR = 0.66) scores. V_Lesions were associated with poorer global mental (β = -0.79), social (OR = 0.55) and physical (OR = 0.66) activities, mental health (OR = 0.68) and emotional distress (OR = 0.68) scores. Higher V_Brain was linked to better global mental (β = 0.93), global physical (β = 0.79), physical activities (OR = 1.72) and mental health (OR = 1.54) scores. Conclusions: Imaging biomarkers were significantly associated with PROMs. The inclusion of these markers with PROMs in routine post-stroke assessment can enhance our understanding of recovery.
