Abstract

Objectives: Higher glycemia on admission has been associated with diffusion weighted imaging (DWI) lesions in patients with spontaneous intracerebral hemorrhage (sICH). However, the influence of longitudinal glycemia after admission and during a patient's hospitalization on DWI lesions in sICH has not been studied. Our aim was to compare longitudinal glycemia in sICH patients with and without DWI lesions. Material and Methods: Glycemia measurements were abstracted on participants enrolled in a prospective observational study examining predictors for DWI lesions in sICH. Univariate analysis was used to compare mean longitudinal glycemia in sICH patients with and without DWI lesions. Logistical regression was used to determine whether mean longitudinal glycemia was predictive of DWI lesions. Results: DWI lesions were found in 60 of the 121 (49.6%) participants. Mean time-to-MRI was 99.6 h (SD ± 89). During this time interval, 2,101 glucose measurements were analyzed with a median number of 7 (IQR 12, 1-261) measurements per patient. Mean longitudinal glycemia was higher in the DWI positive group compared to the DWI negative group until time-to-MRI (132 mg/dL vs 122 mg/dL, p = 0.03). Mean longitudinal glycemia was found to be predictive of DWI lesions (OR 1.02, 95% CI 1.005 to 1.035, p = 0.011). Conclusions: Mean longitudinal glycemia was higher in sICH patients with DWI lesions compared to those without DWI lesions. Future research into the association between higher glycemia and DWI lesions in sICH may provide insight into a pathophysiologic mechanism.
